USB Interface

EZ-USB FX3 supports USB peripheral functionality compliant

with USB 3.0 Specification Revision 1.0 and is also backward

compatible with the USB 2.0 Specification.

EZ-USB FX3 is compliant with On-The-Go Supplement Revision

2.0. It supports Hi-Speed, Full-Speed, and Low Speed OTG dual

role device capability. It is SuperSpeed, High-Speed, and

Full-Speed capable as a peripheral and High-Speed, Full-Speed,

and Low-Speed capable as a host.

EZ-USB FX3 supports Carkit Pass-Through UART functionality

on USB D+/D- lines based on the CEA-936A specification.

EZ-USB FX3 supports up to 16 IN and 16 OUT endpoints.

EZ-USB FX3 fully supports the USB3.0 Streams feature. It also

supports USB Attached SCSI (UAS) device class to optimize

mass storage access performance.

As a USB peripheral, EZ-USB FX3 supports UAS, USB Video

Class (UVC), Mass Storage Class (MSC), and Media Transfer

Protocol (MTP) USB peripheral classes. As a USB peripheral, all

other device classes are supported only in pass through mode

when handled entirely by a host processor external to the device.

As an OTG host, EZ-USB FX3 supports MSC and HID device

classes.

When the USB port is not in use, the PHY and transceiver may

be disabled for power savings.

OTG

EZ-USB FX3 is compliant with the On-The-Go (OTG) Specifi-

cation Revision 2.0 .

In OTG mode, EZ-USB FX3 supports both A and B device mode

and supports Control, Interrupt, Bulk, and Isochronous data

transfers.

EZ-USB FX3 requires an external charge pump (either stand

alone or integrated into a PMIC) to power VBUS in OTG A-device

mode.

The Target Peripheral List for OTG host implementation consists

of MSC and HID class devices.

Attach Detection Protocol (ADP) is not supported by EZ-USB

FX3.
