Overview
The STM8L151G6U3 is a member of the STM8L ultra-low-power 8-bit microcontroller family from STMicroelectronics. This device is part of the medium-density STM8L15x series, known for its enhanced STM8 CPU core, which provides increased processing power of up to 16 MIPS at 16 MHz while maintaining the advantages of a CISC architecture. The microcontroller operates within a voltage range of 1.8 V to 3.6 V (down to 1.65 V at power down) and is available in temperature ranges of -40 to +85 °C and -40 to +125 °C.
The STM8L151G6U3 features an integrated debug module with a hardware interface (SWIM) for non-intrusive In-Application debugging and ultra-fast Flash programming. It includes embedded data EEPROM, low-power, low-voltage, single-supply program Flash memory, and an extensive range of enhanced I/Os and peripherals.
