2.1 Features
The following is a list of the main components and interfaces on the Atmel
AT32UC3L-EK:
• Main MCU: 32-bit Atmel AVR UC3 AT32UC3L064 (TQFP48)
o 64KBytes internal flash, 16KBytes internal RAM
o Up to 50MHz operation
o Very low power consumption
o Capacitive touch module for support of QTouch and QMatrix capture
from capacitive touch sensors
o Peripheral event system
o FlashVault allows pre-programmed, secure library support for end
user applications
• One touch rotor and five touch sensors
• One 3-axis accelerometer (connected to channels 6, 7, and 8 of the ADCIFB
module)
• One serial data flash, 64Mbits
• One RTC 32kHz crystal
• Four LEDs
• One pushbutton
• One reset pushbutton
• Wireless expansion connector for the Atmel RZ600 AT86RF231 radio board
PCBA or for any SPI-based, TWI-based, or USART-based external
communication
• 36-pin raw expansion header for GPIO access
• JTAG connector for programming and debugging on the AT32UC3L064 MCU
• Powered through the USB connector, through an external power supply (header
J2), or through a 1.2V battery (header J3)
• USB (2.0 mini A-B receptacle) connected to the 32-bit Atmel AVR UC3
AT32UC3B1256
o AT32UC3L064 and AT32UC3B1256 are connected through two pins
o one of the pre-loaded firmware on the AT32UC3B1256 acts as a
UART-USB CDC virtual com port gateway
o one of the pre-loaded firmware on the AT32UC3B1256 acts as
UART-to-USB HID QTouch Debug interface to AVR QTouch Studio
o USB mode pushbutton: with the default pre-loaded firmware on the
AT32UC3B1256, the USB mode button is used to select between the
UART-USB CDC virtual com port gateway firmware (press the USB
mode upon power up of the board) and the UART-to-USB HID
QTouch Debug interface to AVR QTouch Studio
o the J12 jumper can be used to set the AT32UC3B1256 in boot loader
mode at power up
o JTAG connector for programming and debugging the
AT32UC3B1256 (J13)
