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.

•User or Example Application.

•Sample peripheral device initialisation code.

The RSK board contains all the circuitry required for microcontroller operation.

Chapter 3. Power Supply

3.1. Requirements

This RSK operates from a 5V power supply.

A diode provides reverse polarity protection only if a current limiting power supply is used.

All RSK boards are supplied with an E10A debugger.

All RSK boards have an optional centre positive supply connector using a 2.0mm barrel power jack.

Warning

The RSK is neither under nor over voltage protected. Use a centre positive supply for this board.

3.2. Power – Up Behaviour

When the RSK is purchased the RSK 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.

Chapter 6. User Circuitry

6.1. Switches

There are four switches located on the CPU board. The function of each switch and its connection are shown in Table 6-1.

Switch	Function	Microcontroller
RES	When pressed, the RSK microcontroller is reset.	RESn, Pin 70(*)

SW1/BOOT*	Connects to an IRQ input for user controls.	IRQ0, Pin 46
	The switch is also used in conjunction with the RES switch to place the device in	(Port B pin 2)
	BOOT mode when not using the E10A debugger.

SW2*	Connects to an IRQ line for user controls.	IRQ1, Pin 45
		(Port B, pin 3)

SW3*	Connects to the ADC trigger input. Option link allows connection to IRQ line.	IRQ2, Pin 44
	The option is a pair of 0R links. For more details on option links, please refer	(Port B, pin 4)
	to Sec 6.6.

	Table 6-1: Switch Functions

*Refer to schematic for detailed connectivity information.

6.2. LEDs

There are six LEDs on the RSK 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.

LED Reference (As		Colour	Microcontroller Port Pin	Microcontroller
shown on silkscreen)				Pin Number
LED0	Green		Port D0	40

LED1	Orange		Port D1	38

LED2	Red		Port D2	37

LED3	Red		Port D3	35

Table 6-2: LED Port

6.3. Potentiometer

A single turn potentiometer is connected to channel AN8 (PF8) of the microcontroller. This may be used to vary the input analogue voltage value to this pin between AVCC and Ground.

6.4. Serial port

Serial port SCI2 is connected to the standard RS232 header. Serial port SCI0 can optionally be connected to the RS232 header. The connections to be fitted are listed in the Table 6-3.

Description	Function	Microcontroller	Fit for RS232	Remove for RS232
		Port Pin
SCI2	Default serial port	58	R30	R53

SCI2	Default serial port	60	R39	R54

SCI0	Spare Serial Port	68	R53	R30

SCI0	Spare Serial Port	69	R54	R39

Table 6-3: Serial Port settings

The SCI2 port is also available on J3 and JA6. The SCI0 port is available on J3 and JA2.

6.5. RCAN-ET

The RCAN module can be used for RCAN communication.

Table 6-4 contains details of the signal descriptions and pin connections.

Description	Function	Microcontroller Pin	Header Pins
		Number
CTx0	Transmit data input	42	J2-12

CRx0	Receive data output; reads out data	41	J2-11
	from the bus lines

CAN_EN	Enable control input	49	J2-19

CAN_ERRn	Error and power-on indication output	63	J3-13

CAN_STBn	Standby control input	43	J2-13

Table 6-4: CAN module settings

6.6. Debug LCD Module

A debug LCD module is supplied to be connected to the connector LCD. This should be fitted so that the debug LCD module lies over J3. Care should be taken to ensure the pins are inserted correctly into LCD. The debug 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 RSK only supports 5V operation.

Table 6-5 shows the pin allocation and signal names used on this connector.

LCD

Pin	Circuit Net Name	Device	Pin	Circuit Net Name	Device
		Pin			Pin
1	Ground	-	2	5V Only	-
3	No Connection	-	4	DLCDRS (PD10)	28
5	R/W (Wired to Write only)	-	6	DLCDE + 100k pull down to ground (PD9)	29
7	No Connection	-	8	No connection	-
9	No Connection	-	10	No connection	-
