Atmel ATmega16/32/64/M1/C1
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
system designer to optimize power consumption versus processing speed.
Figure 2-1.
The AVR core combines a rich instruction set with 32 general purpose working registers. All
the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two inde-
pendent registers to be accessed in one single instruction executed in one clock cycle. The
resulting architecture is more code efficient while achieving throughputs up to ten times faster
than conventional CISC microcontrollers.
