ATMEGA88PA-AU

IC MCU 8BIT 8KB FLASH 32TQFP

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 sys tem designer to optimize power consumption versus processing speed.
