CY4603: 4-Port USB 3.0 Hub

CY4603 is the development kit (DVK) for CYUSB3314-88LTXC, an advanced 88-QFN, 4-port USB 3.0 hub controller from Cypress. The hub controller supports Low-Speed (LS), Full-Speed (FS), Hi-Speed (HS) and SuperSpeed (SS) peripherals on all the four downstream ports. It supports status LEDs and individual power control for all the four downstream ports. It goes into suspend state to save power when the upstream port is not connected to a PC / laptop. All the downstream ports are compliant to USB Battery Charging Specification v1.2; they also emulate Apple charging. The hub controller also supports Ghost Charging, a unique feature where the downstream ports emulate Dedicated Charging Port (DCP) to support battery charging even when the upstream port of the board is not connected to a PC / laptop.

The hub controller can be configured for parameters such as vendor ID, product ID, etc. using a Windows based PC tool named Blaster Plus. The configured values are stored in an on-board EEPROM.

The hub controller can also be configured using pin straps which are implemented as jumpers on the board. Parameter such as vendor ID, number of removable ports, etc. can be configured using these jumpers. More details can be found in the kit user guide. To access the Blaster Plus tool, the kit user guide, and the hardware design files, download the DVK EXE file (CY4603HX3DVKSetup.exe) from https://www.infineon.com/cms/en/product/evaluation-boards/cy4603/. Click the EXE file and follow the steps in the installer window.
