ATMEGA8A AU 8 Bit 32 Pin AVR Microcontroller SMD TQFP Package

ATMEGA8A AU 8 Bit 32 Pin AVR Microcontroller SMD TQFP Package 

The ATmega8A-AU is an 8-bit AVR microcontroller from Atmel (now Microchip Technology). It belongs to the ATmega family, known for high performance, low power consumption, and versatile peripheral support.

Based on Harvard architecture with a RISC instruction set, the ATmega8A executes most instructions in a single clock cycle, providing efficient processing. The device integrates Flash program memory, SRAM, EEPROM, digital I/O, timers, ADC, and serial communication interfaces on a single chip.

The AU suffix indicates the 32-pin TQFP surface-mount package, making it suitable for compact PCB designs and modern electronic products.
