Product Summary

The ATMEGA645-16MU 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 ATMEGA645-16MU achieves throughputs pproaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The ATMEGA645-16MU is manufactured using Atmel high density non-volatile memory technology.
