The ATXMEGA256D3-ANR from Microchip is a 32MHz AVR microcontroller in a 64-TQFP package, supplied in tape-and-reel. It features 256KB flash and 16KB SRAM, operating at 1.6V-3.6V. With integrated PWM, POR, BOD, and WDT, it provides a robust foundation for embedded control systems.

  • Production Ready: Tape-and-reel format for efficient SMT assembly.
  • Low Power: 1.6V operation reduces energy consumption.
  • High Reliability: BOD and WDT enhance system stability.
  • Ample Storage: 256KB flash for large applications.
  • Compact Design: 64-TQFP fits space-constrained boards.

LED Lighting Control

PWM channels drive RGB LEDs with smooth dimming at 32MHz.

Battery Management

Low voltage operation and BOD protect lithium-ion cells.

Simple Robotics
