ATMEGA128A-AU

8位微控制器 -MCU 128K Flash 4K EEPROM 4K SRAM 53 IO Pins 8-bit AVR Microcontroller


Introduction ATMEGA128A-AU

The Atmel®  ATMEGA128A-AU 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 ATmega128A achieves throughputs close to 1MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed.
