128 KB Flash, 24 MHz core — the cost-optimized control tier
The STMicroelectronics STM8S208MBT6B is an 8-bit MCU from the STM8S series, built around the STM8 core and running at 24 MHz.
The wide supply range (2.95 V to 5.5 V) means this MCU can be powered from a 5 V regulated rail without a level shifter for most I/O, simplifying the power tree and reducing component count.
80-LQFP package — footprint and rework considerations
The 80-LQFP package is a fine-pitch SMD footprint (0.5 mm pitch typical for this body size). It is reworkable with hot air, but the board should be designed with a solder mask defined pad geometry and a stencil aperture that matches the land pattern.
There is no last-time-buy clock running on this part.
The CAN and LIN interfaces are a strong match for automotive body-domain nodes — door modules, seat controllers, lighting — where the 8-bit cost structure is preferred over a 32-bit part.
