2.3 USB interface
The target MCU (MCXN947) features two USB modules (FS USB and HS USB), each with device and host
capabilities and a built-in transceiver.
On the FRDM-MCXN947 board, only the HS USB controller and PHY interface is used and it is connected to
USB Type-C connector (J11).
Figure 9 shows the HS USB circuit diagram.

Table 11 describes the devices used for connection between HS USB controller and USB Type-C connector.
Part identifier Connector type Description
J11 USB2.0 Type-C
connector
Port can connect in both Host and Device mode. In Device mode, this port
provides the 5 V power supply (P5V_USB_HS) source to the board.

• ADR/CON_DET pin configuration:
– When pull up to P3V3_PTN with 10 kΩ resistor (R40), ADR (input) function:
ADR=1: I2C Address: 0x7A (ADR)
– When pull down to GND with 10 kΩ resistor (R49), ADR (input) function:
ADR=0: I2C Address: 0x3A (ADR)
– ARD=Mid/Floating (default setting), this pin automatically switches from
input to CON_DET output in non-I2C mode after TINPUTLATCH
– CON_DET (output) function:
– CON_DET=1: Connected detected
– CON_DET=0: No connection
• PORT pin configuration:
– When pull up to P3V3_PTN with 10 kΩ resistor (R42), PORT=1: DFP mode
– When pull down to GND with 10 kΩ resistor (R50), PORT=0: UFP mode
– When Floating (default setting): DRP mode
