描述 Description

Mature product; not recommended for new designs. Replaced by ATmega64A.ATmega64 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 ATmega64 achieves throughputs approaching one MIPS per MHz, allowing the system designer to optimize power consumption versus processing speed.
