The ATTINY417-MFR from Microchip is an 8-bit AVR MCU operating at 16MHz. It features 4KB flash and 256B RAM. The 24-VFQFN package is suitable for compact and high-temperature applications. Integrated brown-out reset, POR, and WDT enhance reliability. Supports 2.7V to 5.5V supply.

  • Extended temperature range: -40°C to 125°C for demanding environments.
  • High integration: Brown-out detect, POR, and WDT reduce external components.
  • Compact 24-VFQFN: Saves space in miniaturized designs.
  • AVR architecture: Efficient C-code execution and rich peripheral set.

Automotive Sensor Interfaces

125°C rating and 5.5V operation handle under-hood temperature extremes.

Industrial Lighting Control

AVR core with PWM drives LED dimming in harsh factory environments.

Portable Instrumentation
