Atmel-11253A-ATARM-SAM4C32-EK-UserGuide_17-Sep-14

1. SAM4C32-EK Specifications

The SAM4C32-EK is shipped in a protective anti-static package. The board system

must not be subjected to high electrostatic discharge.

We strongly recommend using a grounding strap or similar ESD protective device when

handling the board in hostile ESD environments (offices with synthetic carpet, for

example). Avoid touching the component pins or any other metallic element on the

board.

1.1 Battery

The SAM4C32-EK ships with a 3V coin battery. This battery is not required for the board to start up as long as

jumper JP8 is closed.

The coin battery is provided for user convenience in case the user would like to exercise the date and time backup

function of the SAM4C32 devices when the board is switched off.

1.2 Recovery Procedure

The demo software is stored in internal Flash memory. If the content of the internal Flash has been erased, it can

be reprogrammed recovered to the state as it was when shipped by Atmel using Atmel SAM-BA® In-system

Programmer available on the Atmel website (www.atmel.com). The binary file of the demo software is also

available on the Atmel website.

2. Power Up

2.1 Power Up the Board

Unpack the board taking care to avoid electrostatic discharge. Unpack the power supply, select the power plug

adapter corresponding to that of your country, and insert it in the power supply.

Connect the power supply DC connector to the board and plug the power supply to an AC power plug. The board

LCD should light up and display a graphic demo program.

2.2 Sample Code and Technical Support

After boot up, designers can run sample code or their own application on the development kit. Users can download

sample code and get technical support from the Atmel website. The SAM4C32-EK is supported by the Atmel

Software Framework (ASF) which is also available on the Atmel website.
