Chapter 2. Purpose
This RSK is an evaluation tool for Renesas microcontrollers.
Features include:
• Renesas Microcontroller Programming.
• User Code Debugging.
• User Circuitry such as switches, LEDs and potentiometer(s).
• Sample Application.
• Sample peripheral device initialisation code.
The CPU board contains all the circuitry required for microcontroller operation.
This manual describes the technical details of the RSK hardware. The Quick Start Guide and Tutorial Manual provide details of the
software installation and debugging environment.

Chapter 3. Power Supply
3.1. Requirements
This CPU board operates from a 5V power supply.
A diode provides reverse polarity protection only if a current limiting power supply is used.
All CPU boards are supplied with an E8 debugger. This product is able to power the CPU board with up to 300mA. When the CPU board is
connected to another system, that system should supply power to the CPU board.
All CPU boards have an optional centre positive supply connector using a 2.0mm barrel power jack.
Warning
The CPU board is neither under not over voltage protected. Use a centre positive supply for this board.
3.2. Power – Up Behaviour
When the RSK is purchased the CPU board has the ‘Release’ or stand alone code from the example tutorial code pre-programmed into the
Renesas microcontroller. On powering up the board the user LEDs will start to flash. Pressing switch 2 will cause the LEDs to flash at a rate
controlled by the potentiometer.

Chapter 6. User Circuitry
6.1. Switches
There are four switches located on the CPU board. The function of each switch and its connection are shown in Table 6-1.
Switch Function Microcontroller
RES When pressed; the CPU board microcontroller is reset. RESn
SW1/BOOT* Connects to an IRQ input for user controls.
The switch is also used in conjunction with the RES switch to place
the device in BOOT mode when not using the E8 debugger.
SW2* Connects to an IRQ line for user controls. IRQ2n , Pin 87
SW3* Connects to the ADC trigger/ IRQ3 input via option 0R link R105. IRQ3n, Pin 83
Table 6-1: Switch Functions
*Refer to schematic for detailed connectivity information.

6.2. LEDs
There are six LEDs on the CPU board. The green ‘POWER’ LED lights when the board is powered. The orange BOOT LED indicates the
device is in BOOT mode when lit. The four user LEDs are connected to an IO port and will light when their corresponding port pin is set low.
Table 6-2, below, shows the LED pin references and their corresponding microcontroller port pin connections.

6.3. Potentiometer
A single turn potentiometer is connected to AN0 of the microcontroller via R42. This may be used to vary the input analog voltage value to
this pin between AVCC and Ground.
6.4. Serial port
The microcontroller programming serial port (SCI2) is connected to the E8 connector by default. SCI0 is connected to the 9-way D-type
connector labelled J8 via a RS232 transceiver.
10
The microcontroller programming serial port can optionally be disconnected from the E8 and connected to the RS232 transceiver by
moving option resistors. Serial channel 0 is then disconnected. The connections to be moved are listed in the following table.

Table 6-3 - Serial Option Links
The board is designed to accept a straight through RS232 cable. A secondary microcontroller serial port is available and connected to the
application headers. Please refer to the schematic diagram for more details on the available connections.
6.5. LCD Module
A LCD module can be fitted to the LCD connector. Any module that conforms to the pin connections and has a KS0066u compatible
controller can be used with the tutorial code. The LCD module uses a 4bit interface to reduce the pin allocation. No contrast control is
provided; this must be set on the display module.
Table 6-4 shows the pin allocation and signal names used on this connector.
The module supplied with the CPU board only supports 5V operation.
