ATMEGA48P-20PU

The ATmega48P/V/88P/V/168P/V is a low power, CMOS 8-bit microcontrollers based on the AVR enhanced RISC architecture. By executing instructions in a single clock cycle, the devices achieve CPU throughput approaching one million instructions per second (MIPS) per megahertz, allowing the system designer to optimize power consumption versus processing speed.
