The Microchip ATTINY427-MF is a low-power 8-bit AVR microcontroller in a compact 24-VFQFN package. It delivers 4KB flash and 512 bytes RAM, running at up to 20MHz. With a 1.8V to 5.5V supply range and integrated brown-out detection, POR, PWM, and WDT, it is engineered for reliable operation in space-constrained, battery-powered applications.

  • Ultra-low power consumption: 1.8V operation extends battery life in portable designs.
  • Wide voltage range (1.8V-5.5V): simplifies power supply design and supports 5V legacy systems.
  • High-temperature tolerance (-40°C to 125°C): ensures reliability in industrial and automotive environments.
  • Compact 24-VFQFN package: saves PCB space while providing exposed pad for thermal dissipation.

Battery-Powered Sensor Nodes

The 1.8V minimum supply and low-power sleep modes enable long battery life in IoT and remote monitoring devices.

Motor Control for Small Appliances

With PWM outputs and a 20MHz AVR core, it can generate precise control signals for brushless DC motors in fans or pumps.

LED Lighting Controllers

Multiple PWM channels allow smooth dimming and color mixing in RGB LED strips, with the 5.5V max supply supporting direct LED drive.

Industrial Automation I/O Modules

The -40°C to 125°C temperature range and robust peripherals (WDT, BOD) make it reliable for harsh factory floor environments.

Portable Medical Devices

Low power consumption and small 24-VFQFN package fit wearable health monitors that require continuous sensing.

Automotive Interior Lighting

Wide voltage tolerance and high-temperature rating support interior ambient lighting control in vehicles.
