2. Power Supply
2.1 Requirements
This RSK is supplied with an E1 debugger. The debugger is able to power the RSK board with up to 200mA. When
the RSK is connected to another system then that system should supply power to the RSK. All RSK and RSK+
boards have an optional centre positive supply connector using a 2.0mm barrel power jack.
Details of the external power supply requirements for the RSK, and connections are shown in Table 2-1 below.
Connector Supply Voltages
PWR Regulated, 5V DC

2.2 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 any switch, the LEDs will flash at a rate controlled by the potentiometer.
The main power supply connected to PWR1 should supply a minimum of 5W to ensure full functionality.
