Cypress Semiconductor CY7C656xx Hub Controllers

Cypress Semiconductor CY7C656xx
USB 2.0 Hub Controllers

Cypress introduced CY7C656xx as part of its next generation HX2VL™ family of high performance, very low power USB 2.0 hub controllers. CY7C656xx USB 2.0 Hub Controllers are ideally suited for ultra low power, high performance applications that require up to four downstream ports. All downstream ports share a single transaction translator and are backward compatible with FS, LS. CY7C656xx USB 2.0 Hubs integrate 1.5 kohm upstream pull-up resistors for full speed operation and all downstream 15 kohm pull-down resistors and series termination resistors on all upstream and downstream D+ and D- pins. The design optimizes system costs by providing support for the USB 2.0 specification. The devices are available in the 48-pin TQFP and 28-pin QFN package options. Cypress offers reference design kits which include board schematics, bill of materials, Gerber files, Orcad files, and thorough design documentation to support CY7C656xx USB 2.0 Hub Controllers.
