{"product_id":"stm8al3138tcx","title":"STM8AL3138TCX","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-temperature tolerance (125°C) for harsh environments.\u003c\/li\u003e\n\u003cli\u003eLow voltage operation (1.65V) supports single-cell battery designs.\u003c\/li\u003e\n\u003cli\u003eDMA reduces CPU overhead for data transfer.\u003c\/li\u003e\n\u003cli\u003eMature STM8 architecture with extensive toolchain support.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eAutomotive Sensor Interfaces\u003c\/h3\u003e\u003cp\u003eThe 125°C rating and 16MHz STM8 core make it ideal for engine bay sensors like oil pressure or temperature, with WDT ensuring reliable operation.\u003c\/p\u003e\u003ch3\u003eIndustrial Actuators\u003c\/h3\u003e\u003cp\u003eWith PWM and DMA, the STM8AL3138TCX can drive small solenoid valves in process control, operating from 1.65V to 3.6V for low-power loops.\u003c\/p\u003e\u003ch3\u003ePortable Instrumentation\u003c\/h3\u003e\u003cp\u003eThe low voltage and 8KB flash suit handheld multimeters or thermocouple readers, with POR and brown-out reset protecting calibration data.\u003c\/p\u003e\u003ch3\u003eSmart Lighting Ballasts\u003c\/h3\u003e\u003cp\u003eThis MCU can manage LED driver feedback loops using its ADC and PWM, with the 48-LQFP package allowing compact PCB layouts.\u003c\/p\u003e\u003ch3\u003eBattery Management Systems\u003c\/h3\u003e\u003cp\u003eFor single-cell Li-ion packs, the 1.65V minimum supply enables direct operation, while DMA handles cell voltage monitoring without CPU intervention.\u003c\/p\u003e\u003ch3\u003eConsumer Appliances\u003c\/h3\u003e\u003cp\u003eIn washing machines or dishwashers, the STM8 core controls timers and display segments, with WDT preventing software hangs.\u003c\/p\u003e\u003ctable\u003e\n\u003ccolgroup\u003e\u003ccol\u003e\u003c\/colgroup\u003e \u003ctbody\u003e \u003ctr\u003e \t\u003ctd\u003eProduct attributes\u003c\/td\u003e \t\u003ctd\u003eProperty Value\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eManufacturer\u003c\/td\u003e \t\u003ctd\u003eSTMicroelectronics\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eProduct Series\u003c\/td\u003e \t\u003ctd\u003eSTM8A\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003ePackaging\u003c\/td\u003e \t\u003ctd\u003eTape \u0026amp;
