Frequently asked questions
Does the STM32F446ZCH7 need external PHY components for USB OTG and CANbus?
USB OTG is on-die at the controller level but requires an external PHY to complete the USB signal path — the physical-layer transceiver is not integrated in this variant. CANbus similarly needs an external ISO 11898-compliant transceiver to interface the on-chip CAN peripheral to the physical bus. Both are standard BOM additions for any industrial design using these interfaces, not hidden surprises.
