The ATMEGA8 is 8-bit AVR Microcontroller.

The low-power Atmel 8-bit AVR RISC-based microcontroller combines 8KB of programmable flash memory, 1KB of SRAM, 512B EEPROM, and a 6 or 8 channel 10-bit A/D converter. The device supports throughput of 16 MIPS at 16 MHz and operates between 2.7-5.5 volts.

An 8-bit AVR microcontroller is a type of microcontroller developed by Atmel Corporation, which is now part of Microchip Technology Inc. It is based on an 8-bit RISC (Reduced Instruction Set Computing) architecture.
