ATMEGA162-16AU Datasheet

8-bit AVR Microcontroller with 16K Bytes In-System Programmable Flash


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.
