CYUSB3035
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).
