The STMicroelectronics STM8AL3138TCX is an 8-bit microcontroller based on the STM8 core, running at 16MHz. It provides 8KB flash and 2KB RAM, with a supply range of 1.65V to 3.6V. The 48-LQFP package offers moderate I/O for control applications. Integrated features include DMA, PWM, WDT, and brown-out detection. Its extended temperature range up to 125°C makes it suitable for automotive and industrial environments.
- High-temperature tolerance (125°C) for harsh environments.
- Low voltage operation (1.65V) supports single-cell battery designs.
- DMA reduces CPU overhead for data transfer.
- Mature STM8 architecture with extensive toolchain support.
Automotive Sensor Interfaces
The 125°C rating and 16MHz STM8 core make it ideal for engine bay sensors like oil pressure or temperature, with WDT ensuring reliable operation.
Industrial Actuators
With PWM and DMA, the STM8AL3138TCX can drive small solenoid valves in process control, operating from 1.65V to 3.6V for low-power loops.
Portable Instrumentation
The low voltage and 8KB flash suit handheld multimeters or thermocouple readers, with POR and brown-out reset protecting calibration data.
Smart Lighting Ballasts
This MCU can manage LED driver feedback loops using its ADC and PWM, with the 48-LQFP package allowing compact PCB layouts.
Battery Management Systems
For single-cell Li-ion packs, the 1.65V minimum supply enables direct operation, while DMA handles cell voltage monitoring without CPU intervention.
Consumer Appliances
In washing machines or dishwashers, the STM8 core controls timers and display segments, with WDT preventing software hangs.
