ATMEGA2560 16AU TQFP 100 Pin Microcontroller SMD Package

ATMEGA2560 16AU TQFP 100 Pin Microcontroller SMD Package 

The ATmega2560-16AU is a high-performance 8-bit AVR microcontroller developed by Atmel (now Microchip Technology). It is a powerful member of the ATmega family and is widely known as the main controller used in the Arduino Mega 2560 board.

The microcontroller is based on Harvard architecture with a RISC instruction set, allowing most instructions to execute in a single clock cycle. It integrates large program memory (256 KB Flash), extensive I/O capability, multiple timers, ADC, and several communication interfaces, making it suitable for complex and large embedded systems.

The 16AU variant operates at 16 MHz and comes in a 100-pin TQFP SMD package, ideal for high-pin-count and advanced PCB designs.
