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. This board
has an optional centre positive supply connector using a 2.0mm barrel power jack.
Details of the external power supply requirements for the RSK, and configuration are shown in
Table 2-2
below. The default RSK power configuration is shown in bold, blue text.

2.2 Power-Up Behaviour
When the RSK is purchased, the RSK board has the 'Release' build of the example tutorial software pre-
programmed into the Renesas microcontroller. Please consult the 'Renesas Starter Kit Code Generator
Tutorial Manual' for further information of this example.
The main power supply connected to PWR should supply a minimum of 5W to ensure full functionality.
