C2000TM

150 MIPS

TI offers three distinct MCU product families optimized for different application segments.The C2000 family addresses the high end of the 32-bit MCU and low-end of the DSP market – often called digital signal controller (DSC) – combining DSP and microcontroller features on a single chip. The primary applications areas targeted are motor control and digital power supply. Up to 150 32-bit high-quality DSP MIPS are offered.The TMS470 is based on an industry standard ARM7TDMI architecture and was developed originally for 32/16-bit automotive applications. A focused subset of the product line is offered as general purpose devices for a wide range of industrial applications that include medical instrumentation, point of sale terminals and communication gateways.The MSP430 family targets ultra-low power metering and measurement applications in the 8 and 16-bit market space. The product line offers a wide range of catalog devices as well as application specific standard products (ASSP) solutions in the metering and portable instrumentation. The product family is noted specifically for lower power with devices starting as low as $0.49.

MSP430 - Mixed Signal Processor. The features of the MSP430 make it ideal for battery-powered measurement applications. Ultra-low Power; The MSP430 architecture is designed specifically for ultra-low power applications. Specific operating modes are implemented to reduce power consumption and extend battery life. The real-time clock mode uses as little as 0.8µA and can transition to industry leading 250mA / MIPS full-speed active mode in less than 1µs.Other important low-power feature such as zero-power brown-out reset (BOR) and extremely low pin leakage have enabled MSP430 customers to develop battery-based products that will last for over 10-years from the original battery! Over 100+ MSP430 devices are available integrating from 1KB to 128KB of Flash with 14 to 100 pins that allow a perfect fit for many applications. The MSP430 modern 16-bit RISC architecture reduces code size and allows advanced signal processing features not possible using conventional 8-bit MCUs. Intelligent mixed-signal peripherals including 10-16-bit ADC’s, comparators, DAC’s, LCD drivers and supply voltage supervisors support precision measurement. This allows applications to get implemented faster, using less code and power at lower cost.Applications operating at lower power, with smaller packaging and higher-precision analog benefit greatly from the MSP430’s embedded emulation. No external emulator is required as the device emulates itself. JTAG is used to communicate unobtrusively with the MSP430 in application. This means that all development is done under the same condition that will be seen in the final product. Using embedded emulation projects are developed faster, with few errors and at a lower cost.


• Extended Ultra-low Power standby• Interrupt-driven burst processing

Ultra-low Power Activity Profile

<1<1µµss

The MSP430 is designed specifically for ultra-low power applications. The total system power consumption is the absolute lowest, without compromise in performance. The system enters and remains in an ultra-low power standby mode as long as possible and is awoke only to service interrupts and then returns to standby mode quickly . This extended standby mode profile is common for many low-power applications that respond only to events once every few seconds, such as a thermostat or once every few hours such as a personal medical device. To service interrupt driven events, the software efficiently uses the 16-bit RISC CPU’s performance in very short, “burst” intervals. Transition from standby to full active is less than 1us. The MSP430 delivers a combination of ultra-low power and very high-performance on-demand.


Ultra-low Power Clock System

• Always-on low-frequency ACLK• On-demand high-speed DCO• DCO on and stable in <1µs

Multiple oscillators are utilized to provide both an ultra-low power standby mode and “on-demand” high-performance processing. The clock system is flexible and allows the MSP430 to operate optimally from a single 32kHz crystal sourcing an always on low frequency Auxiliary Clock (ACLK) with no additional external components. The ACLK enables the MSP430’s ultra-low-power standby mode (LPM3) and an embedded real-time clock function. Optionally, the new embedded 12kHz internal very-low power oscillator (VLO) on the MSP430F2xx on F5xx families can be used to source the ACLK. In LPM3, the MSP430 typically consumes less than 1µA. The integrated high-speed DCO sources the master clock (MCLK) used by the CPU and high-speed peripherals. By design, the DCO is active and fully stable in less than 1µs with no intermediate steps. This enables “instant on” high-performance processing – no long start-up for a second crystal or 2-speed start-up required. Because the DCO is software configurable the clock can be tuned to the application requirementsThe MSP430 can also operate using only the internal DCO and VLO using no external components. High-speed crystals can also be used for high performance applications.

VIDEO CLIP:The embedded clip demonstrates LPM3 standby mode of the MSP430. In each case, the CPU wakes up on a timed interrupt interval base on the ACLK source and the watchdog timer and blinks the LED in software. The 1st portion is LPM3 via the external 32.768kHz crystal providing a current consumption in the 0.5uA range. The 2nd portion is again LPM3, but instead of an external watch crystal, the internal VLO is used. LPM3 current consumption is much lower at ~0.3uA.

