The Microchip ATMEGA32M1-AU is an 8-bit AVR microcontroller with 32KB flash and 2KB SRAM, operating at up to 16MHz. It supports 2.7V to 5.5V supply and includes a temperature sensor, PWM, and brown-out detection. Packaged in a 32-TQFP, it is designed for motor control and automotive applications requiring high integration.
- Motor control optimized: Dedicated PWM and ADC peripherals reduce external circuitry for BLDC drives.
- Wide voltage range: 2.7V-5.5V allows operation from Li-ion batteries or regulated 5V rails.
- Integrated temperature sensor: Enables thermal shutdown without external thermistors.
- Compact 32-TQFP: Saves board space while providing enough I/O for control loops.
