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.
The switch is also used in conjunction with the RES switch to place the device in
BOOT mode when not using the E10A debugger.
SW2* Connects to an IRQ line for user controls. IRQ1, Pin 45
SW3* Connects to the ADC trigger input. Option link allows connection to IRQ line.
The option is a pair of 0R links. For more details on option links, please refer
to Sec 6.6.
*Refer to schematic for detailed connectivity information.

IRQ2, Pin 44
(Port B, pin 4)
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.

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.

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.

6.8. Oscillator Sources
A crystal oscillator is fitted on the RSK and used to supply the main clock input to the Renesas microcontroller. Table 6-15 details the
oscillators that are fitted and alternative footprints provided on this RSK:

Crystal (X1) Fitted 10 MHz (HC49/4H package)
Table 6-15: Oscillators / Resonators
6.9. Reset Circuit
The CPU Board includes a simple latch circuit that links the mode selection and reset circuit. This provides an easy method for swapping
the device between Boot Mode and User mode. 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. Please refer to the hardware manual for more information on the
requirements of the reset circuit.
The Reset circuit operates by latching the state of the boot switch on pressing the reset button. This control is subsequently used to
modify the mode pin states as required.
The mode pins should change state only while the reset signal is active to avoid possible device damage.
The reset is held in the active state for a fixed period via a resistor/capacitor delay circuit. Please check the reset requirements carefully
to ensure the reset circuit on the user’s board meets all the reset timing requirements.

Chapter 7. Modes
This RSK supports Boot mode, User Boot mode, User Program Mode and User mode.
Details of programming the FLASH memory is described in the SH2/7137 Group Hardware Manual.
7.1. Boot mode
The boot mode settings for this RSK are shown in Table 7-1: Boot Mode pin settings below:
FWE MD2n MD1 LSI State after Reset End

Table 7-1: Boot Mode pin settings
The software supplied with this RSK supports debugging with E10A which does not need Boot mode. To enter the Boot mode manually, do
not connect the E10A in this case. Press and hold the SW1/BOOT. The BOOT LED will be illuminated to indicate that the microcontroller is
in boot mode.

Chapter 10. Code Development
10.1. Overview
Note: For all code debugging using Renesas software tools, the RSK board must be connected to a PC USB port via an E10A. An E10 A
pod is supplied with the RSK product.
10.2. Compiler Restrictions
The compiler supplied with this RSK is fully functional for a period of 60 days from first use. After the first 60 days of use have expired, the
compiler will default to a maximum of 256K code and data. To use the compiler with programs greater than this size you need to purchase
the full tools from your distributor.
Warning: The protection software for the compiler will detect changes to the system clock. Changes to the system clock back in time may
cause the trial period to expire prematurely.
10.3. Mode Support
HEW connects to the Microcontroller and programs it via the E10A. Mode support is handled transparently to the user.
10.4. Breakpoint Support
HEW supports breakpoints on the user code, both in RAM and ROM.
Double clicking in the breakpoint column in the code sets the breakpoint. Breakpoints will remain unless they are double clicked to remove
them.