Performance on-Demand

Interrupt

DCO2-SpeedStartup

The screen capture shows the actual startup of an MSP430 digitally controlled oscillator (DCO).In this example it can be seen that from an interrupt event, the DCO is active and stable in well under 1µs – in this example the measured F2131 DCO startup time is actually 204ns. With the MSP430 clock start up is “instant-on”. With the DCO, no delay or 2-speed clock startup occurs. The users application has instant access to the high-speed DCO from any operating mode. A common benefit of an instant-on and stable high-speed oscillator is response to serial communication, a UART for example. The clock source for the UART must start and be stable instantly to prevent received characters from being lost. If a slow or 2-speed oscillator is used, the first character in the received data stream is lost.Instant-on saves power as the system does not have to waste energy waiting for oscillator startup. Events are serviced immediately.


Why Ultra-low Power Is Important• Longer battery life• Smaller products • Simpler power supplies• Less EMI simplifies PCB• Permanent battery• Reduced liability

So why is ultra-low power so important?The most apparent benefit for low-power is realized in battery powered applications allowing the use of smaller, lower cost batteries.Power supplies are simpler and lower cost, and in many applications direct battery supply can be used.Generated EMI is very low because the MSP430 is so low power and can operate effectively at low-frequencies.A benefit in battery powered applications is the idea of permanently installed batteries. By installing sealed batteries at the factory in an application such as meters, sports equipment of portable medical devices, the liability of replacement is eliminated. With the ability to operate <1µA, products can operate from a single lithium battery for over 10-years.

10-year Embedded Real-Time Clock

The MSP430’s <1uA ultra-low power stand-by mode – or LPM3 – capability allows and embedded real-time clock function to be added to any application.In this example an MSP430F20x1 system normally in LPM3 at ~0.8uA. Operating in LPM3 the watch-crystal oscillator (ACLK), a timer, and all interrupts are active. Once every second, the timer clocked by ACLK overflows and interrupts the CPU which automatically starts the DCO. The CPU updates software based clock registers operating from the fast DCO – not the slower ACLK. The update of the clock registers takes less than 100us.Because the active duty cycle for the embedded real-time clock function is so low - 100/1000000 - the incremental current consumption is only 30nA for the function.

The MSP430 uses a single unified memory address map for code, data and peripherals. There is absolutely no paging with direct access to program and data anywhere throughout the entire address space, which includes Flash, ROM RAM and peripherals with no restrictions. Support for agile unrestricted code including branching, subroutine calls, function calls, and interrupts. All of the Flash and RAM memory can be addressed as either 8-bit bytes or 16-bit words. Peripheral module addresses are collected below 0x200. The complete instruction set and all addressing modes can be used to with peripherals. Flash is segmented into 512Byte main memory segments. Additional smaller information memory segments are also available. The only difference between main and information memory is size – code and data can be located anywhere. The total number of main memory segments depends on the device -for example, a 4KB device has eight main memory segments. Flash memory operates from 1.8V – 3.6V. Programming/erase voltage is 2.7V (reduced to 2.2V on the‘F2xx). Flash can be erased and reprogrammed 100k times with 100-year data retention. 60kB of Flash can be programmed in as fast as 2 seconds. There are three methods of programming Flash; Out or in-system using JTAG, a Bootstrap Loader (BSL), or in-system using normal software. The bootstrap loader is a section of ROM code that resides on the device itself and allows communication using a common 9600-baud UART protocol. The sequence to self-program Flash memory is very easy with timing controlled by hardware, thus making it well-suited for data storage during application runtime. In most cases this can help eliminating the need for an external EEPROM. For security reasons, Flash cannot be programmed or erased unless a password is used when the Flash control registers are accessed. During programming and erase, program execution out of Flash memory is automatically halted. After the operation software, resumes with the next instruction and any enabled interrupts that occurred during the programming or erase operation are automatically serviced.


Modern 16-bit Orthogonal RISC CPU• No accumulator bottleneck• RISC architecture

27 core instructions24 emulated instructions7 addressing modesConstant generator

• Single-cycle register operations

• Memory-to-memory atomic addressing

• Bit, byte and word processing

Modern 16-bit RISC CPU is optimized for modern programming techniques.The MSP430’s architecture provides the flexibility of 16 fully addressable, single-cycle 16-bit CPU registers. The large CPU register file eliminates what is typically a single working file or accumulator bottleneck. The CPU registers are fully accessible including the program counter, stack pointer, status register and 12 working registers. The modern Reduced Instruction Set (RISC) design of the CPU offers versatility through simplicity using only 27 easy-to-understand instructions and 7 consistent addressing modes. All memory spaces – Flash, RAM, peripherals and CPU registers - use the exact same instructions and addressing modes. All instructions can also be used in a 16-bit word (.w) or 8-bit byte (.b) format. The MSP430 is an orthogonal design because all instructions and addressing mode are used consistently though all areas of the device. The CPU also integrates a constant generator to automatically generate the six most used immediate values. The constant generator has the effect of reducing code size by generator this common constants (or literals) using hardware, eliminating what would be immediate values embedded in code.To support real-time programming and save code space, the CPU also supports atomic – uninterruptible –memory-to-memory operations with the full instruction set. No intermediate register operation is required. Up to 16 MIPS of performance is available today on the newest 2xx family, with more planned.The result is a 16-bit, ultra-low power CPU that has more effective processing throughput, is smaller in size, and more code-efficient than other 8/16-bit microcontrollers. When using the MSP430, this results in programmers writing less lines of code. Now it’s possible to develop ultra-low power, high-performance applications at a fraction of the code size previously possible.

