ATmega16/32/64/M1/C1
Table 1-1.
Note:
The ATmega16/32/64/M1/C1 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
ATmega16/32/64/M1/C1 achieves throughputs approaching 1 MIPS per MHz allowing the sys-
tem designer to optimize power consumption versus processing speed.
