Overview
The STM8L151K4T6 is a member of the STM8L ultra-low-power 8-bit microcontroller family from STMicroelectronics. This medium-density MCU 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 device features the 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 with improved code density and a 24-bit linear addressing space. The STM8L151K4T6 is designed for low-power operations and includes an integrated debug module with a hardware interface (SWIM) for non-intrusive In-Application debugging and ultra-fast Flash programming.