The example shows how powerful a modern instruction set is in a real-world application. A code efficient architecture like the MSP430 not only reduces code size and execution time but also reduces the lines of code required for a given function. Using indirect addressing with the MSP430, in a single line of code, a display character can be written directly to a port to illuminate a seven segment LED display for example. In the example, the variable DispVal holds the value to be displayed. A look-up table decodes the character map directly which is written directly to the port in a single instruction. Because the MSP430 is a Von Neuman architecture, the data table can be located anywhere in the memory map. Comparing the MSP430 to another common 8-bit MCU, the power of a modern instruction set is seen. The MSP430 requires only 128 bits of total program and lookup table memory for the function in the example. The other MCU requires 238 bits for the same function.

Do You Use A 10-bit ADC?

The example shows the effectiveness of the MSP430’s 16-bit architecture in a common function -servicing an integrated 10-bit ADC and saving the conversion code to RAM.The MSP430 can move any 8 or 16-bit value from any memory location to any memory location in theentire address space in one fully atomic (uninterruptible) instruction. The 8-bit MCU requires numerous instructions, and is forced to break the 10-bit ADC output into two bytes. The limitation of an accumulator based architecture is also shown with data always passing through the accumulator. The need to always pass data through the accumulator and being forced to change memory pages with the 8-bit MCU increases code size, reduces performance and increases power consumption.


Compiler Friendly

• Instruction set and register orthogonality• Direct stack addressing for passing parameters• Application report SLAA205

Many applications today are developed in high-level C code. To achieve the highest C code efficiency, first consider what a compiler wants. Compilers prefer instruction set orthogonality and many registers that operate identically to be free to allocate resources without restrictions. Compilers also use the stack for passing parameters and for storing temporary variables.With these facts and guidelines, the MSP430 architecture was developed as follows:Orthogonal instruction set – although the MSP430 architecture implements only 27 instructions, every instruction is usable with every addressing mode throughout the entire memory map. This enables a very compact instruction set to implement a very large feature set with a strongly simplified, lower cost and lower power CPU.High register count – In addition to the program counter and stack pointer, twelve identical general-purpose 16-bit CPU registers are available. Page free – The 16-bit architecture of the MSP430 allows the direct addressing of the entire 64kB memory address space. Stack processing – The stack pointer has the full addressing capabilities of a general purpose register which allows any needed manipulation of data on the RAM-based stack. Usability of jumps – eight single word conditional jumps with a large +512 reach are implemented. Three addressing modes (symbolic, absolute and immediate) allow fully atomic memory-to-memory operations with the complete instruction set. These addressing modes drive significant code savings and superior performance. Byte and word processing – Any instruction can be used with 16-bit word or 8-bit byte data type. This feature is especially useful for table processing allowing the use of the most code efficient data type.Constant generator – The constant generator automatically generates the six most used immediate constants in hardware.

MCU

The MSP430 introduced the industry’s first zero-power Brown-Out Reset (BOR) protection. The screen shot shows a typical battery insertion and real example of brownout.The BOR forces a MCU into reset both on power-up when VCC rises and when VCC falls below normal operating range, but not fully to ground. Because MSP430 BOR is zero-power and fully active in all operating modes, the most reliable operation is ensured under all conditions.Competitor’s BOR protection is in the 10-50µA range and proposed to be deactivated in low-power modes to save power – this is not practical as a BOR condition cannot be predicated and can easily occur even in a low-power mode. BOR must always be on for maximum reliably.All F2xx devices, all F4xx devices, the F16x, F15x, F1xx2 and all future MSP430 devices have zero-power BOR.

The MSP430’s dedicated embedded emulation logic resides on the actual device itself and is accessed via industry standard JTAG using no additional system resources. From the first day of development, firmware engineers can now unobtrusively develop and debug their embedded code with full-speed execution, breakpoints, and single steps in an application. Embedded emulation becomes even more important with high performance mixed-signal systems that must maintain the integrity of microvolt analog signals. Signal integrity is virtually impossible with cumbersome in-circuit emulators that are sensitive to cabling crosstalk. And unlike abstract background debuggers, no time-sharing of system serial communication resources is required with embedded emulation on the MSP430.By combining the flexibility of in-system programmable Flash memory, unobtrusive embedded emulation, and a common user interface, development time is reduced. And, should the situation arise, last minute code updates as well as remote scheduled and unscheduled upgrades can also be made.Access to the JTAG port can be permanently disabled using a non-erasable fuse.

