The Atmel® UC3-A3 Xplained evaluation kit is a hardware platform for evaluating the Atmel AT32UC3A3256 microcontroller. The kit offers a range of features that enable the Atmel AVR® UC3 user to get started using AVR UC3 peripherals right away and understand how to integrate the AVR UC3 device in their own design.

NOTE: The UC3-A3 Xplained is suited for evaluation of both UC3A3 and UC3A4 microcontrollers. The two series share the same peripherals, except that the UC3A3 features a External Bus Interface (EBI) while the UC3A4 does not.
The AES peripheral of the UC3A3S/A4S and the Audio peripheral of the UC3A3AU are not supported by the device on this board. To evaluate these features please use the EVK1104S and EVK1104AU respectively.
