Overview
The STM8L151K4U6TR is a member of the STM8L ultra-low-power 8-bit microcontroller family from STMicroelectronics. This medium-density MCU is designed to operate within a wide voltage range of 1.8 V to 3.6 V, and it 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. It also includes an integrated debug module with a hardware interface (SWIM) for non-intrusive In-Application debugging and ultra-fast Flash programming.
