RSKR8CLA8A RENESAS STARTER KIT R20UT0284EG0101 Rev.1.01 Jun 16, 2011 1. Overview 1.1 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. 1.
RSKR8CLA8A 2. Power Supply 2. Power Supply 2.1 Requirements This RSK is supplied with an E8a debugger. The debugger 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 and RSK+ boards have an optional centre positive supply connector using a 2.0mm barrel power jack. This RSK supports 5V and 3.3V inputs, and requires specific configuration for different inputs.

RSKR8CLA8A 5. User Circuitry 5. User Circuitry 5.1 Reset Circuit The RESET pin is connected to Board_VCC via a pull-up resistor R33. When the VCC pin voltage level rises, the power-on reset function is enabled and the pins, CPU, and SFRs are reset. Refer to the R8C/LA8A hardware manual for details regarding the reset signal timing requirements, and the RSK R8C/LA8A board schematics for information regarding the reset circuitry in use on the RSK. 5.
RSKR8CLA8A 5.4 5. User Circuitry LEDs There are five LEDs on the RSK board. The function of each LED, its colour, and its connections are shown in Table 5-3. LED Colour Function MCU Connection PWR Green Indicates the status of the Board_VCC power rail. No connection LED0 Green User operated LED. P6_1, Pin 74 LED1 Orange User operated LED. P6_2, Pin 73 LED2 Red User operated LED. P6_3, Pin 72 LED3 Red User operated LED. P6_4, Pin 71 Table 5-3: LED Connections 5.
RSKR8CLA8A 5.7 5. User Circuitry RS232 Serial Port Serial port UART0 is connected to the standard RS232 header fitted to the RSK. Alternatively, serial port UART2 can be connected to the RS232 transceiver by making changes to the configurations to the jumpers and option links (refer to §6). Connections between the RS232 header and the microcontroller are listed in the Table 5-5. SCI Signal Function MCU Connection RS232 Connection TxD0 UART0 Transmit Signal.
RSKR8CLA8A 6. Configuration 6. Configuration 6.1 Modifying the RSK This section lists the option links that are used to modify the way RSK operates in order to access different configurations. Configurations are made by modifying link resistors or headers with movable jumpers. A link resistor is a 0Ω surface mount resistor, which is used to short or isolate parts of a circuit. Option links are listed in the following sections, detailing their function when fitted or removed.
