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.
Chapter 4. Board Layout 4.1. Component Layout The following diagram shows the 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. 45.00mm JA1 14.00mm MCU JA2 27.00mm 50.80mm 80.00mm 85.

Chapter 6. User Circuitry 6.1. Switches There are four switches located on the Renesas Starter Kit. 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. RESET Pin 7 SW1/BOOT* Connects to an IRQ input for user controls. INT0 Pin14 The switch is also used in conjunction with the RES switch to place (Port 8, pin 3) the device in BOOT mode when not using the E8a debugger.
6.3. Potentiometer A single turn potentiometer is connected to AN2.4 (P9.3) 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 The microcontroller programming serial port 1 is connected to the E8a connector. This serial port can optionally be connected to the RS232 transceiver as well by fitting zero Ohm option resistors and fitting the D connector. In addition the RS232 transceiver should be enabled.
6.6.Option Links Table 6-5 below describes the function of the option links associated with Power configuration. The default configuration is indicated by BOLD text.
Table 6-6 below describes the function of the option links associated with Clock configuration. The default configuration is indicated by BOLD text.
Table 6-8 below describes the function of the option links associated with Analog configuration. The default configuration is indicated by BOLD text.
Table 6-10 below describes the function of the option links associated with other options. The default configuration is indicated by BOLD text.
6.7.Oscillator Sources A crystal oscillator or ceramic resonator is fitted on the Renesas Starter Kit and used to supply the main clock input to the Renesas microcontroller. A crystal oscillator is fitted on the Renesas Starter Kit and used to supply the sub clock input.
Chapter 7. Modes The Renesas Starter Kit supports Boot mode and Single chip mode. Details of programming the FLASH memory is described in the M16C/26A Group Hardware Manual. 7.1.
Chapter 8. Programming Methods The board is intended for use with High-performance Embedded Workshop and the supplied E8a debugger. Refer to M16C/26A Group Hardware Manual for details of programming the microcontroller without using these tools.
Chapter 9. Headers 9.1. Microcontroller Headers Table 9-1 to Table 9-4 show the microcontroller pin headers and their corresponding microcontroller connections. The header pins connect directly to the microcontroller pins. * Marked pins are subject to option links.

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 Personal Computer USB port via an E8a. An E8a is supplied with the Renesas Starter Kit product. 10.2. Mode Support High-performance Embedded Workshop connects to the Microcontroller and programs it via the E8a. Mode support is handled transparently to the user. 10.3.
