A USB hub controller is a system-on-chip that manages traffic between one upstream USB connection and multiple downstream USB ports. It belongs to the USB interface controller hierarchy, which combines USB transaction handling, port control, clock generation, and device interfacing in a single semiconductor. The HX2LP family is specifically oriented toward compact, low-power USB hub designs where board area and standby energy use are important design constraints.
The CY7C65631-56LTXCT provides four downstream hub ports and integrated upstream and downstream termination resistors. It also includes integrated port-status indicator control, an external 24 MHz crystal interface with an integrated PLL, and in-system EEPROM programming. These functions reduce the amount of external support circuitry and simplify firmware configuration in production equipment.
The controller uses a single-TT architecture in which downstream traffic is managed through a shared transaction translator. This architecture can simplify hub implementation and reduce external USB connectivity requirements. The 56-pin QFN package also provides a compact surface-mount footprint suitable for equipment panels, docking stations, desktop peripherals, and embedded USB distribution systems.
Typical uses include powered USB hubs, multi-port charging and data-distribution panels, kiosk systems, test fixtures, and USB expansion boards. Designers should account for the 0°C to 70°C temperature range when planning enclosure temperature, connector current requirements, cable losses, and thermal conditions around the QFN device.
PCB implementation requires close attention to USB differential-pair routing, crystal placement, termination-network integrity, and decoupling. Short matched traces and a compact ground return help preserve signal quality, while stable local supply bypassing reduces the chance of controller or downstream-port instability during hot-plug activity.
This product page consolidates the controller's electrical limits, package information, application fit, verified drop-in alternative, and design considerations into an engineering-focused reference. It supports component selection while directing detailed pin assignment and production-programming decisions to the manufacturer datasheet.

Talaan ng Disenyo
Route each USB 2.0 differential pair as a tightly coupled, impedance-controlled pair with a continuous ground reference. Avoid plane splits beneath the pairs, minimize stubs to connectors and test points, and keep the upstream and downstream routes away from clocks and switching-power nodes. Differential-pair geometry and spacing must be calculated from the board stack-up rather than copied from a generic layout.
Place the 24 MHz crystal, its load components, and the associated ground path directly beside the controller clock pins. Keep the crystal loop compact and isolate it from USB differential pairs and high-current port-power routing. Follow the manufacturer reference layout for crystal placement, grounding, and decoupling because oscillator stability and USB clock-jitter margin depend on those details.
Provide local 3.3 V decoupling at the controller's supply pins and separate the hub's downstream port-power distribution from sensitive logic paths. Confirm the hub's self-powered or bus-powered operating mode, downstream current budget, and protection strategy against the datasheet. Adequate supply headroom prevents voltage droop during simultaneous device connections and hot-plug events.
Do not treat a shared QFN package as proof of drop-in interchangeability. Compare every pin, supply sequence, clock requirement, termination implementation, EEPROM interface, port-power behavior, and programming procedure between the original and candidate device. Any connector, enclosure, or firmware change must be validated with USB compliance and enumeration tests before production release.
