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 • Sample Application. • Sample peripheral device initialisation code.
Chapter 3. Power Supply 3.1. Requirements This RSK board operates from a 5V DC power supply. A diode provides reverse polarity protection only if a current limiting power supply is used. All RSK boards are supplied with an E8a debugger. This product is able to power the RSK board with up to 300mA. When the RSK is connected to another system then that system should supply power to the RSK. All RSK boards have an optional centre positive supply connector using a 2.1mm barrel power jack.
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.

Chapter 6. User Circuitry 6.1. Switches There are four switches located on the RSK board. The function of each switch and its connection are shown in Table 6-1 Switch Function Microcontroller RES When pressed, the microcontroller is reset. RESETn, Pin 9 SW1 / BOOT* Connects to an INT input for user controls. INT1n, Pin 35 (Port 3, bit 6) The switch is also used in conjunction with the RES switch to place the device in BOOT mode when not using the E8a debugger.
6.4. Serial port Serial port UART2 is connected to the standard RS232 header. Serial port UART0 can optionally be connected to the RS232 transceiver by moving option resistors. The connections to be moved are listed in the Table 6-3.
6.6. LIN The serial port UART0 also functions as LIN port pins. The options links to be configured are listed in the Table 6-5 Description Function Circuit Net Name Device Pin Fit for Hardware Remove for LIN Hardware LIN LIN TXD LINTXD 52 R70 R71 LIN RXD LINRXD 51 R72 R73 LIN NSLP LINNSLP 50 R74 R75 Table 6-5: Hardware LIN Settings For more details regarding configuring the RSK to operate in LIN master and slave mode, refer to table 6-6.

Table 6-11 below describes miscellaneous options links.
Chapter 7. Modes The Renesas Starter Kit supports Boot mode and Single chip mode. Details of programming the FLASH memory is described in the R8C/38C Group Hardware Manual. This circuit is not required on customer’s boards as it is intended for providing easy evaluation of the operating modes of the device on the RSK. To manually enter the Boot mode, press and hold the SW1/BOOT. The mode pins are held in their boot states while reset is pressed and released. Release the boot button.
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/38C Group Hardware Manual for details of Single chip mode.
Chapter 8. Programming Methods The board is intended for use with HEW and the supplied E8a debugger. Refer to R8C/38C Group Hardware Manual for details of programming the microcontroller without using these tools.
Chapter 9. Headers 9.1. Microcontroller Ring Headers The microcontroller pin headers and their corresponding microcontroller connections are detailed in Table 9-1 to Table 9-4.