The MSP430 is designed specifically for battery-power measurement applications.The clock system allows many low-power modes with no compromise in performance. Because of a wide operating voltage range, the MSP430 can often be powered directly from a battery.The MSP430 BOR implementation is truly ultra-low power, in the nA range and practical for all applications. The MSP430 BOR function is so low power that this functions is always active, even in all low-power modes. This ensures the most reliable performance possible. Competitor’s BOR protection is in the µA range and not usable in ultra-low power battery powered applications, which leave the application vulnerable to BOR conditions.The port pins have very low leakage when connected to external signals. This is very important as many MCU’s have several µA of input leakage on each port pin. The overall MSP430 architecture including a 16-bit CPU with 16 registers and 16-bit data and address buses minimize power-consuming fetches to memory. A fast vectored-interrupt structure reduces the need for wasteful CPU software flag polling.Many intelligent peripheral features are provided that allows tasks to be completed independent of the CPU and far more efficiently. These include the autoscan feature in the ADC12 and the available DMA. With the intelligent peripherals, the CPU does not need to be over clocked to deliver the required system performance. Always review manufactures worst case or maximum values. Many specifications are dramatically effected over temperature.

100+ Code Compatible Devices

The MSP430 is world’s most popular low-power MCU architecture with 100 compatible devices in production today.The MSP430x1xx family was introduced in 2000 to address requirements for catalog low-power MCU applications. The F1xx family spans from the entry-level C1101 ROM device starting at $0.49, to highly integrated F16xx devices with up to 60kB of Flash / 10K RAM, 12-bit ADC, 12-bit DAC and a DMA controller. The F1xx family introduced the world’s ultra-low power Flash and is specified for operation at up to 8-MIPS from 1.8V to 3.6V. All F1xx family members are in high-volume production. Existing F1xx devices are encouraged for new designs, though no new F1xx devices are planned. Future catalog MSP430’s will be developed in the F2xx family.The MSP430F4xx offers application specific standard products (ASSP) solutions targeted to metering and measurement equipments. The F4xx complements the F1xx family adding an LCD driver, zero power BOR on all devices and an enhanced Frequency Locked Loop (FLL) clock system. The F4xx family has the same operating characteristics as the F1xx including ultra-low power Flash operation at up to 8-MIPS from 1.8V to 3.6V. The F4xx offers a high-resolution 16-bit sigma-delta A-D converter, operational amplifiers, and other mixed-signal intelligent peripherals ideal for single-chip metering and measurement applications. Additional F4xx derivatives are planned and the family is encouraged for new designs.The MSP430F2xx family provides twice the processing performance at half the stand-by power consumption compared to MSP430F1xx devices. The F2xx family offers enhancements that reduce overall system cost and improve reliability making these new devices an ideal roadmap solution for existing low power F1xx designs or as a launch point for new applications. The F2xx family began introduction in 2005 and will continue for the next several years.The MSP430x5xx is planned to be previewed late 2006 with introduction in 2007. The F5xx family will be fully compatible with existing MSP430’s offering expanded memory, more speed and a variety of new peripherals. Additional F5xx information will be available fall 2006!

F1xx Multi-Purpose Devices

The MSP430x1xx family was introduced in 2000 to address requirements across a wide range of low-power applications. The F1xx family introduced the MSP430’s ultra-low power Flash and is specified for operation at up to 8-MIPS. The specified operating range is 1.8V to 3.6V. The F1xx family spans a wide variety of devices from the entry level MSP430C1101 ROM device starting at $0.49, to highly integrated F16xx devices with up to 60kB of Flash, 12-bit ADC, 12-bit DAC, DMA controller, and up to 10K RAM. MSP430x1xx family members are the most popular MSP430 family, in high-volume production with no plans for obsolescence. No new MSP430x1xx family members are planned, though existing devices are encouraged for new designs if they meet the application requirements.


• Most complete and flexible MSP430F1xx device• Popular MSP430 64-pin footprint

F16x System-on-Chip

The MSP430F16x/15x are 100% pin compatible and are functional extensions of the popular ‘F14x/13x series. The 64-pin footprint these device share is the most popular throughout the entire MSP430 portfolio. A complete peripheral mix provides maximum flexibility.The F16x introduces a Direct Memory Access controller (DMA) controller that allows programmable and automatic data handling from any memory location to any memory location. The DMA frees the CPU from basic data handling improving performance in many applications by up to 10X. When combined with the integrated 12-bit ADC and two independent 12-bit DACs, a complete, very-high performance, signal chain on-chip can be implemented.The zero-power brown out reset (BOR) provides protection against supply voltage disruptions. A programmable supply voltage supervisor is also added for very accurate supply voltage monitoring. If the supply falls below a programmed level, the device can be configured to completely reset, preventing errant operation.The USART0 is enhanced to support full master/slave I2C operation in addition to the UART and SPI modes.

