To our customers,
Old Company Name in Catalogs and Other Documents
On April 1st, 2010, NEC Electronics Corporation merged with Renesas Technology
Corporation, and Renesas Electronics Corporation took over all the business of both
companies. Therefore, although the old company name remains in this document, it is a valid
Renesas Electronics document. We appreciate your understanding.

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.

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.

6.4. Serial port
This RSK provides two serial ports to the user. The serial port 1 has already been configured for use. To use serial port 2 the user needs to
configure the option links as given in
Table 6-3.

6.5. LCD Module
A LCD module is supplied to be connected to the connector ‘LCD’. This should be fitted so that the LCD module lies over ‘JA1’ and ‘JA5’.
Care should be taken to ensure the pins are inserted correctly into ‘LCD’ connector. The 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
Renesas Starter Kit only supports 5V operation.
Table 6-4 shows the pin allocation and signal names used on this connector.

Crystal (X1) Fitted 20 MHz (HC/49U package)
Sub clock (X2) Fitted 32.768 kHz (90SMX package)
Table 6-10: Oscillator Configuration
6.8. Reset Circuit
The CPU Board includes a simple latch circuit that links the mode selection and reset circuit. This provides an easy method for swapping
the device between Boot Mode and Single chip mode. This circuit is not required on customers’ boards as it is intended for providing
easy evaluation of the operating modes of the device on the Renesas Starter Kit. Please refer to the hardware manual for more
information on the requirements of the reset circuit.
11
The Reset circuit operates by latching the state of the boot switch on pressing the reset button. This control is subsequently used to
modify the mode pin states as required.
The MODE pin should change state only while the reset signal is active to avoid possible device damage.
The reset is held in the active state for a fixed period by a pair of resistors and a capacitor. Please check the reset requirements carefully
to ensure the reset circuit on the customers’ board meets all the reset timing requirements.
6.9. LIN Interface
This Renesas Starter Kit has hardware LIN interface. The interface is available on connector ‘LIN’. The connector ‘J5’ functions as power
connector for LIN. The device can be operated either in ‘Master’ mode or ‘Slave’ mode. The device performs LIN communication in
cooperation with Timer RA and UART0.
For more details on LIN interface please refer to R8C/2C Group, R8C/2D Group Hardware Manual.
12
Chapter 7. Modes
This Renesas Starter Kit supports Boot mode and Single chip mode.
Details of programming the FLASH memory is described in the R8C/2C Group, R8C/2D Group Hardware Manual.
7.1. Boot mode
The Boot mode settings for this Renesas Starter Kit are shown in Table 7-1: Boot Mode pin settings below:
MODE LSI State after Reset End
Low Boot Mode
Table 7-1: Boot Mode pin settings
The software supplied with this Renesas Starter Kit supports Boot mode using an E8a and High-performance Embedded Workshop only.
However, hardware exists to enter boot mode manually, do not connect the E8a in this case. Press and hold the SW1/BOOT. The mode pin
is held in its boot state while reset is pressed and released. Release the boot button. The BOOT LED will be illuminated to indicate that the
microcontroller is in boot mode.
When neither the E8a is connected nor the board is placed in boot mode as above, the MODE pin is pulled high by a 4.7k resistor.
When an E8a is used the MODE pin is controlled by the E8A.
7.2. Single chip mode
Because the MODE pin is pulled high, this Renesas Starter Kit will always boot in Single chip mode when the E8a is not connected and the
boot switch is not depressed. Refer to R8C/2C Group, R8C/2D Group Hardware Manual for details of Single chip mode.

Chapter 8. Programming Methods
The board is intended for use with High-performance Embedded Workshop and the supplied E8a debugger. Refer to R8C/2C Group,

Chapter 10. Code Development
10.1. Overview
Note: For all code debugging using Renesas software tools, the Renesas Starter Kit board must be connected to a PC USB port via an
E8a. An E8a is supplied with the Renesas Starter Kit product.
10.2. Mode Support
High-performance Embedded Workspace connects to the Microcontroller and programs it via the E8a. Mode support is handled
transparently to the user.
10.3. Breakpoint Support
High-performance Embedded Workshop supports breakpoints on the user code, both in RAM and ROM.
Double clicking in the breakpoint column in the code sets the breakpoint. Breakpoints will remain unless they are double clicked to remove
them.
