Cypress Semiconductor CY7C65642-48AXCT, USB Controller, 4-Channel, 12Mbps, USB 2.0, 5 V, 48-Pin TQFP

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 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. All device options are supported by Cypress’s world class reference design kits, which include board schematics, BOM, Gerber files, Orcad files, and thorough design documentation.
