Product details

Automotive-grade 8-bit MCU with rich analog integration

The part integrates a 25-channel 12-bit ADC and a dual 12-bit DAC, plus peripherals including DMA, PWM, brown-out detect, and a watchdog timer.

NRND — plan a replacement path

This means STMicroelectronics no longer targets it for new-project wins, though existing production runs may still be supported for a time.

At 16 MHz, this 8-bit core handles typical automotive body-control loops — window lift, mirror adjust, seat memory — without breaking a sweat.

Analog front-end integration reduces BOM

This integration shrinks the PCB area and simplifies the analog supply filtering — a clear advantage for space-constrained automotive modules.

Frequently asked questions

Is STM8AL3L88TAY obsolete?

Existing production may still be supported; check the latest PCN for end-of-life timing.

What is the replacement for STM8AL3L88TAY?

An official successor is not listed in the current lifecycle record. For new designs, evaluate a pin-compatible STM8A-family MCU with similar Flash and analog resources — consult the STM8A cross-reference guide or contact us for a qualified alternative.

Can STM8AL3L88TAY be used in new automotive designs?

Technically yes, but the NRND status makes it a risk for long production runs. For a new automotive project, select a current-production STM8A or STM8AF part to avoid a mid-lifecycle redesign.
