Hitachi to Release the H8S/2134F and H8S/2144F 16-bit Microcontrollers with

On-Chip Single-Voltage Power Supply Flash Memory

- Microcontrollers designed for computer peripherals such as CD-ROM and DVD drives

and commercial equipment achieving 20-MHz high-speed and low power operation -

Hitachi, Ltd. announces the release of two products, the H8S/2134F (80-pinversion) and the H8S/2144F (100-pin version) of H8S Series, which are theHitachi's high-end models of 16- bit microcontrollers. These products feature on-chip flash memory that supports write and rewrite operations from a single-

voltage power supply. Sample shipments will begin in August 1997 in Japan.These two products operate from a 5-V single-voltage power supply, include 128kbytes of flash memory, and operate at the high speed of 20 MHz. As such, theycomputer peripherals such as CD-ROM and DVD drives and commercialequipment, and furthermore can contribute to shorter development periods andallow program changes even after end products are shipped.

The ability to reload microcontroller programs at all stages in the product cyclefrom development and prototyping through first production and then mass production, as well as field programmability for easy parameter adjustment, havecome to be strongly desired in the microcontrollers used in electronic equipment

to support the increasing scale of the software used in these products, to providereduced product development times, and to support product specificationimprovements and adjustments to the control data. The frequent changes to thesoftware due to constantly changing customer requirements and the release ofnew versions in commercial equipment and computer peripherals such as CD-ROM and DVD drives have resulted in strong needs for on-chip flash memorymicrocontrollers that allow on-board programming. The H8/3437F Series andH8/3337YF Series F-ZTAT(TM) microcontrollers have been widely used in suchapplications. However, the performance increases in CD-ROM drives have been phenomenal, and CPUs with performance that can support higher speed CD-ROMaccess are now required. Also, larger memory spaces are now required in DVD

drives.

To respond to these needs for increased performance and memory capacities,Hitachi has released the H8S/2134F (80-pin version) and the H8S/2144F (100-pinversion) of the H8S Series. These two new microcontrollers both include 128kbytes of single-voltage power supply flash memory on chip. These products arefabricated in a 0.5 micron CMOS process and include 128 kbytes of flash memoryand 4 kbytes of RAM on chip. Although it was previously necessary to provide an

external 12-V power supply for erasing and writing the flash memory thesemicrocontrollers achieve 5-V single-voltage power supply operation by includinga step-up circuit on chip, allowing the cost of the 12-V power supply to be savedin end products. The single-state execution of basic instructions(*2), which is afeature of the H8S Series, allows these microcontrollers to achieve 20-MHz

operation at 5 V, 10- MHz operation at 3 V, and at least twice the performance ofthe earlier H8/3337YF Series at about 1/5 the power dissipation.

These microcontrollers include four multifunction timers, an 8-input A/Dconverter, and three serial communications interface channels as peripheralfunctions. These microcontrollers are upward compatible with the H8/3337YFand can use the basic functions provided by earlier software, allowing users toeasily achieve improved performance and increased functionality in existing end product lines.

Additionally, due to the static circuit technology(*3) common to the H8S Series,

these microcontrollers provide high-level power saving functions, includingmedium speed modes in which the CPU and other clocks are switched to functionat rates from 1/2 to 1/32 that of the basic clock, a module stop function that allowsthe peripheral modules to be turned on or off individually, and a sleep mode. Thusthese products can provide the fine low-power mode control required by portableequipment.

The H8S/2134F and H8S/2144F differ in the number of I/O pins, with theH8S/2134F providing 66 pins and the H8S/2144F providing 82 pins. TheH8S/2134F is provided in an 80-pin plastic QFP package (with a 14 x 14-mm body and a 0.65-mm lead pitch) and an 80-pin plastic TQFP package (with a 12 x

12-mm body and a 0.5-mm lead pitch) and the H8S/2144F is provided in a 100- pin plastic QFP package (with a 14 x 14-mm body and a 0.5-mm lead pitch) and a100-pin plastic TQFP package (with a 14 x 14-mm body and a 0.5-mm lead pitch).

Future developments in this area will include mask ROM versions of theH8S/2134F and H8S/2144F, as well as new versions with differing memorycapacities. In particular Hitachi is developing an F-ZTAT(TM) version with 64kbytes of flash memory, and mask ROM versions with 64, 96, and 128 kbytes ofmask ROM. Additionally, Hitachi is planning to develop a version with improved personal computer communications functions and compact versions in 64-pin packages.

Note: 1. F-ZTAT(TM) (Flexible ZTAT) microcontroller Microcontrollers that provide flexibility in system development by providing on-chip flash memory to allow application software to be reloaded easily with themicrocontroller in the on-board state. F-ZTAT(TM) is a trademark of Hitachi,Ltd.

2. Single state execution of basic instructions The H8S CPU executes frequently-used instructions, such as register to registeroperations in a single state (clock cycle). This CPU reduces the number of cyclesrequired for instruction execution in the H8/300H CPU by 1/2 for essentially all(95%) instructions.

3. Static circuit Unlike dynamic circuits, which require both a precharge period and a discharge period, static circuits dispense with the precharge period and allow fasteroperation and reduced power consumption due to a reduction in the frequency ofsignal state changes. These circuits can retain their state even without a clock, andthus are effective for low-speed operation.

Application Product Examples: - CD-ROM drives, DVD drives, and other computer related equipment. Handy phone.

Features: 1. On-chip single-voltage power supply flash memory These microcontrollers do not need the external 12-V power supply required byearlier flash memory products for data erase and write operations. Also, they donot require a special tool for data writing and support on-board programming andreprogramming. This gives these microcontrollers the ability to reload application

software at all stages in the product cycle from development and prototypingthrough first production and then mass production, providing great flexibility overa wide range.

2. High-speed operation and low power consumption achieved These microcontrollers achieve 20-MHz operation at 5 V, 10-MHz operation at 3V, and at least twice the performance of the earlier H8/3337YF Series at about 1/5the power consumption.

3. Identical pin arrangement and upward compatibility with the H8/3337YF

(H8S/2134F) These two microcontrollers are upward compatible with the H8/3337YF Series,which has been widely used in computer-related and commercial equipment suchas CD-ROM drives. This allows existing software assets to be reused.

Additionally, the H8S/2134F adopts the same pin arrangement as the H8/3337YF,while the H8S/2144F adds an extra 16 I/O pins, allowing users to easily achieveincreased system functionality and performance.

4. Low-voltage and low-power operation achieved These microcontrollers provide a rich set of power saving functions, including amedium-speed mode, a sleep mode, and a module stop mode, and can efficientlyreduce system power consumption.

Development Environment: A user development environment that consists of the C compiler, assembler,

linkage editor, librarian, simulator, debugger and other tools already available forthe H8S series is available for these microcontrollers. Furthermore, these tools runon widely available personal computers and workstations. Additionally, theE6000 real-time emulator and other emulators are available as hardware support.
