CY7C65631-56LTXCT Übersicht
Infineon Technologies CY7C65631-56LTXCT is a four-port USB 2.0 hub controller based on the EZ-USB HX2LP Lite low-power controller family. The device operates from a 3.3 V supply, supports a single-TT hub configuration, and is packaged in a 56-pin QFN measuring 8 mm by 8 mm. Its specified commercial temperature range is 0°C to 70°C.
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.

The exact land pattern, exposed-pad arrangement, pin numbering, and soldering requirements must follow the package drawing in the manufacturer datasheet.
What is the operating voltage of CY7C65631-56LTXCT?
The CY7C65631-56LTXCT operates from a 3.3 V supply. The manufacturer product information identifies a 3.3 V operating supply and the EZ-USB HX2LP Lite low-power hub controller family. Confirm the permitted supply tolerance, internal regulator arrangement, and decoupling values in the datasheet before finalizing the power tree.
What is the operating temperature of CY7C65631-56LTXCT?
The CY7C65631-56LTXCT is specified for an operating temperature range of 0°C to 70°C. Infineon describes the ordering variant as I-grade, consistent with an industrial-commercial temperature class. This range should be checked against the enclosure's worst-case internal temperature when the hub operates next to a power supply or other heat-generating circuitry.
What features are integrated into CY7C65631-56LTXCT?
The CY7C65631-56LTXCT integrates upstream and downstream USB termination resistors, port-status indicator control, and an in-system EEPROM programming function.

Auswahlhilfe
Choose CY7C65631-56LTXCT for a compact four-port USB 2.0 hub that requires a single-TT architecture, 3.3 V operation, integrated termination resistors, port-status control, a 24 MHz crystal with an integrated PLL, and in-system EEPROM programming. Its 56-pin 8 mm by 8 mm QFN is appropriate for space-constrained hub panels, docking equipment, and embedded USB distribution products. Consider the CY7C65630-56LTXC only after a complete pin, feature, clocking, and firmware review; matching package size and supply voltage do not by themselves prove interchangeability. For applications outside 0°C to 70°C or requiring a different port count, select a controller whose specified electrical limits, protection features, and documentation directly match the system requirements.

Designhinweise
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.
