The Microchip ATTINY261A-SUR is a low-power 8-bit AVR microcontroller. It offers 2KB of Flash and 128 bytes of SRAM, running at up to 20MHz. The device operates from 1.8V to 5.5V and includes a temperature sensor, making it suitable for compact, power-sensitive applications. The 20-SOIC package is suitable for surface-mount assembly.

  • Ultra-low power consumption extends battery life.
  • Integrated temperature sensor saves board space.
  • Wide voltage range supports various power sources.
  • Small 20-SOIC package for space-constrained designs.

Battery-Powered Devices

With a 1.8V minimum supply and low-power sleep modes, it is ideal for portable sensors and remote controls.

Temperature Monitoring

The built-in temperature sensor allows for direct temperature measurement without external components.

Motor Control

PWM channels can drive small DC motors or fans in consumer electronics.

Lighting Systems

Its small footprint and PWM capability suit LED dimming and color mixing applications.

Automotive Accessories

Operating up to 85°C, it can be used in interior lighting or seat control modules.

Smart Sensors

The 2KB Flash and 128B RAM are sufficient for simple data logging and threshold detection.