DMA

The benefits of using DMA for repetitive data handling are very significant in real world applications The example shows an instrument that must generate a 32-step 10kHz sine wave into a sensor. This means that 320k DAC transfers are required. Without DMA, the typical interrupt driven software solution quickly becomes overloaded just managing the serial transfers to the DAC. The DAC Load ISR requires 53 CPU cycles to fetch the required data from a look-up table, increment an pointed, increment a pointer, check pointed for out of range and load the fetched data – which is equivalent to > 16MIPS.With DMA the total system clock requirements are 0.64MIPS – DMA reduces system overhead in this example by over 25X.With DMA and signal-chain-on-chip the performance of a system is dramatically increased and the MCU resources are available for more advanced signal processing. This means that MSP430 applications can operate at lower clock speeds - reducing power consumption and EMI – and deliver higher performance.

New MSP430FG461x

The MSP430FG461x is planned for production release mid-2006 targeting high-end portable medical applications. The integration of the FG461x allows high-performance complete system on-chip solutions. The FG461x is the first ‘430 family to incorporate the new MSP430X extended architecture that supports direct linear access to up to 1MB of memory, 16 times more memory compared to the 64kB available today with the MSP430. The MSP430X is 100% compatible with the existing MSP430 allowing existing code libraries to be reused. Extended addressing modes are incorporated that allow the existing MSP430 instruction set to operate page-free throughout the entire 1MB memory model with improved code density faster using fewer clock cycles. Extended instructions designed for the large memory allow optimal high-level code density with full backward compatibility, making it possible to develop very sophisticated real-time applications completely in modular C libraries.The FG461x utilizes the F4xx FLL Clock System, Basic Timer, Timer_A and Timer_B. An enhanced LCD_A driver is included that incorporates a boost converter and contrast control independent of VCC. The improved watchdog timer (WDT+) offers protection against run away software, invalid address CPU fetches as well as a protected clock source. These features reduce overall system cost and improve reliability. A new real-time clock module supports seconds, minutes, hours, days and months. An ADC12-DMA-DAC12 and 3X OPAMPS support a complete high-performance signal chain on-chip. The FG461x integrates up to 120kB of embedded Flash and 8kB of RAM.A dual-channel Universal Serial Communication Interface (USCI) is also included. The USCI supports asynchronous and synchronous communications modes. The USCI has two independent blocks, USCI_A and USCI_B. USCI_A supports UART/IrDA or SPI.USCI_B supports I2C or SPI. USCI_A and USCI_B can be used at the same time.

Extended addressing modes are incorporated that allow the existing MSP430 instruction set to operate page-free throughout the entire 1MB memory model with improved code density faster using fewer clock cycles. Extended instructions designed for the large memory allow optimal high-level code density with full backward compatibility, making it possible to develop very sophisticated real-time applications completely in modular C libraries.The MSP430X executes MSP430 code unaltered in the compatible 64kB memory range. To further preserve compatibly, all MSP430X interrupt vectors, RAM and peripherals registers map exactly to the MSP430. The extended memory contains expanded code and data.Existing MSP430 byte/word (.b/.w) addressing modes are expanded allowing direct access to 20-bit addresses (.a) fields which support 1MB (20-bit) program flow and pointer capability. This 20-bit address-word capability is accomplished for program flow, stack manipulation and pointer handling with same code density as the 16-bit MSP430 by using un-used bits in OP codes field. Additionally an extension word allows full 20-bit addressing for source and destination with any MSP430 instruction and addressing mode and added repetition capability.Cycle counts have been reduced for several addressing modes and interrupt overhead allowing faster code execution.Additional details regarding the MSP430X architecture can be found in the MSP430F4xx and MSP430F2xx users guides.

The MSP430F2xx family provides twice the processing performance at half the stand-by power consumption compared to earlier MSP430F1xx devices. In addition, the MSP430F2xx family incorporates enhancements that reduce overall system cost and improve reliability making these new devices an ideal upgrade solution for existing MSP430 designs or as a launch point for a variety of new applications. Many new F2xx family devices are planned for introducing throughout 2006 and 2007; The F2xx family will include members that are pin and functionally compatible with F1xx devices offering even lower power, more speed, BOR, WDT+ on every device along with a variety of new peripherals. Unique F2xx derivatives with new peripherals are also planned. New peripherals such as a USCI (USART/SPI/I2C/IrDA), larger memory sizes (120kB Flash) and low pin count device variants will be introduced.

