EZ-USB FX3

SuperSpeed USB Controller

USB interface

3USB 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 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.

3.1

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).

3.1.1

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
