2. Overview
7647A–AVR–02/08
Table 1-1.
Note:
The ATmega32/64/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
ATmega32/64/M1/C1 achieves throughputs approaching 1 MIPS per MHz allowing the system
designer to optimize power consumption versus processing speed.
