Product details

8-bit automotive MCU with extended temperature range

It runs at 16 MHz from a 1.65 V to 3.6 V supply, with 64 KB of Flash program memory, 4K x 8 RAM, and 2K x 8 EEPROM.

For a BOM already using this MCU, the NRND flag signals that a last-time-buy window or eventual discontinuation may follow.

16 MHz core — throughput for control loops

The 16 MHz clock rate is the ceiling for this 8-bit STM8 core. It delivers enough throughput for real-time sensor acquisition and actuator control in automotive body electronics, LIN node controllers, and DC motor drivers. The 12-bit ADC at 25 channels can sample multiple analog inputs without an external mux, reducing BOM count.

Frequently asked questions

What is a direct replacement for STM8AL3188TCX?

The STM8AL3188TCY is the direct pin-compatible replacement, sharing the same 48-LQFP package, 64 KB Flash, 16 MHz core, and peripheral set.

What is the operating temperature range of STM8AL3188TCX?

The STM8AL3188TCX is rated for -40°C to 125°C, covering automotive under-hood and industrial extended-temperature environments.

Where can I buy STM8AL3188TCX?

We source the STM8AL3188TCX to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm quote.

What does NRND mean for STM8AL3188TCX?

NRND means ST no longer recommends this MCU for new designs. It is still available for existing production, but a last-time-buy or EOL notice may follow. The STM8AL3188TCY is the recommended replacement.

Is STM8AL3188TCX pin-compatible with STM8AL3188TCY?

Yes, the STM8AL3188TCY is pin-compatible in the same 48-LQFP package, with identical memory and peripheral mapping.
