【STSTM8L151/152】

STM8L151/152 is the performance line of our STM8L ultra-low-power family. These MCUs offer more performance and features compared to STM8L101.

Based on our 16 MHz proprietary STM8 core, they offer up to 64 Kbytes of Flash program memory, 4 Kbytes of SRAM and up to 2 Kbytes of data EEPROM in various packages from 20 to 80 pins. Analog features such as a 12-bit ADC and DAC, LCD controller and temperature sensors can be selected.

【STM8L151C2】

Ultra-low-power 8-bit MCUs with 4-Kbyte Flash, 16 MHz CPU, integrated EEPROM

The low-density STM8L151x2/3 ultra-low-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.

The family includes an integrated debug module with a hardware interface (SWIM) which allows non-intrusive in-application debugging and ultrafast Flash programming.

All low-density STM8L151x2/3 microcontrollers feature embedded data EEPROM and low-power low-voltage single-supply program Flash memory.

The devices incorporate an extensive range of enhanced I/Os and peripherals, a 12-bit ADC, two comparators, a real-time clock, two 16-bit timers, one 8-bit timer, as well as standard communication interfaces such as an SPI, an I2C interface, and one USART. The modular design of the peripheral set allows the same peripherals to be found in different ST microcontroller families including 32-bit families. This makes any transition to a different family very easy, and simplified even more by the use of a common set of development tools.
