Atmel-ICE is a powerful development tool for debugging and programming Arm Cortex-M based Microchip SAM and Microchip AVR microcontrollers with On-Chip Debug capability.
It supports:
Programming and on-chip debugging of all Microchip AVR UC3 microcontrollers on both JTAG and aWire interfaces
Programming and on-chip debugging of all AVR XMEGA family devices on both JTAG and PDI two-wire interfaces
Programming (JTAG and SPI) and debugging of all AVR 8-bit microcontrollers with OCD support on both JTAG or debugWIRE interfaces
Programming and debugging of all Microchip SAM Arm Cortex-M based microcontrollers on both SWD and JTAG interfaces
Programming (TPI) of all Microchip tinyAVR 8-bit microcontrollers with support for this interface
