The ATTINY826-XU from Microchip is an 8-bit AVR MCU operating at up to 20MHz. It provides 8KB Flash and 1KB SRAM in a 20-SSOP package. Supporting 1.8V to 5.5V, it includes PWM, WDT, and brown-out reset, making it versatile for cost-sensitive embedded designs.

  • Wide voltage range (1.8-5.5V): Works with both 3.3V and 5V logic.
  • 20MHz AVR core: Fast execution for real-time tasks.
  • 20-pin SSOP: Compact footprint for space-limited PCBs.
  • Integrated safety features: WDT and BOD enhance reliability.

Consumer Electronics

5.5V tolerance simplifies interfacing with legacy 5V sensors.

Wearable Devices

Low 1.8V operation and small SSOP package fit compact wearables.

Smart Lighting

PWM channels drive RGB LEDs with smooth color transitions.

Battery Management

WDT and brown-out reset protect battery state monitoring.

Automotive Accessories

Wide voltage range handles vehicle power fluctuations.

Educational Kits

8KB Flash is ideal for teaching embedded programming.
