Product details

The STM8L151G6U6 is an 8-bit MCU from ST's STM8L EnergyLite series, built around the STM8 core running at 16 MHz. It packs 32 KB of program Flash, 2 KB of SRAM, and 1 KB of data EEPROM — enough for a moderate sensor node or control loop without external memory. The 1 KB EEPROM is useful for calibration constants or fault logs that survive power loss, separate from the Flash firmware image.

Analog on the die: 18-channel 12-bit ADC and a 12-bit DAC

A 12-bit ADC with 18 multiplexed channels and a single 12-bit DAC are integrated, so many designs can skip an external converter. The ADC covers enough inputs for a multi-sensor front-end (thermistors, current shunts, potentiometers), while the DAC can generate a reference or analog output for a display driver or actuator setpoint.

Frequently asked questions

Does STM8L151G6U6 have a built-in ADC?

Yes, it integrates an 18-channel 12-bit ADC and a single 12-bit DAC, both on-chip.

What are the alternatives to STM8L151G6U6?

The STM32L151CBU6A is a functional alternative with a 32-bit ARM Cortex-M3 core running at 32 MHz, more I/O (37), and USB connectivity, but it uses a different package (32-pin UFQFPN) and is not pin-compatible. For a direct 8-bit replacement within the same family, look at other STM8L151 variants with matching Flash and package.
