USB Interface
FX3 complies with the following specifications and supports the
following features:
■ Supports USB peripheral functionality compliant with USB 3.1
Specification Revision 1.0 and is also backward compatible
with the USB 2.0 Specification.
■ FX3 Hi-Speed parts (CYUSB201X) only support USB 2.0.
■ Complies with OTG Supplement Revision 2.0. It supports
High-Speed, Full-Speed, and Low-Speed OTG dual-role device
capability. As a peripheral, FX3 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 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, application examples show that the FX3
supports UAS, USB Video Class (UVC), and Mass Storage
Class (MSC) USB peripheral classes. All other device classes
can be supported by customer firmware; a template example
is provided as a starting point.
■ As an OTG host, application examples show that FX3 supports
MSC and HID device classes.
Note When the USB port is not in use, disable the PHY and
transceiver to save power.
OTG
FX3 is compliant with the OTG Specification Revision 2.0. In
OTG mode, FX3 supports both A and B device modes and
supports Control, Interrupt, Bulk, and Isochronous data
transfers.
FX3 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.
FX3 does not support Attach Detection Protocol (ADP).
OTG Connectivity
In OTG mode, FX3 can be configured to be an A, B, or dual-role
device. It can connect to the following:
■ ACA device
■ Targeted USB peripheral
■ SRP-capable USB peripheral
■ HNP-capable USB peripheral
■ OTG host
■ HNP-capable host
■ OTG device
