Infineon CY7C65621-56LTXCT, USB Controller, USB 2.0, 3.15 to 3.45 V, 56-Pin QFN

The Infineon USB 2.0 hub controllers is an ultra low power single chip USB 2.0 hub controller with integrated upstream and downstream transceivers. USB 2.0 Hubs are high performance, low system cost solutions for USB. The Hubs integrate 1.5 kilo ohm upstream pull up resistors for full speed operation and all downstream 15 kilo ohm pull down resistors. This results in optimization of system costs by providing built in support for the USB 2.0 specification.
