7. Renesas Electronics products are classified according to the following three quality grades: “Standard”, “High Quality”, and

“Specific”. The recommended applications for each Renesas Electronics product depends on the product’s quality grade, as indicated below. You must check the quality grade of each Renesas Electronics product before using it in a particular application. You may not use any Renesas Electronics product for any application categorized as “Specific” without the prior written consent of Renesas Electronics. Further, you may not use any Renesas Electronics product for any application for which it is not intended without the prior written consent of Renesas Electronics. Renesas Electronics shall not be in any way liable for any damages or losses incurred by you or third parties arising from the use of any Renesas Electronics product for an application categorized as “Specific” or for which the product is not intended where you have failed to obtain the prior written consent of Renesas Electronics. The quality grade of each Renesas Electronics product is “Standard” unless otherwise expressly specified in a Ren esas E lectronics data sheets or dat a books, etc.

“Standard”: Computers; office equipment; communications equipment; test and measurement equipment; audio and visual

equipment; home electron ic appliances; machine tools; personal electronic equipment; and industrial robots.

Glossary

CPU Central Processing Unit HEW High-performance Embedded Workshop LED Light Emitting Diode RSK Renesas Starter Kit PC Program Counter E10A On-chip debugger module for starter kits LCD Liquid Crystal Display RCAN Renesas Controller Area Network

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 70(*) 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. IRQ1, Pin 45

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.

(Port B, pin 3) IRQ2, Pin 44 (Port B, pin 4)

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 AN8 (PF8) of the microcontroller. This may be used to vary the input analogue voltage value to this pin between AVCC and Ground.

6.4. Serial port

Serial port SCI2 is connected to the standard RS232 header. Serial port SCI0 can optionally be connected to the RS232 header. The connections to be fitted are listed in the Table 6-3.

6.6. Debug LCD Module

A debug LCD module is supplied to be connected to the connector LCD. This should be fitted so that the debug LCD module lies over J3. Care should be taken to ensure the pins are inserted correctly into LCD. The debug LCD module uses a 4 bit interface to reduce the pin allocation. No contrast control is provided; this is set by a resistor on the supplied display module. The module supplied with the RSK only supports 5V operation.

Table 6-5 shows the pin allocation and signal names used on this connector.
