7.1 USB
Jetson AGX Xavier supports up to four USB 2.0 ports and up to three USB 3.1 ports. There are
examples in this section to either implement a simple USB 3.1/2.0 connection to a USB 3.1
Type A connector or to replicate the USB Type C connections used on the NVIDIA Developer
Kit. Designs that intend to follow the NVIDIA Developer Kit carrier board design and include
the Type C PD Controller (CYPD4226) need to replicate the circuitry on the latest P2822 carrier
board exactly. NVIDIA will provide the binary and the customer should get the flashing
instructions from Cypress. If the design requires a simpler solution (Type A or similar), then
refer to the software adaptation guide for information.
Notes:
• Some non-compliant USB 3.1 devices may fail unless USB 3.1 Gen2 is disabled.
• See Section 15.1 “USB Recover Mode” for requirements for USB recovery mode.

Type C connections are based on the NVIDIA carrier board design. Additional interface
assignments shown in Figure 7-2 are also based on the carrier board usage.
Designs that intend to follow the NVIDIA carrier board design and include the Type C PD
Controller (CYPD4226 - U513 on NVIDIA carrier board) need to replicate the circuitry on the
latest P2822 carrier board exactly. NVIDIA will provide the binary and the customer should get
the flashing instructions from Cypress.
If the CYPD4226 PD controller is implemented in a design, it is recommended that test points
be included that connect to the
SW_CLK, SW_IO and XRES pins as well as VDD_AO. These would be
required to flash the binary during manufacturing.
