CY7C65631-56LTXIT

CY7C65631-56LTXIT is a EZ-USB HX2LP Lite™ Cypress’s next generation family of high performance, low power USB 2.0 hub controller. HX2LP Lite is an ultra low power single chip USB 2.0 hub controller with 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 many external passive components such as pull up and pull down resistors, reducing the overall bill of materials required to implement a hub design. This device option is for ultra low power applications that require four downstream ports. All four ports share a single transaction translator. Typical applications are standalone hubs, motherboard hubs, monitor hubs, advanced port replicators, docking stations, split-PC designs, external personal storage drives, keyboard hubs.

• Compliant with the USB 2.0 specification, windows hardware quality lab (WHQL) compliant
• Up to four downstream ports supported, single transaction translator (TT)
• Supports bus powered and self powered modes, bus power configurations
• Single power supply requirement, internal regulator for reduced cost
• Integrated upstream pull-up resistor, integrated pull-down resistors for all downstream ports
• Integrated upstream and downstream termination resistors
• Integrated port status indicator control, in-system EEPROM programming
• 24MHz external crystal (integrated phase locked loop (PLL)), configurable with external SPI EEPROM
• 56-pin QFN 4-port package
