The Microchip ATTINY84-15MZ is an 8-bit AVR microcontroller offering 8KB of flash and 512 bytes of SRAM in a compact 20-WFQFN package. It operates at up to 16MHz and supports a voltage range of 2.7V to 5.5V. With integrated PWM, WDT, and brown-out detection, it is designed for low-power and space-constrained applications.

  • Ultra-Compact Package: 20-WFQFN with exposed pad for thermal management.
  • Low Power Consumption: Suitable for battery-operated devices.
  • High-Speed AVR Core: 16MHz performance for time-critical tasks.
  • Robust Protection: Includes brown-out detect and WDT for system reliability.

Sensor Nodes

The 8KB flash and 512 bytes RAM are sufficient for reading and transmitting data from temperature or humidity sensors in IoT nodes.

Motor Control

With PWM and a 16MHz clock, it can drive small DC motors in toys or drones with precise speed control.

Portable Instruments

Low power consumption and 2.7V operation enable battery-powered multimeters and handheld testers.

LED Matrix Displays

Use the GPIO and PWM to drive small LED matrices for signage or status indicators.

Security Systems

The WDT and brown-out reset ensure reliable operation in alarm panels and access control units.

Wearable Devices

The compact 20-WFQFN package and low power make it suitable for fitness bands and smart watches.
