Product details

16 MHz 8-bit core with EnergyLite architecture

The STMicroelectronics STM8L151C6U3TR is an 8-bit MCU from the STM8 EnergyLite series, built around the STM8 core running at 16 MHz. The 48-UFQFN exposed-pad package (7x7 mm) keeps the footprint compact for space-constrained industrial sensor nodes and portable instrumentation.

25 analog inputs and a 12-bit DAC on a single chip

With 25 multiplexed 12-bit ADC channels and a separate 12-bit DAC, this MCU handles multi-sensor acquisition and analog output generation without external converters.

It is appropriate for engine-bay electronics, outdoor telecom pole-top units, downhole instrumentation, and factory-floor motor drives where commercial-grade parts would fail.

Frequently asked questions

Is STM8L151C6U3TR equivalent to STM8L151C6T6?

The STM8L151C6T6 shares the same STM8 core, 16 MHz speed, 32 KB Flash, and 2 KB RAM, but comes in a different package (LQFP-48 vs UFQFN-48). The T6 variant is a common cross-reference for designs that prefer a QFP footprint. Verify the package compatibility and pinout against your PCB layout before substituting.

Is STM8L151C6U3TR obsolete or active?

The product status is Active. STMicroelectronics continues to manufacture this MCU with no announced end-of-life or last-time-buy schedule.