The MSP430F2xx family provides twice the processing performance (16MHz versus 8MHz) in terms of maximum CPU clock speed at half the stand-by power consumption compared to MSP430F1xx devices. In addition, the F2xx family incorporates a variety of enhancements including zero power brown-out reset protection on all devices, lower power and lower voltage flash programming, an improved failsafe low frequency (LF) and high-frequency (XT) crystal oscillator system. An improved watchdog timer (WDT+) offers protection against run away software, invalid address fetches as well as a protected clock source. The features reduce overall system cost and improve reliability. The digitally controlled oscillator (DCO) is improved with greater stability over temperature and voltage allowing, in most applications, the elimination on an external crystal. All port pins now have programmable pull-up/pull-down resistors eliminating external components. The bootstrap loader is improved including an option that an invalid password will erase the device, which prevents hacking. The graph shows the expanded operating range of all MSP430F2xx devices as compared to MSP430F1xx devices. The F2xx maximum operating frequency has been doubled to 16Mhz from the 8Mhz maximum of the F1xx. The F2xx 16MHz maximum system frequency is also specified as low as 3.3V allowing margin from the maximum Vcc of 3.6V. On the F1xx, the maximum system clock is specified at exactly 3.6V with no margins. The minimum voltage allowed for Flash programming/erasing on all F2xx devices is reduced to 2.2V allowing batteries to be drained longer.F2xx derivatives are offered with extended 105°C temperature capability. Automotive temperature and qualification will not be offered.The F2xx family of devices offers many improvements, but shares the same CPU and instruction set as all MSP430’s – this means existing code can be completely reused.

To support the lowest power consumption and performance on-demand, the enhanced basic clock system (BCS+) on the MSP430F2xx (like all other MSP430 clock systems) typically provides two clocks. A low frequency auxiliary clock (ACLK) is typically sourced directly from a common 32 kHz watch crystal and is used for always-on low power peripherals. A high-speed clock is generated on-chip from an instant-on digitally controlled oscillator (DCO) used by the CPU and other peripherals. To save power, an application’s interrupt events steer the usage of the DCO only when required. The majority of the application’s life is spent in standby mode with high-performance available on-demand and only when required.Reduced standby power consumption also known as real-time clock (RTC) or LPM3 mode current has been reduced to less than 1 micro amp. This power consumption can be achieved using an external 32kHz crystal or the VLO. The F20xx introduces a new very-low power oscillator (VLO) as an alternative to the typical 32kHz ACLK. The VLO provide a 12kHz on-chip oscillator with no external components that is perfect for ultra-low power applications that need a wake-up function, but the precision of a 32kHz crystal.The F2xx crystal oscillator is improved providing programmable integrated crystal load capacitors allows the use of a wider range of crystals and elimination of external components used typically to stabilize oscillation. Failsafe crystal oscillator can trigger a non-maskable interrupt and start the on-chip oscillator for failsafe operation. This feature is always available with no additional power consumption in both high-frequency and low frequency modes. Crystal min-pulse input de-glitch filters reduce the possibility of externally introduced high frequency system noise and improves reliability.Improved on-chip digitally controlled oscillator (DCO) offers a sub 1 micro second start with +2.5% accuracies and 16MHz operation over temperature and voltage.

VIDEO CLIPThe embedded video demonstrates the enhanced features of the WDT+ to auto-detect ACLK failure and switch to the DCO, maintaining operation of the application.

MSP430F20xx

Modern consumer and portable applications do not leave much room for electronics such as the electric toothbrush shown. The MSP430F2xx incorporates many features that eliminate the need for space consuming external components.The MSP430F2xx port 1 and port 2 have user selectable internal pull up/down resistors. Using the internal pull up/down resistors can eliminate the need for external components saving space and reducing cost. This space savings is particularly important in portable applications. Consider the 4mm x 4mm footprint of the QFN package available with 14 and 20 pin F2xx devices is equivalent in size to just two 1206 style resistors. In many applications, the space consumed by external components can quickly surpass that of the MCU itself.An internal high-speed digitally controlled oscillator (DCO) programmable from 100kHz to 16Mhz eliminates the need for an external crystal in most applications. If an external XTAL is required, to save additional space and cost, user programmable XTAL capacitors are integrated. The MSP430F20xx introduces a very low-power oscillator (VLO) that allows a self-wake up standby mode of less than 1µA without an external components.

New F20xx Low Pin-count

The low pin-count MSP430F20xx are based on the F2xx architecture that operates with an active current of 200 µA / MIPS and a standby mode with self wake-up well under 1µA. A flexible clock system allows operation up to 16 MHz with no external components using an improved digitally controlled oscillator (DCO) that is fully programmable and stable over temperature and voltage. The ability to switch from standby to a fully synchronized 16 MIPS active mode in less than one micro-second allows interrupt event-driven programming that extends time in power-saving modes and the use of smaller, lower cost batteries. The F20xx extremely small footprint combined with sub 1µA standby current provides benefits is space constrained applications such as fire and motion detectors where now products can get developed with permanent sealed batteries and that can exceed 10 years of operation. The liability of battery replacement can be eliminated with the product considered disposable. The pin-compatible F20xx series operates from 1.8V – 3.6V and is 100% code compatible with all other MSP430s, allowing developers to leverage a single MCU platform from the most basic to the most sophisticated applications. The F20x1 includes an analog comparator, the F20x2 a 200ksps 10-bit A/D converter and the F20x3 a precision 16-bit sigma-delta A/D. All devices offer in-system programmable Flash for greater design flexibility, field upgrades and elimination of external EEPROMs. To further reduce system cost, all 10 GPIO pins include programmable pull-up/pull-down resistors eliminating external components. A zero-power brown-out reset (BOR) function and an enhanced watchdog timer enhance reliability. All the failsafe features of F2xx are available during all modes of operation with no power penalty. The MSP430F20x2 and MSP430F20x3 include a universal serial interface (USI) that can be configured for either I2C or SPI master or slave communication.

