The Microchip ATTINY826-XFR is an 8-bit AVR MCU with a 20MHz core, housed in a 20-SSOP package. It provides 8KB flash and 1KB SRAM, operating from 1.8V to 5.5V. With a -40°C to +125°C range and integrated BOD, POR, PWM, and WDT, it is built for harsh environments.

  • Extended temperature range (-40°C to +125°C): Reliable in automotive and industrial settings.
  • 20MHz performance: Faster response for time-critical control loops.
  • 8KB flash: Ample code space for complex applications.
  • SSOP-20 package: Easy to solder and inspect, ideal for production.

Automotive Interior Lighting

125°C rating and PWM channels drive LED ambient lighting in cabins.

Industrial Valve Controllers

20MHz speed enables precise timing for proportional valve actuation.

HVAC Zone Controllers

8KB flash stores multiple control algorithms; WDT ensures fail-safe operation.

Power Tool Safety Interlocks

High-temperature tolerance and BOD protect against thermal stress in motors.

Smart Agriculture Probes

Low power consumption and wide voltage range suit soil sensor nodes.

Robotic Actuators

Fast PWM updates allow smooth servo control in collaborative robots.
