Chapter 3. Power Supply
3.1. Requirements
This Renesas Starter Kit operates from a 3V to 5V power supply.
A diode provides reverse polarity protection only if a current limiting power supply is used.
All Renesas Starter Kit boards are supplied with an E8a debugger. This product is able to power the Renesas Starter Kit board with up to
300mA. When the Renesas Starter Kit is connected to another system then that system should supply power to the Renesas Starter Kit.
All Renesas Starter Kit boards have an optional centre positive supply connector using a 2.1mm barrel power jack.
Warning
The Renesas Starter Kit is neither under nor over voltage protected. Use a centre positive supply for this board.
3.2. Power – Up Behaviour
When the Renesas Starter Kit is purchased the Renesas Starter Kit 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.
