ATMEGA32-16AI

Product Summary

The ATMEGA32-16AI 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 ATMEGA32-16AI achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
