Overview
The STM8L151G6U6TR is a member of the STM8L ultra-low-power 8-bit microcontroller family from STMicroelectronics. This medium-density microcontroller operates within a voltage range of 1.65 to 3.6 V and is available in temperature ranges of -40 to 85 °C, 105 °C, or 125 °C. It 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 device 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.
