The ATTINY1626-SUR is an 8-bit AVR microcontroller from Microchip. It operates from 1.8V to 5.5V and runs at 20MHz. With 16KB flash and 2KB RAM, it offers ample resources for mid-complexity tasks. The 20-SOIC package is easy to solder. Integrated features include brown-out reset, POR, PWM, and WDT.

  • Large flash (16KB) – more code space.
  • 2KB RAM – supports data buffers.
  • Wide voltage – flexible power.
  • AVR core – well-documented ecosystem.

Wearable Devices

Low voltage (1.8V) and small SOIC-20 package fit wristbands.

Sensor Nodes

16KB flash allows complex sensor fusion algorithms.

LED Matrix Displays

PWM channels drive RGB LEDs; 2KB RAM buffers frames.

Smart Locks

Brown-out reset protects key storage; WDT prevents lockups.

Drone Controllers

20MHz speed handles ESC signals; 5.5V tolerance for battery monitoring.

Industrial Sensors

Wide temperature range (-40°C to 85°C) suits factory floors.
