Ⅰ What is STM8S003F3P6?

STMicroelectronics' STM8S003F3P6 Value Line 8-bit microcontrollers offer 8KB of Flash program memory, as well as integrated true-data EEPROM. The STM8S003F3P6 Value Line devices offer the following benefits: performance, robustness, and reduced system cost. Real data EEPROM supports up to 100,000 write/erase cycles, advanced core, and peripherals manufactured with state-of-the-art technology with 16MHz clock frequency, powerful I/O, an independent watchdog with independent clock ensure device performance, and a Robust source and clock security system. System cost is reduced due to high system integration with the internal clock oscillator, watchdog, and brown-out reset.

Ⅻ  How to Select your STM Microcontroller?

Microcontrollers from the STM8 family are available in a wide range from STMicroelectronics. Each MCU has unique benefits and drawbacks. Before choosing an MCU for a project, one must take into account a number of factors. The following ideas are merely suggestions that might aid in MCU selection.

A fantastic choice for a novice learning STM8 series microcontroller is an MCU with strong online community assistance and a broad range of applications. In that situation, STM8S103F3P6 is a wise choice. The STM8 series features a helpful online support community provided by STMicroelectronics.

Think about the system's operating voltage. Choose a 5V MCU if they are 5V. In these situations, a 3.3V MCU can be chosen. Some sensors or devices operate and communicate on 3.3V.

Small 8-pin MCUs like the STM8S001J3 are an option if cost and size are constraints. These are also considerably less expensive.

Verify which MCU modules you might require based on the sensors and actuators utilized in your project. For instance, if you need to read a lot of analog voltages, check that the STM8S103F3P6 series microcontroller you choose has adequate ADC channels and a good resolution.

Check to see if your STM8 microcontroller can support all of the communication protocols your project requires, such as UART, SPI, I2C, CAN, etc. Some MCUs are capable of supporting many modules for the same protocol.
