ATMEGA16A AU TQFP 44 Pin Microcontroller SMD Package

ATMEGA16A AU TQFP 44 Pin Microcontroller SMD Package 

The ATmega16A-AU is a high-performance 8-bit AVR microcontroller manufactured by Atmel (now Microchip Technology). It is a widely used member of the ATmega family, designed for embedded control, industrial automation, and educational projects.

The microcontroller is based on Harvard architecture with a RISC instruction set, enabling most instructions to execute in a single clock cycle. It integrates 16 KB of Flash memory, SRAM, EEPROM, digital I/O ports, timers, ADC, and serial communication interfaces on a single chip.

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