The Microchip ATTINY1626-XF is a low-power 8-bit AVR microcontroller in a compact 20-pin SSOP package. It delivers 16KB Flash and 2KB SRAM at speeds up to 20MHz, operating from 1.8V to 5.5V. Built-in features like Brown-out Detection, Power-On Reset, PWM, and Watchdog Timer simplify robust system design. Its extended temperature range supports demanding industrial and automotive applications.

  • Ultra-low power consumption: 1.8V operation extends battery life in portable designs.
  • High-temperature capability: Rated to 125°C for automotive and industrial use.
  • Compact SSOP package: Saves PCB space without sacrificing I/O count.
  • Integrated safety features: BOD, POR, and WDT improve system reliability.

Battery-Powered IoT Sensors

The 1.8V minimum supply and low-power sleep modes enable long battery life in wireless sensor nodes.

Motor Control for Small Appliances

With PWM and a 20MHz AVR core, it can generate precise control signals for brushless DC motors.

Industrial Automation I/O Modules

The wide temperature range (-40°C to 125°C) and robust BOD ensure reliable operation in harsh factory environments.

Portable Medical Devices

Low voltage operation and small SSOP footprint fit compact, power-efficient health monitors.

Automotive Body Electronics

High-temperature tolerance and WDT make it suitable for in-cabin control modules like window lifters.

Smart Home Controllers

16KB Flash provides enough code space for lighting or thermostat control algorithms with PWM dimming.
