STM8L051F3 is member of the STM8L ultra-low-power 8-bit family.
●STM8L051F3 features an enhanced STM8 CPU core providing increased processing power (up to 16 MIPS at 16 MHz) while maintaining the advantages of a CISC architecture with improved code density, a 24-bit linear addressing space and an optimized architecture for low power operations.
●The STM8L051F3 MCU includes an integrated debug module with a hardware interface (SWIM) which allows non-intrusive In-Application debugging and ultra-fast Flash programming. It features an embedded data EEPROM and low power, low-voltage, single-supply program Flash memory.
●The device incorporates an extensive range of enhanced I/Os and peripherals, a 12-bit ADC, a real-time clock, two 16-bit timers, one 8-bit timer, as well as standard communication interfaces such as an SPI, an I2C interface, and one USART.
●The modular design of the peripheral set allows this device to have the same peripherals that can be found in different ST microcontroller families including 32-bit families. This makes any transition to a different family very easy, supported also by the use of a common set of development tools.
●STM8L051F3 as all the value line STM8L ultra-low-power products are based on the same architecture with the same memory mapping and a coherent pinout.
