Product details

24 MHz core, 64 KB Flash — the BOM-fit tier for 8-bit control

The STMicroelectronics STM8S207M8T3B is an 8-bit MCU from the STM8S family, built around the STM8 core and clocked at 24 MHz.

68 I/O and serial connectivity — what the peripheral set covers

For a motor-drive or LIN-node design, that means you can run a sensor bus on I²C or SPI, handle debug or firmware updates over UART, and communicate on a LIN automotive network without an external transceiver controller — the LIN protocol is handled in the MCU's UART peripheral with the LIN break detection. The 68 I/O count, in an 80-pin LQFP package, leaves room for parallel LCD data buses or multiple switch/solenoid reads without port expansion.

The Vcc range spans 2.95 V to 5.5 V, so the same MCU can sit on a 3.3 V sensor board or a 5 V industrial backplane without a level shifter on the supply.

For a procurement decision, this removes the obsolescence risk that drives last-time-buy premiums and forces a requalification cycle.

Frequently asked questions

What is the closest pin-compatible alternative to STM8S207M8T3B in this family?

Pin-compatible variants within the STM8S family share the 80-LQFP footprint and peripheral set, but the exact alternate order code depends on the memory density and feature combination your firmware requires — the sourcing desk can confirm cross-reference options when you submit the RFQ with your target quantity and application requirements.

Who supplies STM8S207M8T3B and how is it quoted for volume purchases?

This order code is sourced through independent distribution and quoted to order against an RFQ — availability, pricing tier, and lead time are confirmed at quote time, with volume pricing reflected in the quote response.

What compliance documentation does ST provide for STM8S207M8T3B?

Standard STMicroelectronics RoHS/REACH declarations and industrial-grade conformance data apply to this part — the sourcing desk can provide the specific compliance documentation bundle with the RFQ response.
