The Microchip ATTINY826 is an 8-bit AVR microcontroller in a 20-pin SSOP package. It operates from 1.8V to 5.5V at speeds up to 20MHz. With 8KB flash and 1KB RAM, it includes PWM, WDT, and brown-out reset. Its -40°C to 125°C range makes it suitable for automotive and industrial applications.

  • High-temperature operation (125°C) – ideal for under-hood and industrial use.
  • 20-pin SSOP – compact yet enough I/O for complex tasks.
  • AVR core efficiency – low power consumption at 20MHz.
  • 1KB RAM – sufficient for real-time data processing.

Human-Machine Interface (HMI)

20-pin SSOP and 8KB flash support keypads and LED indicators in control panels.

Battery Management Systems

Low 1.8V operation and 1KB RAM handle cell monitoring in portable devices.

Sensor Fusion Hubs

Multiple PWM channels and 20MHz speed process accelerometer and gyro data.

Smart Lighting Controllers

High-temperature rating (125°C) suits LED drivers in enclosed fixtures.

Motor Drivers for Drones

Compact package and fast PWM enable ESC control in small UAVs.

Security Systems

WDT and brown-out reset ensure reliable operation in alarm panels.
