Overview
The STM8L152C8U6 is a member of the STM8L ultra-low-power 8-bit microcontroller family from STMicroelectronics. This device is part of the high-density and medium+ density STM8L15xx series, which features an enhanced STM8 CPU core. The core 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 STM8L152C8U6 operates from 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, 105, or 125 °C.
The device includes an integrated debug module with a hardware interface (SWIM) for non-intrusive in-application debugging and ultra-fast Flash programming. It also features embedded data EEPROM and low-power, low-voltage, single-supply program Flash memory.
