The Microchip ATTINY13A-SSUR is a compact AVR microcontroller in an 8-pin SOIC package. It operates from 1.8V to 5.5V and runs at up to 20MHz. With 1KB Flash and 64 bytes SRAM, it includes PWM, brown-out detection, POR, and WDT. This tiny MCU is perfect for cost-sensitive, space-constrained applications.

  • Ultra-small 8-SOIC package – fits in tight spaces.
  • Wide voltage range (1.8V-5.5V) – flexible power options.
  • 20MHz speed – fast for its size.
  • Integrated PWM – reduces external components.

Small Appliance Controls

1KB Flash is sufficient for simple timer and switch logic in coffee makers or fans.

LED Blinkers and Indicators

PWM output drives LED patterns with minimal code.

Battery-Powered Toys

Low voltage operation and small size fit toy controllers.

Sensor Interfaces

Reads analog sensors and outputs digital signals in compact designs.

Power Supply Sequencing

POR and WDT ensure proper startup/shutdown in power boards.

Hobbyist Projects

Simple architecture and 8-pin package make it easy for prototyping.
