ATmega16M1/32M1/64M1 [DATASHEET]
8209ES–AVR–11/2012
Note: 1. Only for Atmel Atmega32M1/64M1.
2. On the engineering samples, the ACMPN3 alternate function is not located on PC4. It is located on PE2.
2. Overview
The Atmel ATmega16M1/32M1/64M1 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 ATmega16M1/32M1/64M1
achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption
versus processing speed.
