Peripheral set and connectivity
On the communication side you get CAN 2.0B, I²C, LINbus, SPI, and two UART/USART channels — enough to bridge a CAN bus to a local sensor cluster or handle a LIN slave node without an external transceiver controller. Built-in brown-out detect, power-on reset, and a watchdog timer mean the part can run unsupervised in a vehicle environment where supply transients are routine.
That does not mean it has vanished from the channel — it is still available for existing production BOMs, but ST is steering new designs toward a successor.
