Microchip ATMEGA8 Microcontroller – (SMD TQFP Package) – 8-Bit 32 Pin AVR Microcontroller

The ATMEGA8A is an 8-bit CMOS microcontroller with low power consumption based on the AVR RISC architecture. The ATMEGA8A delivers throughputs approaching 1 MIPS per MHz by executing strong instructions in a single clock cycle, allowing the system designer to optimize power consumption versus processing performance.
