Datasheet

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.
