ATmega48/V/88/V/168/V - Microchip Technology

ATmega48/V/88/V/168/V Introduction The ATmega48/V/88/V/168/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
