New USB 2.0 Hub Controller From Cypress

Permalink: New USB 2.0 Hub Controller From Cypress

Cypress Semiconductor has launched its USB 2.0 hub controllers. The EZ-USB HX2LP controller, the member of the EZ-USB LP family, is optimized for applications such as standalone hubs, monitors, docking stations, keyboards and motherboards.

The EZ-USB HX2LP is USB-IF and Windows Hardware-quality lab (WHQL)-compliant. It is available in four-port (CY7C65630-56LFXC) and two-port (CY7C65620-56LFXC) options.

The device includes many external passive components, including pull-up and pull-down resistors and gang port power control to reduce the overall bill-of-materials required to implement a hub design. The EZ-USB HX2LP supports bus-powered and self-powered modes.

The product is available in a small form factor 56-pin QFN package that is backward compatible with Cypress’s TetraHub controller. The EZ-USB LP family uses advanced process technology developed by Cypress to reduce power consumption by nearly 50%.

As a result of the low dynamic power, peripherals using the devices can operate from the power of the USB bus. The low standby current enables portable USB applications to significantly extend battery life.
