ATMEGA32A AU TQFP 44 Pin Microcontroller SMD Package

ATMEGA32A AU TQFP 44 Pin Microcontroller SMD Package 

The ATmega32A-AU is a high-performance 8-bit AVR microcontroller from Atmel (now Microchip Technology). It is a widely used member of the ATmega family, suitable for embedded control, industrial, and educational applications.

The microcontroller is based on Harvard architecture and a RISC instruction set, allowing most instructions to execute in a single clock cycle. It integrates 32 KB Flash memory, SRAM, EEPROM, multiple I/O ports, timers, ADC, and serial communication interfaces on a single chip.

The AU suffix denotes the 44-pin TQFP surface-mount package, which is ideal for compact PCB designs and mass-production electronics.
