The ATATMEL-ICE-PCBA is a low cost version of powerful development tool for debugging and programming ARM Cortex-M based SAM and AVR microcontrollers with onchip debug capability without plastic encapsulation. It supports programming and onchip debugging of all AVR 32bit microcontrollers on both JTAG and aWire interfaces, AVR XMEGA family devices on both JTAG and PDI two wire interfaces, JTAG and SPI programming and debugging of all AVR 8bit microcontroller with OCD support on either JTAG or debugWIRE interfaces, all SAM ARM Cortex-M based microcontrollers on both SWD and JTAG interfaces and all tinyAVR 8bit microcontrollers with support for the TPI interface.
