The STM8S001J3M3 from STMicroelectronics is an 8-bit STM8 microcontroller in an 8-pin SOIC package. It operates from 2.95V to 5.5V and runs at 16MHz, with 8KB Flash and 1KB RAM. It includes a 10-bit ADC, PWM, brown-out reset, and watchdog timer, designed for robust performance in industrial and automotive applications.

  • Wide Voltage Range: 2.95V to 5.5V supports both 3.3V and 5V logic systems.
  • Extended Temperature: -40°C to 125°C ensures reliability in harsh environments.
  • 8KB Flash: Ample code space for complex control algorithms.
  • Robust I/O: High sink/source current for direct LED and relay driving.
  • Mature STM8 Core: Proven architecture with extensive peripheral set.

Industrial Sensor Interfaces

The wide temperature range (-40°C to 125°C) and 5V tolerance make it ideal for factory automation sensors.

Automotive Body Electronics

With 8KB Flash and robust I/O, it handles window lift or mirror control modules in vehicles.

Power Supply Monitoring

Its 16MHz core and ADC can monitor voltage/current in SMPS units with fast response.

HVAC Control Boards

5V operation simplifies direct interfacing with relays and triacs in heating/cooling systems.

Consumer Appliances

Use it for washing machine timers or microwave control panels with PWM for motor speed.

Lighting Ballasts

High-temperature rating supports LED drivers in enclosed fixtures where heat dissipation is limited.
