Features

The following is a list of the main components and interfaces on the AT32UC3L-EK:

• Main MCU: Atmel AVR UC3 32-bit AT32UC3L064 (TQFP48)

  • 64KB internal flash, 16KB internal RAM

  • Up to 50MHz operation

  • Very low power consumption

  • Capacitive touch module for support of QTouch and QMatrix capture from capacitive touch sensors

  • Peripheral event system

  • 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, 64Mb

• One RTC 32kHz crystal

• Four LEDs

• One pushbutton

• One reset pushbutton

• Wireless expansion connector for the RZ600 AT86RF231 radio board PCBA or for y 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), or through a 1.2V battery (header J3)

• USB (2.0 Mini-AB receptacle) connected to the 32-bit AVR UC3 AT32UC3B1256

  • AT32UC3L064 and AT32UC3B1256 are connected through two pins

  • One of the pre-loaded firmware on the AT32UC3B1256 acts as a UART-USB CDC virtual com port gateway

  • One of the pre-loaded firmware on the AT32UC3B1256 acts as UART-to-USB HID QTouch Debug interface to AVR QTouch Studio

  • 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

  • The J12 jumper can be used to set the AT32UC3B1256 in boot loader mode at power up

  • JTAG connector for programming and debugging the AT32UC3B1256 (J13)
