ATTINY461/V

8-bit Microcontroller with 2/4/8K Bytes In-System Programmable Flash

Atmel Corporation 

ATtiny261/461/861

2. Overview

The ATtiny261/461/861 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

ATtiny261/461/861 achieves throughputs approaching 1 MIPS per MHz allowing the system

designer to optimize power consumption versus processing speed.
