Chapter 2. Purpose

This Renesas Starter Kit is an evaluation tool for Renesas microcontrollers. Features include:

• Renesas Microcontroller Programming.

• User Code Debugging.

• User Circuitry such as Switches, LEDs and potentiometer(s).

• User or Example Application.

• Sample peripheral device initialisation code.

The Renesas Starter Kit board contains all the circuitry required for microcontroller operation.

Chapter 3. Power Supply

3.1. Requirements

This Renesas Starter Kit operates from a 3V to 5V power supply. A diode provides reverse polarity protection only if a current limiting power supply is used. All Renesas Starter Kit boards are supplied with an E8a debugger. This product is able to power the Renesas Starter Kit board with up to

300mA. When the Renesas Starter Kit is connected to another system then that system should supply power to the Renesas Starter Kit. All Renesas Starter Kit boards have an optional centre positive supply connector using a 2.1mm barrel power jack.

Warning

The Renesas Starter Kit is neither under nor over voltage protected. Use a centre positive supply for this board.

3.2. Power – Up Behaviour

When the Renesas Starter Kit is purchased the Renesas Starter Kit 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 board. The function of each switch and its connection are shown in Table 6-1.

Switch Function Microcontroller

RES When pressed, the board microcontroller is reset. RESETn Pin9 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 E8A debugger.

SW2* Connects to an IRQ Interrupt input line for user controls. INT1n Pin52

SW3* Connects to a Key In Interrupt input line for user controls INT2n Pin53

Table 6-1: Switch Functions

*Refer to schematic for detailed connectivity information.

INT0n Pin44 (Port 4, pin 5)

(Port 3, pin 6)

(Port 3, pin 2)

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 AN8 (P1.0) of the microcontroller. This may be used to vary the input analog voltage value to this pin between VREF and Ground.
