Atmel® ATmega48/V/ 88/V /168/V is a low power CMOS based on AVR® enhanced RISC architecture It is an 8-bit microcontroller. The ATmega48/V/88/V /168/V achieves near 1MIPS per MHz throughput by executing powerful instructions in a single clock cycle. This empowers the system designer to optimize the device for processing speed versus power consumption.
