STM8L151K4T6 Description

The STM8L151K4T6 medium-density device is a part of the STM8L series of ultra-low-power 8-bit devices. The medium-density STM8L15x family is available in the temperature ranges of -40 to +85 °C and -40 to +125 °C, and it works from 1.8 V to 3.6 V (down to 1.65 V at power down).

The enhanced STM8 CPU core of the medium-density STM8L151K4T6 ultra-low-power family offers increased processing power (up to 16 MIPS at 16 MHz) while maintaining the benefits of a CISC architecture with improved code density, a 24-bit linear addressing space, and optimized architecture for low power operations.

The family has an embedded debug module with a hardware interface (SWIM) that enables ultra-quick Flash programming and non-intrusive In-Application debugging.

All medium-density STM8L15x microcontrollers have low-power, low-voltage, single-supply program Flash memory and inbuilt data EEPROM.

They include a wide variety of improved I/Os and peripherals.

The peripheral set's modular construction enables the use of the same peripherals across many ST microcontroller families, including 32-bit generations. This makes switching to a new family quite simple, and using a standard set of development tools makes it much simpler.

Six distinct packages, ranging from 28 to 48 pins, are suggested. There are several sets of peripherals included depending on the device selected.

The architecture, memory mapping, and pinout are all the same across all STM8L ultra-low-power products.
