CY7C65642-28LTXCT

HX2VL is 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. External components such as voltage regulator and pull-up/pull-down resistors are also integrated, reducing the overall BOM required to implement a USB hub system. The CY7C65642 is a part of the HX2VL portfolio with four downstream ports and an independent TT dedicated for each downstream port. This device option is for low-power but high-performance applications that require up to four downstream ports. The CY7C65642 is available in 48-pin TQFP and 28-pin QFN package options.
