2. Overview
8209D–AVR–11/10
Table 1-1.
Note:
The 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.
