ATMEGA64A AU 8 Bit 64 Pin 64KB Flash Microcontroller SMD TQFP Package

ATMEGA64A AU 8 Bit 64 Pin 64KB Flash Microcontroller SMD TQFP Package

The ATmega64A-AU is a high-performance 8-bit AVR microcontroller manufactured by Atmel (now Microchip Technology). It belongs to the ATmega family and is designed for complex embedded and industrial applications requiring large program memory and extensive I/O capability.

The microcontroller is based on Harvard architecture with a RISC instruction set, enabling most instructions to execute in a single clock cycle. It integrates 64 KB of Flash program memory, SRAM, EEPROM, multiple timers, ADC, and communication interfaces on a single chip.

The AU suffix denotes the 64-pin TQFP surface-mount package, making it suitable for high-pin-count, compact PCB designs.
