To our customers,
Old Company Name in Catalogs and Other Documents
On April 1st, 2010, NEC Electronics Corporation merged with Renesas Technology
Corporation, and Renesas Electronics Corporation took over all the business of both
companies. Therefore, although the old company name remains in this document, it is a valid
Renesas Electronics document. We appreciate your understanding.

Chapter 2.Purpose
This RSK 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 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 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 2.0mm 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.

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 E8A debugger.
SW2* Connects to an IRQ line for user controls. IRQ2n, Pin 53
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

A single turn potentiometer is connected to AN4 (PB.4) 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 SCI3 is connected to the standard RS232 header. Serial port SCI3_2 can optionally be connected to the RS232. The
connections to be fitted are listed in the table 6-3.

The SCI3_2 port is also available on J4 and JA2. The SCI3 port is available on J3.
6.5. 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 J1.
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 6-6: Oscillators / Resonators
6.8. 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 port pin P24 states as required.
The port pin P24 must 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 by a pair of resistors and a capacitor. Please check the reset requirements carefully
to ensure the reset circuit on the user’s board meets all the reset timing requirements.
13
Chapter 7. Modes
This RSK supports Boot mode and User mode.
Details of programming the FLASH memory is described in the H8/38347 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:
TEST NMI P85 LSI State after Reset End
0 Low High Boot Mode
Table 7-1: Boot Mode pin settings
The software supplied with this RSK supports Boot mode using an E8A and HEW only. However, hardware exists to enter boot mode
manually, do not connect the E8A in this case. Press and hold the SW1/BOOT. The pin NMI (microcontroller pin 35) is held in its boot state
while reset is pressed and released. Release the boot button. The BOOT LED will be illuminated to indicate that the microcontroller is in
boot mode.
When neither the E8A is connected nor the board is placed in boot mode as above, the TEST pin is connected to Ground; the NMI pin is
pulled high by a 10k resistor, the P8.5 pin is pulled high with a 4.7k resistor.
When an E8A is used the port P85 and NMI are controlled by the E8A.
7.2. User mode
Because the NMI pin is pulled high, this RSK will always boot in User mode when the E8A is not connected and the boot switch is not
depressed. Refer to H8/36079 Group Hardware Manual for details of User 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 E8A. An E8A pod
is supplied with the RSK product.
10.2. Mode Support
HEW connects to the Microcontroller and programs it via the E8A. Mode support is handled transparently to the user.
10.3. 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.
