MICROCHIP ATmega48A ATMEGA48PA ATMEGA88A ATMEGA88PA ATMEGA168A ATMEGA168PA ATMEGA328 ATMEG328AP CMOS microcontrollers IC --ATMEGA328-MU

Introduction:

The ATmega48A/PA/88A/PA/168A/PA/328/P 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.
