The Microchip ATTINY816-SN is a low-power 8-bit AVR microcontroller in a 20-pin SOIC package. It features 8KB Flash and 512 bytes of SRAM, running at up to 20MHz. With a supply range of 1.8V to 5.5V, it includes PWM, WDT, and Brown-out detection. This MCU is optimized for extended-temperature applications requiring compact, reliable control.

  • Extended temperature range: -40°C to 105°C suits harsh automotive and industrial settings.
  • Low power consumption: Ideal for battery-operated devices with sleep modes.
  • 8KB Flash: Ample space for mid-complexity firmware without external memory.
  • 20-pin SOIC: Easy to handle and solder, suitable for prototyping and mass production.
  • Integrated safety peripherals: WDT and BOR improve system reliability.

Automotive Interior Lighting

The 105°C maximum temperature rating allows placement near hot engine bays or dashboards. PWM outputs drive RGB LEDs for ambient lighting with smooth color transitions.

Industrial Process Control

With 8KB Flash and 512B RAM, it can handle PID loops for temperature or pressure control. The WDT ensures recovery from software hangs in continuous operation.

Smart Agriculture Sensors

Low-power sleep modes and a 1.8V minimum supply make it ideal for soil moisture sensors powered by solar cells. The wide SOIC package is easy to solder in rugged PCBs.

Consumer Appliances

This MCU can manage user interfaces (buttons, LEDs) and motor timing in blenders or fans. The 20-pin SOIC provides enough I/O for multiple inputs and outputs.

IoT End Nodes

Its low power consumption and integrated WDT make it a reliable controller for periodic data acquisition and transmission in wireless sensor networks.

Power Tool Safety Controllers

The extended temperature range and robust reset features support operation in high-vibration, high-temperature power tool environments.
