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.
