32-bit AVR UC3 Flash Microcontrollers feature:

- True 1.6V operation

- More MHz per mW

- Unrivalled DSP performance

- Peripheral DMA controller

HIGHER CPU PERFORMANCE

- The 32-bit AVR CPU and its tightly

coupled dual port SRAM allow fast

computation without latencies from

pipeline stalls or system bus

arbitrations.

DETERMINISTIC REAL-TIME CONTROL

- Fast context switches, atomic peripheral

read- modify-write access and a fully

autonomous Peripheral Event System

allow predictable external event handling.

HIGH RELIABILITY

- The 32-bit AVR UC3 microcontrollers boot safely from

the on-board RC oscillator, and return to RC oscillator

operation if external crystal oscillator failure is detected.

The brown-out detector and the windowed hardware

watchdog protect the system from environmental malfunctions.

The non-maskable interrupt ensures critical event

handling. The MPU and privileged operating modes keep the

kernel safe from runaway application code.
