Introduction
®
The Atmel
AT32UC3L-EK is an evaluation kit and development system for
®
the Atmel AVR
UC3 AT32UC3L064 microcontroller.
®
As an evaluation kit, the board focus is towards Atmel QTouch
and
™
®
QMatrix
support, and Atmel picoPower
technology.
As a development system, the board notably provides on-board memory, a
USB communication interface, an accelerometer, and the JTAG
programming and debugging interface. The AT32UC3L-EK also features
expansion headers; one of these is the wireless expansion header (named
WLESS on the PCB), which is the receptacle for one of the two RZ600 radio
boards provided in the kit package.
