8-bit AVR Microcontroller
ATmega16M1/32M1/64M1
DATASHEET SUMMARY
Introduction
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 close to 1 MIPS per MHz.
This empowers system designer to optimize the device for power
consumption versus processing speed.
