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 E10A debug module and a PSU. 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. Weher

possible use the supplied PSU.

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 any switch will cause the LEDs to flash at a rate controlled by the potentiometer.

Chapter 4. Board Layout

4.1. Component Layout

The following diagram shows top layer component layout of the board.

4.2.Board Dimensions

The following diagram gives the board dimensions and connector positions. All through hole connectors are on a common 0.1” grid for easy interfacing.

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, Pin 2

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.

SW2* Connects to an IRQ line for user controls. IRQ1 , Pin 58

SW3* Connects to an IRQ line for user controls. Also connects to the ADC

trigger input. The option is a pair of 0R links. For more details on option links, please refer to

*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. This may be used to vary the input analog voltage value to this pin between AVCC and Ground.
