ATMEL ATMEGA128A-AUR 微控制器, 8位, 低功率高性能, ATmega, 16 MHz, 128 KB, 4 KB, 64 引脚, TQFP
Overview
The ATmega128A 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 approaching 1 MIPS per MHz allowing the system designer to optimize
power consumption versus processing speed.
The AVR core combines a rich instruction set with 32 general purpose working registers. All the
32 registers are directly connected to the Arithmetic Logic Unit ALU, allowing two independent
registers to be accessed in one single instruction executedin one clock cycle. The resulting
architecture is more code efficient while achieving throughputs up to ten times faster than con
ventional CISC microcontrollers.
