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. • 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 5V power supply. A diode provides reverse polarity protection only if a current limiting power supply is used. This Renesas Starter Kit board is 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. 3.81 5.00 45.00 14.00 JA1 39.37 52.07 67.31 77.47 85.00 92.71 100.00 J4 J1 MCU J3 J2 JA2 27.00 27.94 38.10 50.80 53.34 73.66 80.00 85.
Chapter 5. Block Diagram Figure 5-1 is representative of the CPU board components and their connectivity.
Figure 5-2 is representative of the connections required to the Renesas Starter Kit.
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, Pin8 SW1/BOOT* Connects to an IRQ input for user controls. INT1n, Pin31 The switch is also used in conjunction with the RES switch to place (Port 1, pin 7) the device in BOOT mode when not using the E8a debugger.
6.4. Serial port Serial port UART0 and serial port UART1 are connected to the RS232 transceiver. These serial ports can optionally be connected to the RS232 transceiver as well by fitting option resistors. The connections are listed in the Table 6-3.
6.6. Debug 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 J4. Care should be taken to ensure the pins are inserted correctly into LCD. 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 6-8 below describes the function of the option links associated with Clock configuration. The default configuration is indicated by BOLD & Red text. Option Link Settings Reference R1 R2 Function Fitted Alternative (Removed) 20MHz Main Clock Parallel resistor for on-board Oscillator main clock X1.
Table 6-9 below describes the function of the option links associated with Analog configuration. The default configuration is indicated by BOLD & Red text.
Table 6-10 below describes the function of the option links associated with application board interface configuration. The default configuration is indicated by BOLD & Red text. Option Link Settings Reference R56 R57 R58 R59 R60 R61 R70 R71 R72 R73 R74 R75 Function Fitted Alternative (Removed) Application Board Connects DA0 to MCU Interface Port0.6 (MCU Pin#40) Application Board Connects IO6 to MCU Port0.6 Interface (MCU Pin#40) Application Board Connects DA1 to MCU Interface Port0.
Table 6-11 below describes the function of the option links associated with other options. The default configuration is indicated by BOLD & Red text. Option Link Settings Reference R30 Function SW1 Fitted Alternative (Removed) Connects SW1 to MCU Related To Disconnected - Disconnected - Disconnected - Do not remove resistor R50 - Port1.7 (MCU Pin#31) R31 SW2 Connects SW2 to MCU Port6.6 (MCU Pin#28) R32 SW3 Connects SW3 to MCU Port4.
6.8.Oscillator Sources Crystal oscillators are fitted on the board and used to supply the main/sub clock input to the Renesas microcontroller. Table 6-12 details the oscillators that are fitted and alternative footprints provided on this board: Component Main clock (X1) Fitted 20 MHz (HC/49U package) Sub clock (X2) Fitted 32.768 kHz (90SMX package) Table 6-12: Oscillator 6.9.Reset Circuit The CPU Board includes a simple latch circuit that links the mode selection and reset circuit.
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/35C Group Hardware Manual. 7.1. Boot mode The Boot mode settings for this Renesas Starter Kit are shown in Table 7-1 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.
Chapter 8. Programming Methods The board is intended for use with High-performance Embedded Workshop and the supplied E8a debugger. Refer to R8C/35C 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 pin unless otherwise stated.
