The Microchip ATTINY806-MN is a low-power 8-bit AVR MCU with 8KB flash and 512B SRAM. Running at 20MHz with a 1.8V-5.5V supply, it offers PWM, WDT, and brown-out detection in a 20-VFQFN package. Designed for -40°C to 105°C, it is perfect for cost-sensitive embedded control in consumer and industrial applications.

  • Ultra-Low Power: AVR architecture with multiple sleep modes reduces current to microamps for battery devices.
  • Compact Footprint: 20-VFQFN (3x3mm) saves PCB space in miniaturized designs.
  • High Integration: Internal oscillator and reset circuitry minimize external components.
  • Wide Temperature: -40°C to 105°C supports automotive and industrial environments.
