ATMEGA162-16PI

MCU 8Bit ATmega AVR RISC 16KB Flash 3.3V/5V 40Pin PDIP W

Overview

The ATmega162 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega162 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
