The Microchip ATXMEGA32E5-M4NR is a high-performance 8/16-bit AVR microcontroller with 32KB flash and 4KB SRAM. It operates at up to 32MHz with a supply voltage from 1.6V to 3.6V. This device integrates DMA, PWM, brown-out detection, and a watchdog timer, making it ideal for real-time embedded control in a compact 32-UFQFN package.

  • Ultra-low power operation: 1.6V minimum supply extends battery life in portable devices.
  • High-speed AVR core: 32MHz execution for time-critical control loops.
  • Integrated DMA: Reduces CPU load during data transfers, improving system efficiency.
  • Compact package: 32-UFQFN saves PCB space for space-constrained designs.
  • Robust protection: POR, BOD, and WDT enhance system reliability in harsh environments.

Battery-Powered IoT Sensors

The 1.6V minimum supply and low-power sleep modes enable long-lasting operation in wireless sensor nodes.

Motor Control for Drones

With 32MHz speed and PWM channels, it can generate precise control signals for brushless DC motors.

Portable Medical Devices
