ATmega 系列 16 MHz 32 KB 闪存 2 KB SRAM 8 位 微控制器 - MLF-44
Overview
The ATmega32 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 ATmega32 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power con sumption versus processing speed.
