ATTINY13A

8-bit Microcontroller with 1K Bytes In-System Programmable Flash

Atmel Corporation 

2. Overview

The ATtiny13A 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 ATtiny13A achieves

throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power con-

sumption versus processing speed.
