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(s).
•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 2.1mm 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
WhentheRSKispurchasedtheRSKboardhasthe‘Release’orstand alone code from the exampletutorialcodepre-programmedintothe
Renesasmicrocontroller. On powering up theboard theuser LEDswill startto flash. After 200 flashes,or afterpressing a switchthe LEDs
will flash at a rate controlled by the potentiometer.

A crystal oscillator is fitted on the RSK and used to supply the main clock input to the Renesas microcontroller. details theTable 6-7
oscillators that are fitted and alternative footprints provided on this RSK:

Crystal (X1) Fitted 10MHz (HC/49U
package)
Subclock (X2) Fitted 32.768kHz (90SMX
package)
Table 6-7: 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, User Boot Mode and User mode. This circuit is not required on customers 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 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.

Chapter 7. Modes
The RSK supports Boot mode and Single chip mode.
Details of programming the FLASH memory is described in the M32C/87 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:
CNVSS P5.0 P5.5 LSI State after Reset
End

Boot Mode
Table 7-1: Boot Mode pin settings
The software supplied with this RSK only supports Boot mode using an E8a and HEW. However, hardware exists to enter boot mode
manually, do not connect the E8a in this case. Press and hold the SW1/BOOT. The mode pins above are held in their boot states 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 (with CNVSS and P5.5 being pulled low during reset) as above,
the P5.5 pin is pulled highby a 10k resistor, theP.5.0 pin is pulled high bya 100k resistor and the CNVSSis pulled low by a 100kresistor.
When an E8a is used these three pins are controlled by the E8a.
