Chapter 2. Purpose
This RSK is an evaluation tool for Renesas microcontrollers.
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.
Features include:
• Renesas Microcontroller Programming.
• User Code Debugging.
• User Circuitry such as Switches, LEDs and potentiometer.
• User or Example Application.
• Sample peripheral device initialisation code.
The RSK board contains all the circuitry required for microcontroller operation.

Chapter 3. Power Supply
3.1. Requirements
This RSK operates from a 5V power supply.
A diode provides reverse polarity protection only if a current limiting power supply is used.
All RSK boards are supplied with an E10A debugger.
All RSK boards have an optional centre positive supply connector using a 2.0mm barrel power jack.
Warning
The RSK is neither under nor over voltage protected. Use a centre positive supply for this board.
3.2. Power – Up Behaviour
When the RSK is purchased the RSK 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. After 200 flashes, or after pressing a switch the LEDs
will 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 RSK microcontroller is reset. RESn, Pin 91
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 E10A debugger.
SW2* Connects to an IRQ line for user controls. IRQ1n, Pin 85
SW3* Connects to the ADC trigger input. Option link allows connection to IRQ line.
The option is a pair of 0R links. For more details on option links, please refer
to Sec 6.6.
*Refer to schematic for detailed connectivity information.

6.2. LEDs
There are six LEDs on the RSK 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 channel AN0 (P5.0, pin 118) of the microcontroller. This may be used to vary the input analog
voltage value to this pin between AVCC and Ground.
6.4. Serial port
Serial port SCI0 is connected to the standard RS232 header. Serial port SCI5 can optionally be connected to the RS232 header. The
connections to be fitted are listed in the Table 6-3.
