Description
The UC3-A3 Xplained evaluation kit is a hardware platform for evaluating the AT32UC3A3256 microcontroller. However the makers of the kit boast off about the 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 kit offers a range of features that enable the 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.
The AES peripheral of the UC3A3S/A4S and the Audio peripheral of the UC3A3AU are not supported by the device on this board.
Features
- Atmel AT32UC3A3256 microcontroller
