The ATTINY85-15MT1 is a low-power 8-bit AVR microcontroller with 8KB flash and 512 bytes SRAM. It runs at 16MHz and supports 2.7V to 5.5V supply. The 20-WFQFN package is ideal for compact designs requiring PWM and analog sensing.

  • Ultra-compact: 20-WFQFN package minimizes board space.
  • Low power: Suitable for battery-operated applications.
  • Wide voltage range: 2.7V to 5.5V simplifies power supply design.
  • Integrated peripherals: PWM and ADC reduce external components.

LED Lighting

PWM outputs allow smooth dimming and color mixing in compact lighting modules.

Battery-Powered Devices

Low power consumption and wide voltage range support direct battery operation.

Sensor Interfaces

10-bit ADC reads analog sensors for temperature, light, or pressure monitoring.

Small Appliances

8KB flash is sufficient for simple control loops in blenders, fans, and heaters.

Wearable Electronics

Small WFQFN package fits into tight form factors for fitness trackers.

Automotive Accessories

105°C rating allows use in cabin electronics like window controls.
