NRND status — plan the replacement now
It is not yet obsolete, but ST has signaled it will not be supported for new production programs. Buyers should qualify a pin-compatible replacement for ongoing builds; the STM8AF6288 (non-'DX' suffix) is the same base part and may serve as a drop-in alternative depending on package and temperature grade — verify the exact variant against your BOM.
Peripheral set and memory fit for body-control and sensor nodes
With 38 I/O lines, a 10-channel 10-bit ADC, and connectivity including I²C, LINbus, SPI, and UART/USART, this MCU handles the typical sensor aggregation and actuator drive found in automotive body controllers, sunroof modules, and HVAC blower controls. The 6 KB RAM and 2 KB EEPROM leave headroom for a modest RTOS or state-machine firmware without external memory.
