The ATTINY85V-10MU is an 8-bit AVR microcontroller from Microchip with 8KB flash and 512 bytes RAM. It runs at 10MHz with 1.8V-5.5V supply. The 20-WFQFN package includes PWM, WDT, and brown-out detection, optimized for ultra-low-power and space-constrained designs.

  • Ultra-low power: 1.8V operation extends battery life.
  • Tiny footprint: 20-WFQFN saves PCB space.
  • Simple architecture: Easy to program with Arduino support.
  • Integrated analog: ADC and PWM reduce external parts.

Wearable Devices

Low voltage (1.8V) and small QFN package fit compact fitness trackers.

LED Wearables

PWM channels drive RGB LEDs with minimal power consumption.

Sensor Nodes

8KB flash stores calibration data and simple polling routines.

Battery Management

Brown-out detection prevents deep discharge in Li-ion packs.

Toy Controllers

Low cost and small size make it ideal for interactive toys.

Analog Interfaces

Built-in ADC with 10-bit resolution reads potentiometers and sensors.
