The ATXMEGA64A3U is a versatile AVR MCU from Microchip, running at 32MHz with 64KB flash. It operates from 1.6V to 3.6V and includes DMA for efficient data movement. The 64-TQFP package balances I/O and size for advanced embedded applications.
- DMA controller: Reduces CPU load for high-throughput data transfers.
- Wide voltage range (1.6V): Works with modern low-voltage logic.
- 32MHz performance: Fast enough for real-time control loops.
- 64-TQFP: Good pin count for peripheral-rich designs.
High-Performance Motor Control
DMA offloads CPU for PWM updates, enabling smooth FOC on brushless motors.
Audio Effects Processors
32MHz and DMA handle real-time DSP for guitar pedals and mixers.
Industrial Automation
1.6V core with 3.6V I/O tolerance (check datasheet) interfaces with mixed-voltage systems.
Smart Grid Meters
DMA and 4KB RAM buffer metrology data for accurate billing.
Robotics
Multiple timers and PWM channels coordinate joint servos and sensors.
Portable Gaming Devices
Low power and 64KB flash support simple games and LCD drivers.
