Programming the kit
The kit can be programmed either from an external programming tool or through a USB bootloader which is pre-
programmed on the device.
programmed on the device.
The bootloader is evoked by pushing the push button (SW0) during power-on. I.e. push button and then connect an
USB cable to the kit. Programming can be performed through the DFU target (bootloader programmer target) with FLIP.

Connectors
The Atmel UC3-A3 Xplained kit has five 10-pin, 100mil headers. Two headers have a fixed communication interface (J1
and J4). One header has analog functionality (J2), and the last header (J3) has general purpose digital I/O.
and J4). One header has analog functionality (J2), and the last header (J3) has general purpose digital I/O.
The 90° angled header is the JTAG programming and debugging header for the AT32UC3A3256.
For the location of the respective headers, refer to

3.1
Programming header
The AT32UC3A3256 can be programmed and debugged by connecting an external programming/debugging tool to the
JTAG header. The header has a standard JTAG programmer pinout (refer to online help in Atmel Studio), and tools
such as JTAGICE3 or AVR ONE! can thus be connected directly to the header.

Note:
The grey female 10-pin header on JTAGICE mkII has to be used when connecting to the kit. A scoring in the board
is made to fit the orientation tab on the header.

Note:
A standoff adapter (no. 1) is needed when using AVR ONE!.
Note:
Pin 1 on the JTAG header is at the top right corner and is marked with a square pad.

I/O expansion headers
There are four available I/O expansion headers on the kit. Some pins have shared functionality with onboard
functionality. If “clean” expansion ports are needed, there are available cut-straps on some of the ADC inputs to remove
onboard functionality.
