ATMEGA64A - AU Microcontroller - (SMD TQFP Package) - 8-Bit 64 Pin 64KB Flash Microcontroller

The ATMEGA64A 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 ATMEGA64A achieves through puts close to 1MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed.
