ATMEGA32C1-15MZ

8-bit Microcontroller with 16K/32K/64K Bytes In-System Programmable Flash

Atmel Corporation 

2. Overview

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.

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 independent

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 con-

ventional CISC microcontrollers.
