The Microchip ATMEGA325P-20AU is an 8-bit AVR MCU with 32KB flash and 2KB RAM. Running at 20MHz from 2.7V to 5.5V, it includes PWM, brown-out detection, and WDT. The 64-TQFP package provides ample I/O for complex embedded systems.

  • High I/O count (64-pin) for peripheral-rich designs.
  • 20MHz speed for real-time tasks.
  • 32KB flash for substantial firmware.
  • Robust protection features (BOD, POR, WDT).

Industrial Displays

64-pin package and 32KB flash support graphic LCD interfaces.

Motor Control