• Interrupt Driven• Reduces CPU load

The MSP430F20xx includes a USI module that provides the functionality to support synchronous serial communication. The USI is a very high-performance serial interface especially in a low pin-count device.The USI is an 8- or 16-bit shift register that can be used to output data streams, or when combined with minimal software, can implement serial communication. In addition, the USI includes built-in hardware functionality to ease the implementation of SPI and I2C communication. The USI module also includes interrupts to further reduce the necessary software overhead for serial communication and to maintain the ultra low-power capabilities of the MSP430.The USI module features include:- Slave operation in LPM4 - no internal clock required- Programmable clock generation- Selectable clock polarity and phase control- Three-wire SPI mode support, variable data length, and selectable MSB or LSB data order.- I2C mode support, START and STOP detection for I2C mode with automatic SCL control, arbitration lost detection in master mode.

The example shows the advantage of using the USI module compared to software in a synchronous serial communication application that exchanges 16-bits of data between an MSP430F20xx master and a peripheral device. The USI is a very high-performance serial interface in a low pin-count device.The USI hardware provides a significant advantage in terms of reducing CPU load. Because the USI clocks data into and out of the MSP430 in hardware, the CPU does not have to do this in software. Eliminating the burden of shifting data with software, frees the CPU for other tasks and reduces power consumption. The loop to shift data in and out in software show requires 26 cycles per bit which when multiplied by 16-bits, results in a total of 425 CPU cycles for an entire transfer when done in software. Using the USI only 10 CPU clocks are required to load the data – the synchronous shift is done in hardware.

The ADC10 is a fast, flexible 10-bit ADC. Up to sixteen inputs are available to measure external signals. The complete sample/conversion time is under 5µs supporting greater than 200ksps. The sample time is programmable to allow engineers to account for the impedance of external sensors.An independent temperature sensor and low-battery detect channel are also integrated. The 1.5V/2.5V internal voltage reference, VCC or an external reference can be used. The output from the ADC can be in binary or signed format. The ADC10 offers several features to reduce CPU loading, improve performance, and lower current consumption. A sample start can be triggered with software, or, by using an output from a timer for a precise start independent of CPU activity (SOC = Start Of Conversion). User software does not have to be burdened to start a conversion. It can be done more precisely, using less code, with timer hardware.Auto-scan allows channels to be sequenced automatically (for example A3-A2-A1-A0 A3-A2-A1-A0) without CPU intervention. Again, this relieves the software from performing this basic, but important task in many multi-channel applications.The Data Transfer Controller (DTC) is used to automatically transfer ADC10 conversion results directly to memory without CPU intervention. This feature allows fast conversion throughput (200ksps+) to run continuously without the software intervention. The DTC transfers the output of the ADC10 directly to any memory location, which can be configured as a buffer, up to 256 bytes. The DTC can transfer continuously into the buffer, automatically incrementing, and interrupt the CPU when the buffer is full, or ½ full. For each DTC memory transfer, one bus cycle is required, in which the CPU is automatically halted to avoid and bus contention. The CPU and software can focus on higher-level data processing and not on basic data movement. More advanced products can be designed using the ADC10 that use less power and less code space.

The Data Transfer Controller (DTC) relieves the CPU for the basic task of data handling.For example, a system sampling three channels, without DTC, the processor is burdened with 70 cycles for each sample. If, for example, 20KSPS were required – or 60KSPS total – a system without DTC would be burdened 4.2MIPS. The same processor with autoscan and DTC requires only 0.06MIPS system load. This means that in a system with autoscan and DTC, the CPU is free for other tasks and the system can operate in a lower frequency power-saving mode with DTC.Much higher sampling speed can be attained without increasing the clock speed.

