USB Host/Device

  Signal Name Recommended Pin Connection Description
 
  VBG 0.9 - 1.1V (1) (2) Bias Voltage Reference for USB

To reduce the noise on the VBG pin to a minimum, implement the layout considerations below:

- Keep the VBG path as short as possible

- Ensure a ground connection to GNDUTMI

VBG can be left unconnected if USB is not used.

  HSDM / HSDP Application dependent (1) (2) USB High Speed Data

Pulldown output at reset.

Notes:
  1. 1.The following schematic shows an example of USB High Speed host connection. For more information, refer to USB High-Speed Interface (USBHS)
  2. 2.The following schematic shows a typical USB High Speed device connection: For more information, refer to USB High-Speed Interface (USBHS).
Note: The values shown on the 22 kΩ and 15 kΩ resistors are only valid with 3.3V supplied PIOs.
