Features & Applications

The CY7C65632-28LTXC is a HX2VL™ Cypress’s next generation family of high performance, very low power USB 2.0 hub controllers. HX2VL has integrated upstream and downstream transceivers; a USB Serial Interface Engine (SIE); USB Hub Control and Repeater logic; and Transaction Translator (TT) logic. Cypress has also integrated external components such as voltage regulator and pull-up/pull-down resistors, reducing the overall bill of materials required to implement a USB hub system.

The CY7C6563X 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. The CY7C6563X is available in 48-pin TQFP and 28-pin QFN package options.
