Product details

16 MHz 8-bit core with integrated LCD and analog peripherals

The STMicroelectronics STM8L152K4U6 is an 8-bit MCU from the STM8L EnergyLite series, built around the STM8 core running at 16 MHz. It packs 16 KB of Flash program memory, 2 KB of RAM, and 1 KB of EEPROM — enough for sensor fusion, metering, or human-interface control loops. The standout feature is the integrated LCD driver, which drives segment displays directly without an external controller, paired with a 21-channel 12-bit ADC and a single 12-bit DAC for analog signal chains.

Frequently asked questions

Does STM8L152K4U6 have an internal oscillator and LCD driver?

Yes. The MCU includes an internal oscillator and an integrated LCD driver peripheral, so segment displays can be driven directly without an external controller or crystal for the core clock.

What are the key differences between STM8L152K4U6 and STM8L151K4U6?

The primary difference is the LCD driver: the STM8L152K4U6 includes an integrated LCD driver, while the STM8L151K4U6 does not. Both share the same 16 MHz core, 16 KB Flash, 2 KB RAM, 1 KB EEPROM, and 21x12-bit ADC. For designs requiring a segment display, the STM8L152 variant saves an external LCD controller.
