ATTINY45V-10SI

MCU 8Bit ATtiny AVR RISC 4KB Flash 2.5V/3.3V/5V 8Pin SOIC EIAJ

Overview

The ATtiny25/45/85 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 ATtiny25/45/85 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
