Features and Applications

The STM8L152R8T6 is a Ultra-low-power 8-bit Microcontroller with 64 Kbytes Flash, 16 MHz CPU, integrated EEPROM. The family includes an integrated debug module with a hardware interface (SWIM) which allows non-intrusive in-application debugging and ultrafast Flash programming.

The high density and medium+ density STM8L15xx Ultralow power devices feature an enhanced STM8 CPU core providing increased processing power (up to 16 MIPS at 16 MHz) while maintaining the advantages of a CISC architecture with improved code density, a 24-bit linear addressing space and an optimized architecture for low power operations.
