Chapter 3 Features

3.1 Power Supply The board can be powered from the USB VBUS power through a USB cable. In this case, no external power supply is required. If the VBUS power voltage or current draw is not sufficient for the application, connect a stable power supply to the power expansion PCN terminal.

3.1.1 Power Circuit Configuration

* : PCN does not have a connector.


3.1.2 Power Supply Methods There are two ways to supply power.

① Power the board through a USB cable

Connect the board to the PC through a USB cable.

If the VBUS power voltage is not sufficient for the application, or if the current draw exceeds 500mA, use an external power supply.

② Power the board from an external power supply through the PCN terminal

Connect a DC5V external power supply to the PCN terminal. No. Power 1 GND 2 DC5V

* : PCN does not have a connector. "B2P-SHF-1AA" (JST) can be attached.

Note Note


3.2 Reset When the board is connected through a USB cable or is powered by an external power supply, a reset occurs. The reset starts when the 3.3V (VCC) power supply reaches approximately 3.125V at power-on. The reset outputs a LOW pulse for approximately 34 ms using the specialized "RNA51957BFP" IC. When the LOW pulse ends and a HIGH pulse begins, the CPU starts the power-on reset.

3.3 Boot Mode The CPU is set in boot mode 1. It is booted from the serial flash memory connected to the SPI multi-I/O bus space. The U-Boot program is preloaded into the serial flash memory by default.

3.5 Serial Flash Memory The board incorporates 2MB of serial flash memory. It is connected to the CPU SPI interface and is set as part of serial flash boot (CPU boot mode 1). The U-Boot program loaded into serial flash memory is booted after power-on. U-Boot is preloaded by default. When U-Boot is run, the board is customized.

Note that, if you delete the U-Boot program loaded into serial flash memory, the board itself cannot restore it. A debugger is required to re-load the program.

3.6 SDRAM

The board incorporates 32MB of SDRAM. It is connected to the CPU through the 16-bit bus.

Note Note


3.7 EEPROM The board has a 1Kbit EEPROM for saving parameters. It can be used to save network settings and parameters. The Ethernet MAC address is stored in EEPROM by default, and a sticker on which the address is recorded is attached to the board. You can use the MAC address assigned by IEEE. If you change the MAC address, use the address that you acquire.

3.8 Serial Interface The serial interface on the board is connected through the USB-to-Serial converter IC from the USB2.0 mini-B connector (USB_FCN). Channel 3 is used for the CPU serial function.

USB_FCN


3.9 USB Host Interface The board has a USB host connector (USB_HCN). Channel 0 is used for the CPU USB function. The VBUS power output is supplied by turning the power on by using the CPU port.

3.11 Sensors The board has a temperature sensor connected through Smart Analog. Temperature can be measured from the data read by the A/D converter of the CPU. You can install a humidity sensor on the board and also use other sensors by connecting them to Smart Analog expansion terminal SA_EXTCN. A sensor expansion board is also available to allow the user to connect sensors other than those on the board. Such sensors could include pyroelectric sensors, gas sensors, and current transformer sensors.

3.11.1 Smart Analog Smart Analog is a Renesas Electronics analog IC that allows the user to change the circuit configuration and its properties through software setting. For more information, go to the Renesas Electronics homepage.

3.11.2 SA_EXTCN Some Smart Analog signals are connected to expansion terminal SA_EXTCN. Use this terminal when you expand the connection. The expansion terminal pins are on a 2.54-mm pitch.

*1：0PD : Pull-down processing is performed with the 0-Ω resistor. The figures in the parenthesis are the references for the pull-down resistance.

*2：Unused Smart Analog terminals are connected to the analog GND through the 0-Ω resistor. If you use them for expansion, remove the resistor.


3.11.3 Temperature Sensor The board has a thermistor. The resistance of a thermistor changes with temperature. Based on this property, temperature can be measured by measuring the voltage change in the CPU A/D converter. VCC uses the 1-V voltage output from Smart Analog. From the voltage value of this VCC that is partially suppressed by the thermistor and resistor R105, the temperature is measured. The value is output to the CPU after being amplified by Smart Analog.

Smart Analog Register Settings To enable the use of the temperature sensor circuit, the Smart Analog registers must be set as follows:

PC1 0 0 0 1 0 0 0 1 11h


3.11.4 Humidity Sensor The board has a base pattern for installing humidity sensor "CHS-GSS" (TDK). The sensor is not installed by default. The customer is asked to provide this if required. The sensor VOUT indicates 100%RH with a 1V DC output. This value is output to the CPU through Smart Analog. If the sensor output is directly input to the CPU, CHS-GSS has an output impedance of 200 kΩ, which is higher than the CPU specifications with an allowable signal source impedance of Max 5 kΩ for analog input terminals. This may not guarantee the accuracy of the A/D converter, resulting in an incorrect measurement. Therefore, use Smart Analog with a low output impedance as the buffer amplifier.

Humidity sensor "CHS-GSS" requires a power supply of 4.75 V to 5.25 V. The USB VBUS power cannot satisfy this requirement. Therefore, connect a stable 5V DC power supply to the power expansion PCN terminal.

Smart Analog Register Settings To enable the use of the humidity sensor circuit, the Smart Analog registers must be set as follows:

Data Address Register

3.13 LCD Interface The board incorporates terminal LCD_CN which provides LCD function terminals. Use this to expand the LCD connection.

You cannot use the LCD and LAN simultaneously because the CPU LCD function terminal is a multifunctional terminal that is multiplexed with the LAN function terminal. By default, the LCD terminal is connected to the LAN-related components by the chip resistance. When using the LCD expansion terminal, you must change the on-board chip resistance.
