Product details

16 MHz core, LCD drive, and a wide temperature span

The STMicroelectronics STM8L152C6U3 is an 8-bit microcontroller from the STM8L EnergyLite series, built around the STM8 core and clocked at 16 MHz.

Peripherals that replace external ICs

That means a single STM8L152C6U3 can handle analog sensing, serial communication, and display update without glue logic — the scorch mark on a dead board often traces back to a missing external LCD controller or level shifter that this part eliminates.

The 48-UFQFN exposed-pad package (7x7 mm) keeps the footprint small and the thermal path short when dissipating a few hundred milliwatts.

For a production BOM line or a repair depot stocking spares, that means you can qualify this part for new designs today without worrying about an abrupt end-of-life — the supply channel remains open through standard distribution and independent sourcing.

Frequently asked questions

Can STM8L152C6U3 drive an LCD directly?

Yes, the STM8L152C6U3 includes an integrated LCD driver peripheral, which can directly drive a segmented LCD panel without an external controller. This is a key differentiator for display-centric applications like metering and control panels.

STM8L152C6U3 vs STM8L152C6T6: what is the difference?

Both parts share the same core, memory, and peripheral set. The primary difference is the package: the STM8L152C6U3 comes in a 48-UFQFN exposed-pad package (7x7 mm), while the STM8L152C6T6 uses a 48-LQFP package. The UFQFN offers a smaller footprint and better thermal performance through the exposed pad, but requires a reflow profile suited to QFN packages. The LQFP variant is easier to hand-solder and inspect. Pin compatibility is not guaranteed — verify the footprint before swapping.
