The ATTINY167-MU from Microchip is an 8-bit AVR MCU with 16KB flash and 512B RAM. It operates at 16MHz with 1.8V-5.5V, featuring a temperature sensor, PWM, brown-out reset, and WDT. The 32-VFQFN package is suited for compact automotive and industrial designs.

  • Integrated temperature sensor – reduces external components.
  • Wide voltage range – flexible power supply options.
  • AVR core – efficient code density.
  • Small QFN package – saves PCB space.

Automotive LIN Nodes

Integrated LIN controller and temp sensor make it ideal for car body control modules.

Battery Management Systems

Low voltage operation and ADC monitor cell voltages in battery packs.

HVAC Actuators

PWM outputs drive stepper motors in air conditioning vents.

Industrial Process Sensors

WDT and brown-out reset ensure reliable operation in harsh environments.

Consumer Appliances
