ATMEGA8A – AU Microcontroller – (SMD TQFP Package) – 8-Bit 32 Pin AVR Microcontroller

The ATMEGA8A is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By executing powerful instructions in a single clock cycle, the ATMEGA8A achieves through puts approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption versus processing speed.
