ATTINY20-MMHR集成电路（IC）的微控制器规格书PDF中文资料

Overview

ATtiny20 is a low-power CMOS 8-bit microcontroller based on the compact AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny20 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
