USB Interface

FX3S complies with the following specifications and supports the

following features:

■ Supports USB peripheral functionality compliant with the

USB 3.0 Specification Revision 1.0 and is also backward

compatible with the USB 2.0 Specification.

■ Complies with OTG Supplement Revision 2.0. It supports

High-Speed, Full-Speed, and Low-Speed OTG dual-role device

capability. As a peripheral, FX3S is capable of SuperSpeed,

High-Speed, and Full-Speed. As a host, it is capable of

High-Speed, Full-Speed, and Low-Speed.

■ Supports Carkit Pass-Through UART functionality on USB

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

■ Supports up to 16 IN and 16 OUT endpoints.

■ Supports the USB 3.0 Streams feature. It also supports USB

Attached SCSI (UAS) device-class to optimize mass-storage

access performance.

■ As a USB peripheral, FX3S 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 the pass-through

mode when handled entirely by a host processor external to

the device.

■ As an OTG host, FX3S supports MSC and HID device classes.

Note

When the USB port is not in use, disable the PHY and

transceiver to save power.

OTG

FX3S is compliant with the OTG Specification Revision 2.0. In

the OTG mode, FX3S supports both A and B device modes and

supports Control, Interrupt, Bulk, and Isochronous data

transfers.

FX3S requires an external charge pump (either standalone or

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

mode.

The Target Peripheral List for OTG host implementation consists

of MSC- and HID-class devices.

FX3S does not support Attach Detection Protocol (ADP).
