ATmega8A-PU Microcontroller – 8-bit AVR, DIP-28 Package

The ATmega8A-PU is a low-power, high-performance 8-bit AVR microcontroller based on the RISC architecture. With 8KB of Flash memory, 1KB of SRAM, and 512 bytes of EEPROM, this microcontroller is well-suited for embedded systems, DIY electronics, robotics, automation, and industrial control applications.

Housed in a standard DIP-28 package, the ATmega8A-PU is ideal for breadboard prototyping and through-hole PCB designs. It features rich peripherals including timers, ADC, USART, SPI, I2C, and supports in-system programming (ISP) via SPI.
