The Microchip ATTINY1634-MN is a low-power 8-bit AVR microcontroller in a 20-WFQFN package. It features 16KB of Flash and 1KB of RAM, operating at speeds up to 12 MHz. With a wide voltage range starting at 1.8V, it is optimized for battery-powered and portable applications.

  • Ultra-Low Power: Designed for battery-powered applications with a 1.8V minimum supply and multiple sleep modes.
  • Compact Size: The 20-WFQFN package is one of the smallest options for 16KB of memory.
  • High Temperature Tolerance: Rated up to 105°C, suitable for demanding environments.
  • Simple Architecture: The AVR core is easy to program and debug, reducing development time.

Battery-Powered IoT Sensors

Its low voltage operation (1.8V) and power-saving modes make it perfect for battery-powered wireless sensor nodes.

LED Lighting Control

Use the PWM channels to create dynamic lighting effects and color mixing in RGB LED strips and fixtures.

Small Motor Drivers

Control the speed and direction of small DC motors in toys, drones, and mini-pumps.

Capacitive Touch Buttons

Implement simple touch-sensitive buttons using the integrated analog comparators and timers.

System Management (BMC)

Monitor system voltages, temperatures, and fan speeds in a computer or server, providing control and alerting.

Portable Health Monitors

Process signals from simple health sensors like heart rate or temperature monitors in wearable devices.
