The Microchip ATXMEGA128A4U-CU is a high-performance 8/16-bit AVR microcontroller with 128KB flash and 8KB SRAM. Operating at up to 32MHz with a 1.6V to 3.6V supply, it integrates DMA, PWM, and robust reset features. The 49-VFBGA package is suited for space-constrained designs requiring low power and high integration.
- Ultra-low voltage operation (1.6V) – extends battery life in portable devices.
- DMA controller – offloads data transfer tasks from the CPU, improving throughput.
- 32MHz AVR core – delivers fast processing for real-time control.
- Compact 49-VFBGA – saves board space without sacrificing I/O capability.
Battery-Powered IoT Sensors
The 1.6V minimum supply voltage and low-power AVR core enable long battery life in wireless sensor nodes.
Motor Control Systems
With 32MHz speed and built-in PWM, it can generate precise control signals for brushless DC motors.
Portable Medical Devices
The 8KB SRAM and DMA controller allow efficient data handling from analog front-ends in glucose meters or pulse oximeters.
Industrial Automation
Brown-out detection and watchdog timer ensure reliable operation in noisy industrial environments.
Smart Home Controllers
128KB flash memory supports complex firmware for home automation hubs, while the VFBGA package saves PCB space.
Data Logging Systems
DMA transfers data to memory without CPU intervention, ideal for high-speed logging from multiple sensors.
