Its 16 MHz STM8 core, integrated memory, timers, ADC, watchdog functions, and serial interfaces provide a practical platform for general-purpose embedded control. Current ST product information identifies the STM8S003F3P6TR as an active TSSOP-20 industrial-grade product with Ecopack2 compliance.
Applications of STM8S003F3P6TR
The STM8S003F3P6TR is suitable for embedded control systems that require compact integration, reliable processing, and multiple peripheral interfaces, including:
Industrial Control: Suitable for control panels, small automation controllers, and embedded monitoring functions.
Motor and Actuator Control: Its timers, PWM capabilities, and control-oriented peripherals can support motor-control and actuator applications.
Consumer Electronics: Can be integrated into appliances, user-interface controls, and compact electronic control boards.
Sensor and Measurement Systems: The integrated 10-bit ADC with up to five external multiplexed channels supports analog signal acquisition and monitoring.
Embedded Communication: UART, SPI, and I²C interfaces support communication between the MCU and external peripherals or system modules.
Package Information of ST STM8S003F3P6TR
The STM8S003F3P6TR uses a 20-pin TSSOP package with a 0.65 mm pitch. The STM8S003F3 family is also available in UFQFPN20 and other package variants, allowing designers to select a package according to board-space and I/O requirements.
For the P6TR ordering code, P identifies the TSSOP package, 6 specifies the -40°C to +85°C temperature range, and TR indicates tape-and-reel packaging.

Alternatives for STM8S003F3P6TR
If the STM8S003F3P6TR becomes unavailable or lead times increase, customers may consider related STM8S003F3 family options:
STM8S003F3U6TR: A related 20-pin STM8S003F3 variant using a compact UFQFPN20 3 × 3 mm package. It retains the 8 KB Flash, 1 KB RAM, 128-byte EEPROM, and 16 MHz STM8 architecture, but the package footprint and PCB layout are different.
STM8S003K3T6TR: A 32-pin STM8S003K3 variant offering up to 28 GPIOs, compared with 16 GPIOs on the STM8S003F3, making it relevant where additional I/O is required. It uses an LQFP32 package, so PCB and pinout compatibility must be verified.
