The STM8L101G3U6 from STMicroelectronics is an ultra-low-power 8-bit microcontroller based on the STM8 core, operating at up to 16MHz. It provides 8KB of flash memory and 1.5KB of SRAM, with a supply voltage range of 1.65V to 3.6V. This device features an infrared interface, power-on reset, PWM, and watchdog timer. Packaged in a compact 28-pin UFQFN, it is designed for battery-powered and space-constrained applications, operating reliably from -40°C to 85°C.
- Ultra-Low Voltage Operation: 1.65V minimum allows direct battery operation without boost converters.
- Integrated IR Support: Reduces external components for remote control and proximity sensing.
- Compact Form Factor: 28-UFQFN package saves PCB space in miniaturized devices.
- Low Power Consumption: Optimized for extended battery life in portable and wearable electronics.
Ultra-Low-Power Wearables
With a 1.65V minimum supply and 16MHz STM8 core, it can run fitness trackers or smartwatches from a single coin cell, while the IR feature enables wireless data sync.
Remote Controls and IR Transmitters
The integrated infrared peripheral simplifies NEC or RC5 protocol encoding, reducing external components and BOM cost in TV or AC remotes.
Medical Patch Sensors
Its low voltage (1.65V) and small UFQFN package allow for disposable glucose or ECG patches that operate for weeks on thin-film batteries.
Smart Home Sensors
8KB flash is sufficient for temperature/humidity monitoring logic, while the WDT ensures reliable operation in always-on door/window sensors.
Portable Instruments
The 1.5KB RAM and low-power modes enable handheld multimeters or thermometers with long battery life and fast wake-up from sleep.
IoT End Nodes
With 16MHz processing and IR for proximity sensing, it can serve as a low-power edge node in smart building occupancy detection systems.
