Data Sheet

Introduction

The ATtiny4/5/9/10 is a low power, CMOS 8-bit microcontrollers based on the AVR

enhanced RISC archi-

tecture. The ATtiny4/5/9/10 is a 6/8-pins device ranging from 512 Bytes to 1024 Bytes Flash, with 32 Bytes

SRAM. By executing instructions in a single clock cycle, the devices achieve CPU throughput approaching

one million instructions per second (MIPS) per megahertz, allowing the system designer to optimize power

consumption versus processing speed.
