Chapter 3. Power Supply

3.1. Requirements

This CPU board operates from a 5V power supply.

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

The kit is supplied with an E10A debug module and a PSU. When the CPU board is connected to another system that system should

supply power to the CPU board.

All CPU boards have an optional centre positive supply connector using a 2.0mm barrel power jack which is compatible with the supplied

PSU.

Warning

The CPU board is neither under not over voltage protected. Use a centre positive supply for this board.

3.2. Power – Up Behaviour

When the RSK is purchased the CPU 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. Pressing any switch will cause the LEDs to flash at a

rate controlled by the potentiometer.
