STM8S003F3U6TR ST 8-bit MCU STM8S Microcontroller 16MHz 8KB (8K x 8) FLASH
The STM8S003F3U6TR, a cost-effective 8-bit microcontroller from STMicroelectronics' STM8S Value Line family, is housed in a compact 20-UFQFPN surface-mount package, designed to deliver robust performance and rich peripherals for cost-sensitive industrial control and consumer applications. Its key features include a rich set of peripherals: 16-bit advanced control timer with three complementary PWM outputs, 8-bit general-purpose timer, watchdog timer, UART, SPI, I²C interface, and a 10-bit ADC with up to 5 channels for analog signal acquisition. Operating from a wide 2.95 V to 5.5 V supply voltage with a robust I/O structure tolerant to 5 V, it supports multiple low-power modes including Active-halt with 350 nA typical current consumption and Halt mode with 290 nA typical, extending battery life in power-constrained designs. Fully supported by ST's comprehensive development ecosystem including STM8Cube IDE, standard peripheral library, and low-cost ST-LINK debugger/programmer, and rated for an extended -40°C to 85°C industrial temperature range, it is widely deployed in home appliances, motor control, battery chargers, LED lighting, power tools and simple sensor interfaces that demand reliable 8-bit control at minimal system cost.
