ATMEGA64-8AU

Product Summary

The ATMEGA64-8AU 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 device achieves throughputs approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption versus processing speed. The ATMEGA64-8AU is manufactured using Atmel’s high-density non-volatile memory technology.
