HX2VL (CY7C65642/32/34)
HX2VL is Cypress’s next generation family of high-performance, ultra low-power USB2.0 hub con-
trollers. Cypress HX2VL has integrated external components such as a 5 V to 3.3 V regulator and
pull-up/pull-down resistors. It provides the option of configuring through SPI/I2C EEPROM or GPIO
settings reducing the overall bill of materials.
HX2VL portfolio has two and four port, single and multiple TT options, and is capable of supporting
both self-powered and bus-powered hub designs. It is also available in space saving 48-pin
(7×7 mm) TQFP and 28-pin (5×5 mm) QFN packages.
1.3
Host Controller Hardware and Software
Latest PCs are pre-configured with high-speed USB support. All major operating systems come with
in-built hub (driver) support. Therefore, you can start working with the HX2VL right away.
Some host controllers obtained from third-party vendors, may have drivers with the add-in card.
Contact your supplier for more information.

Set Up the HX2VL CY4608/CY4608M Hardware
Due to the hot-plug nature of USB, hardware setup is easy.

shows the CY4608M, based on the 28-QFN of CY7C65642; CY4608 is based on 28-QFN of
CY7C65632. Determine if the hub design is a bus-powered or self-powered hub. A bus-powered hub does
not require any change.