Ordinary Motion Detector

• 20µA – 2mA • Complicated• Fixed function

An ordinary motion detector uses an external circuit consisting of a two-stage analog gain stage followed by a comparator to interface to a passive infrared sensor (PIR). In the presence of motion, the comparator will output high, which triggers an input on a microcontroller. The interface circuit is fixed function and consumes typically 20µA to 2mA of current. The solution is relatively high-power offering little flexibility


F20x3 Improved Motion Detector

• <10µA total system power~6µA PIR~3µA measurement~0.5µA LPM3 using VLO

• No crystal needed – VLO• Enhanced watchdog • Fully programmable SoC• Very low cost

An MSP430F20x3-based motion detector circuit based on a passive infrared (PIR) sensor is shown. Because of the F20x3 high-precision 16-bit sigma-delta ADC, the circuit is very straight forward and low-cost. The F20x3 solution is configured in LPM3, clocking only a timer with the VLO oscillator – no crystal is required. In this mode, the F20x3 consumes approximately 0.5µA. Approximately 3 times per second, the MSP430 is interrupted and samples the sensor output with the SD16_A. The each sample takes ~1ms and consumes approximately 900µA during the sampling. This means approximately 2.7µA on average is required for the measurement function. The PIR requires approximately 6µA, the MSP430F20x3 in LPM3 0.5µA, and the measurement function ~3µA resulting in an average total system power consumption of less than 10µA. The F20x3 USI module allows high-speed serial communication with another system with little CPU load saving code space and power consumption. The very low-power oscillator (VLO) can be used for an ultra-low power stand-by mode requiring no crystal.Because the F20x3 solution is fully programmable, many additional differentiated features can be added.The interface to the PIR sensor is direct to the embedded 16-bit sigma-delta ADC eliminating external components saving cost and power consumption.

The example demonstrates an ultra-low power, fire detector using the MSP430F2274An IR-LED based smoke chamber is used as a sensor to measure reflected light – if smoke is present, more light is reflected and seen on an IR-transistor as a current output. One of the F2274’s two available OPAMPs is used as a trans-impedance amplifier to convert the sensor current to a voltage. The F2274’s internal ADC10 measures the voltage output from the OPAMP to determine the amount of smoke present. Temperature is measured using a negative temperature coefficient (NTC) resistor and a reference resistor divider. The ADC10 measures the voltage of the divider to determine the NTC’s resistance and associated temperature. If the smoke is present and temperature is above a safe range, an alarm is issued.The application operates normally in stand-by mode LPM3, with all components shut down, except the MSP430F2274’s internal very low-power oscillator (or ultra-low 32kHz oscillator) and a timer. The timer will overflow at a programmed interval of 8-seconds and power will be applied to the OPA and LED in the smoke chamber. The application runs completely from the MSP430’s internal DCO with no external clock sources required. Factory pre-programmed DCO calibration constants are available to meet different speed requirements.




Describe the evolution of the MCU emulator, ez430 details, and basic ez430 demonstration.


Emulator Evolution

2006 – $20

2000 – $100’s

1994 – $1000’s

The MCU emulator has gone an incredible evolution during the past decade making the process of embedded design both easier and lower cost. The original method of emulation was an in circuit emulator (ICE) which reproduced the function of the target processor in a separate box. The ICE concept provided a temporary window into the embedded processors functionality while inserted into the end application. An ICE used an ASIC, FPGA, or special bond-out version of the target device to emulate the required functionality. A cable connects the ICE to the application matching the footprint of target device. Another cable connects the ICE to a PC allowing communication and control of emulated device while resident in the application. A power supply is required as well. The problem with the ICE is that it never exactly emulated the target device causing problems to surface when moving from emulation to production. As devices became smaller and projects more portable, it became impossible for the ICE cable to fit in the target application. And with high-performance analog peripherals, it is also impossible to maintain signal integrity via a long external cable. Placing dedicated logic on the target device and Flash memory brought the introduction of embedded emulation. With embedded emulation, the code is developed in-application and in-system saving time because the all development is subject to the exact same electrical characteristics as the final application. The same device and application system is used for development and production. Code runs full speed on the target device. Using dedicated signals to access the target device, development is non-obtrusive with not using any normal target device resources. All MSP430 use embedded emulation.The eZ430-F2013 takes embedded emulation a step further reducing cost and marking the system smaller and even more convenient. The development tool includes everything needed for a new user to evaluate the MSP430 family in minutes or, for a professional developer, the needed resources to complete and entire MSP430F20xx project – all encased in USB stick case and for only $20!

Detachable Target Benefits

• Not just a demo• Separate emulator to debug remotely• Build a complete stand alone project

Because the eZ430 target board can be disconnected from the emulation interface, the complete tool is much more than a demo or evaluation system. An entire MSP430F20xx project can be implemented using just the eZ430. Competing basic demo or evaluation systems contain the emulation and target device on a single board preventing a stand alone project implementation. The emulation interface can not be separated from the target device. Only simple demonstrations or limited evaluation are possible.

VIDEO CLIPThe embedded video clip shows the full functionality of the eZ430 as a development tool for customer applications. With the target board removed, the 2-wire JTAG header can be interfaced via custom cabling to a user’s ‘F20xx system. When connected, the eZ430 emulator can download and debug code with the complete functionality of other MSP430 FET tools. As an example, the ‘F2013 motion detector application is interfaced, programmed and debugged. Breakpoints as well as variable monitoring are demonstrated.
