The STM8S903F3M3TR is a tape-and-reel version of the STM8S903F3M3 microcontroller from STMicroelectronics. It features the same 8-bit STM8 core at 16 MHz, 8 KB of flash, and 1 KB of RAM in a 20-SOIC package. Operating from 2.95V to 5.5V, it includes brown-out detection and a watchdog timer for dependable operation. This variant is specifically packaged for automated pick-and-place manufacturing, reducing assembly costs for high-volume projects.
- Tape-and-Reel Packaging: Streamlines SMT assembly, reducing production time and cost.
- Proven STM8 Core: Offers a mature, stable architecture with extensive development tools.
- Integrated Safety Features: POR, BOR, and WDT provide fail-safe operation without external components.
- Wide Supply Range: Compatible with both 3.3V and 5V systems, increasing design flexibility.
Automated Assembly Lines
The tape-and-reel packaging (TR) is optimized for high-volume SMT production, making this variant ideal for mass-produced control modules.
Consumer Appliances
Use it in washing machine timers or microwave control panels. The 16 MHz speed handles user interface scanning and display refresh smoothly.
Power Tools
In battery-powered drills, the MCU manages trigger input and motor PWM, while the brown-out reset prevents sudden shutdowns during load spikes.
Smart Grid Devices
For smart meters or circuit breakers, the wide temperature range and robust I/O ensure reliable operation in outdoor enclosures.
LED Lighting Drivers
Generate high-frequency PWM for dimming and color mixing. The WDT ensures the light output remains stable even if the firmware encounters an error.
Industrial Sensors
Interface with 4-20mA loops or thermocouples, using the MCU's analog features to linearize and transmit data over a bus.
