The Microchip ATtiny1606 is an 8-bit AVR MCU with 16KB flash and 1KB RAM. It operates from 2.7V to 5.5V at up to 16MHz. Integrated BOD, POR, PWM, and WDT enhance system reliability. The 20-VFQFN package supports high-temperature automotive and industrial applications.

  • High-temperature tolerance (125°C) – suitable for harsh environments.
  • Wide voltage range (2.7-5.5V) – flexible power supply design.
  • 16MHz AVR core – efficient for 8-bit applications.
  • Compact 20-VFQFN – reduces board footprint.

Automotive Body Electronics

125°C rating and 5.5V operation suit engine bay sensors.

LED Lighting Control

PWM outputs drive dimming circuits with high resolution.

Power Tools
