ATTINY20-XUR

MCU 8Bit ATtiny AVR RISC 2KB Flash 2.5V/3.3V/5V 14Pin TSSOP T/R

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.
