Connectors
The UC3-L0 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.
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 AT32UC3L064.
For the location of the respective headers, refer to

3.1
Programming Headers
The Atmel AT32UC3L064 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 AVR Studio), and
tools such as JTAGICE mkII or AVR ONE! can thus be connected directly to the header.
to the JTAG header. The header has a standard JTAG programmer pinout (refer to online help in AVR Studio), and
tools such as JTAGICE mkII 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 the AVRONE!.
Note:
Pin 1 on the JTAG header is at the top right corner. This is rotated 180° compared to the other headers (J1, J2, J3, and
J4).

The Atmel AT32UC3B1256 can be programmed through its boot loader. The boot loader is evoked by shorting the two
holes close to the device before applying power to the board. The two holes have 100mil spacing, so the user can
solder in a two-pin header and use a jumper to easily enter the boot loader. Programming is performed through the boot
loader programmer target in AVR32 Studio.

Alternatively, the AT32UC3B1256 can also be programmed by connecting a programming tool, such as JTAGICE mkII,
to the 10-pin test points on the bottom side of the board (marked with BC JTAG).

Note:
It is not recommended to program the AT32UC3B1256 using a programming tool, as this will erase the boot loader.

I/O Expansion Headers
There are four available I/O expansion headers on the kit. Because of the low pin count on the device, the I/O
expansion header pins are shared with onboard functionality. If “clean” expansion ports are needed, cut-straps are
available on some of the ADC inputs. Otherwise, it is only needed to remove a series resistor to remove onboard
functionality.
