| Overview
Cypress offers CY4607CY4607 HX2VL very low-power USB 2.0 compliant 4-Port hub development kit for developing a fixed-function, very low-power 4-port USB 2.0 hub that is production ready and USB-IF compliant.
HX2VL
The Cypress HX2VL uses 16 bytes of configuration settings, which define how the part interacts with the attached USB device(s) and the USB host. The HX2VL also uses a standard set of USB string descriptors to provide information about the product to the USB host. The HX2VL contains default configuration settings in its internal ROM. Circuit designs using the Cypress HX2VL may store the configuration settings and USB string descriptors externally on a I2C or SPI EEPROM.
The CY7C6563XCY7C6563X is a part of the HX2VL portfolio. This device option is for ultra low power but high performance applications that require up to four downstream ports. All downstream ports share a single transaction translator.
Key Applications: Docking stations, Standalone hubs, Monitor hubs, Multi-function printers, Digital televisions, Advanced port replicators, Keyboard hubs, Gaming consoles | |||||||||||

Cypress HX2VL Configuration Utility Blaster:
The Cypress HX2VL uses 16 bytes of configuration settings, which define how the part interacts with the attached USB device(s) and the USB host. The HX2VL also uses a standard set of USB string descriptors to provide information about the product to the USB host. The HX2VL contains default configuration settings in its internal ROM. Circuit designs using the Cypress HX2VL may store the configuration settings and USB string descriptors externally on a I2C or SPI EEPROM.
HX2VL supports field-programming of the I2C EEPROM connected to it. The Cypress HX2VL Configuration Utility Blaster is used to edit the configuration settings and USB descriptors for the HX2VL stored in the I2C EEPROM. The configuration settings and USB string descriptors can be stored in a HX2VL config (.iic) file on the PC, or the utility can work directly with settings and descriptors from the I2C EEPROM of a USB-attached HX2VL-based hub.
The utility is intended to give developers an opportunity to develop an optimal set of HX2VL configuration settings and USB string descriptors by experimenting with those settings and descriptors on their product. Once an optimal configuration is developed, it can be used with the utility for mass production.
