16 MHz 8-bit core with segment LCD drive
The STMicroelectronics STM8L152K4T6 is an 8-bit MCU from the STM8L EnergyLite series, built around the STM8 core running at 16 MHz. What sets this part apart in the 8-bit landscape is the integrated segment LCD controller — it drives glass LCD panels directly, saving a separate display driver IC and the board area it would consume. The 12-bit ADC resolves 21 analog inputs, and a single 12-bit DAC is also on-chip, covering mixed-signal outputs without an external converter.
Peripheral set for metering and human-machine interface
Beyond the LCD driver, the peripheral list includes brown-out detect and reset, DMA, infrared (IrDA), PWM, and a watchdog timer. The 29 I/O lines in the 32-LQFP package leave room for a keypad matrix or a few external sensors alongside the display segments. The 12-bit ADC with 21 multiplexed channels suits multi-sensor data acquisition — think temperature, pressure, and humidity on one die. The single 12-bit DAC can drive an analog gauge or a speaker for audible alerts.
Active lifecycle — no end-of-life clock ticking
There is no NRND notice, no last-time-buy date, and no official successor part number published. The ROHS3 compliance covers the EU regulatory requirement without an exemption expiry to track.
