STM8S105S4T6CTR ST Microcontroller

The STM8S105S4T6CTR is an 8-bit access-line medium-density MCU from STMicroelectronics in LQFP-44 package, operating at 16MHz with 16KB Flash, 2KB RAM, and 1KB true data EEPROM . For selection, verify supply from 2.95V to 5.5V, confirm -40°C to +85°C operation, note 34 I/Os, 10-bit ADC with up to 7 channels, communication interfaces including I2C (400kbit/s), SPI (8Mbit/s), UART with LIN/SmartCard/IrDA support, two 16-bit general purpose timers, advanced control timer with 3 complementary outputs for PWM, and independent watchdog . Features include nested interrupt controller with 32 vectors, clock security system, 96-bit unique ID, and robust 5V-tolerant I/Os. Ideal for industrial control, automotive body electronics (window lift, mirror control), consumer appliances, motor control (small BLDC, DC motors), and any general-purpose embedded application requiring cost-effective 8-bit performance with 5V operation and EEPROM integration .
