Product details

The STMicroelectronics STM8AL3148TCY is an 8-bit MCU from the STM8A automotive line, built around the STM8 core and clocked at 16 MHz. It carries 16 KB of Flash program memory, 2K x 8 of RAM, and 1K x 8 of EEPROM — enough for moderate control-loop firmware and non-volatile parameter storage.

NRND — not for new designs, but still sourced for production runs

That means ST is not actively promoting it for fresh BOMs, but it remains available for existing production lines through the independent channel.

It provides 41 I/O lines in a 48-LQFP package (7x7 mm body).

Frequently asked questions

What is the replacement for STM8AL3148TCY?

For a pin-compatible alternative within the STM8A family, check the current STM8A product selector — many STM8A devices share the 48-LQFP footprint and peripheral set. Qualify the alternate before committing the BOM.

Does STM8AL3148TCY have AEC-Q100 certification?

Yes, the STM8AL3148TCY is AEC-Q100 qualified, confirming its suitability for automotive-grade applications.
