The AT32UC3B064-A2UR is a 32-bit AVR microcontroller from Atmel running at 60MHz. It offers 64KB of flash and 16K x 8 RAM, operating from 1.65V to 3.6V. In a 64-TQFP package, it includes brown-out detection, DMA, POR, PWM, and WDT for robust embedded designs.
- High-speed AVR core: Efficient 32-bit processing at 60MHz.
- Integrated brown-out detection: Prevents erratic behavior during voltage dips.
- DMA controller: Enables high-throughput data movement without CPU intervention.
- Compact 64-TQFP: Ideal for space-limited PCB layouts.
USB Peripherals
60MHz AVR core with DMA handles high-speed USB 2.0 data transfers in dongles and adapters.
IoT Sensor Nodes
Low 1.65V operation and brown-out detection enable reliable battery-powered environmental monitoring.
Motor Control
PWM channels drive BLDC motors in drones; WDT prevents firmware lockups.
Audio Processing
16K RAM buffers audio samples; DMA offloads CPU for real-time effects in portable speakers.
Industrial HMI
64KB flash stores UI graphics; TQFP package fits compact control panels.
Smart Lighting
PWM dimming and POR ensure smooth startup in LED drivers.
