ATMEGA64A-MU

8位微控制器 -MCU 64K Flsh 2K EEPROM 4K SRAM 16MHz

Introduction ATMEGA64A-MU

The Atmel® ATMEGA64A-MU 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 throughputs close to 1MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed.
