産品概述

8Bit AVR Microcontroller with 128K Bytes In-System Programmable Flash

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.
