CY7C65620-56LFXA Présentation
A USB hub controller is an interface integrated circuit that coordinates communication between one upstream USB host connection and multiple downstream USB ports. Within the broader hierarchy, it is a USB interface IC, then a USB controller, and ultimately a semiconductor used to expand USB connectivity. Hub controllers commonly include port-management logic and configurable GPIO resources, although the exact feature set and firmware requirements must be confirmed from the manufacturer datasheet.
The verified listing describes the CY7C65620-56LFXA as an EZ-USB HX2LP low-power USB 2.0 hub controller. Mouser identifies it as a USB interface IC, while LCSC reports an in-stock status and a price from $0.3457. These listings support commercial availability information, but they do not provide a complete verified specification set for implementation. The product is therefore best treated as a procurement and package-level reference until the full datasheet is reviewed.
The Infineon product-page result for the related CY7C65620-56LTXC describes a configurable two-port single-TT hub with GPIO, LED-indicator, and EEPROM configuration options. That information describes the related ordering variant and should not be transferred automatically to the CY7C65620-56LFXA without checking the exact datasheet ordering table. Engineers should verify electrical limits, pin names, exposed-pad requirements, clocking, power sequencing, and USB signal-routing guidance before layout release.
Typical uses include USB hubs, USB monitors, docking stations, embedded USB expansion systems, and compact peripheral equipment. In these applications, the controller’s principal value is integration: it reduces the discrete logic required to manage multiple USB downstream ports while keeping the implementation within a compact QFN footprint.
The main design consideration is package and signal integrity. A 56-QFN controller requires a footprint-compatible land pattern, controlled power and ground distribution, and careful routing of USB differential pairs. Because the supplied data does not expose complete pin-level or electrical details, every board design must follow the official manufacturer datasheet rather than relying on distributor snippets.
This page consolidates verified distributor listings, related manufacturer information, package identity, pricing availability, and design-oriented cautions. It does not invent missing electrical specifications, pin names, timing values, or alternatives; the validation markers identify information that still requires manufacturer-documentation review.

Applications typiques
CY7C65620-56LFXA convient pour 6 applications: Compact USB 2.0 Hub, USB Docking Station, Embedded USB Expansion, Industrial USB Monitoring, USB Perimeter and Status Control, USB Test and Measurement Fixture.
Compact USB 2.0 Hub
The CY7C65620-56LFXA is identified as a low-power USB 2.0 hub controller, making it a logical central device for a compact hub that connects one upstream USB connection to downstream peripherals. Its 56-QFN package supports dense implementations where connector placement and board area are constrained. The engineer must confirm the exact downstream-port count, power requirements, configuration method, and pin-level routing in the manufacturer datasheet before selecting the device. The main design benefit is integration: compared with a discrete USB hub implementation, an integrated controller can reduce the number of separate control components and simplify firmware coordination. However, the supplied data does not provide input-current limits, USB impedance targets, or port-count specifications, so those values must not be inferred from the controller name.
Recommandé
USB Docking Station
A docking station can use the CY7C65620-56LFXA as the USB 2.0 hub controller when several external peripherals need to share a host connection. The 56-QFN footprint leaves board area available for power conversion, data protection, status indicators, and connector mechanics. Because the verified material does not specify operating voltage, hub-port current, or configuration pins, the power tree and USB routing should be designed from the official device documentation rather than assumed from distributor descriptions. The controller is particularly useful when the design needs integrated hub behavior rather than a collection of unrelated USB switches. Validate enumeration behavior, suspend and resume requirements, ESD strategy, and downstream-port power management during prototype testing.
Recommandé
Embedded USB Expansion
The CY7C65620-56LFXA can serve as the USB expansion element in an embedded system that needs standardized host connectivity. Integrating the hub function close to the connector may simplify the mechanical arrangement of a control board and keep USB routing localized. The verified data establishes the device as a low-power USB 2.0 hub controller, but it does not expose the complete electrical table or firmware interface. Engineers should verify whether the chosen firmware and host software support the exact configuration, then reserve continuous ground planes and controlled-impedance routing beneath differential pairs. A hardware prototype should also test hot-plug, enumeration, over-current response, and cable compatibility across the intended operating environment.
Recommandé
Industrial USB Monitoring
In industrial monitoring equipment, a USB hub controller can provide a controlled interface between a host computer and field-service peripherals such as data loggers, programmers, or measurement modules. The CY7C65620-56LFXA’s low-power positioning may help designers target compact instrumentation, although no measured current value is provided in the verified excerpts. The 56-QFN package also requires careful assembly planning because exposed-pad and thermal details must follow the exact package drawing. For industrial use, review ESD immunity, operating-temperature limits, grounding, isolation, and long-cable behavior from the manufacturer documentation. Do not infer industrial or automotive qualification from the Infineon/CYPRESS branding alone; the verified data does not state AEC-Q100 status.
Recommandé
USB Perimeter and Status Control
The related CY7C65620-56LTXC description identifies configurable GPIO, LED-indicator, and EEPROM options for a USB hub configuration. A design based on the CY7C65620-56LFXA may likewise need status indicators or port-management signals, but those features must be verified against the target MPN’s own datasheet rather than copied from the LTXC listing. This distinction is important because a related family member can share a package while differing in configuration, ordering grade, or exposed functionality. Confirm pin availability, LED drive limits, EEPROM interface requirements, and startup defaults before assigning indicator or configuration circuits. A staged bring-up plan should check power rails, reset behavior, USB enumeration, and indicator states before finalizing the enclosure and connector design.
Recommandé
USB Test and Measurement Fixture
A USB 2.0 hub controller can be useful in test fixtures that combine a host computer with multiple low-power measurement or programming peripherals. The CY7C65620-56LFXA is identified as a low-power controller in a 56-QFN package, but the supplied material does not specify measurement-mode timing, isolation, or port-current limits. Those omissions are significant for fixtures because attached instruments may draw more current than a general-purpose peripheral. Use the official electrical limits to design protection, power switching, and cable routing. A practical fixture should include accessible test points, controlled USB power, robust return paths, and protection against accidental cable or peripheral faults. Validate enumeration and data integrity with the intended host operating system before production.

Notes de conception
Begin the PCB layout by checking the official CY7C65620 package drawing and pin table before assigning the 56-QFN footprint. Keep USB differential pairs short, tightly coupled, and routed over a continuous ground reference. Because the supplied data does not specify trace impedance, pair spacing, connector geometry, or maximum cable length, do not invent values; use the manufacturer’s USB layout recommendations and validate the final stack-up with the actual board materials.
Design the USB power tree only after obtaining the target device’s electrical limits from the manufacturer datasheet. The supplied excerpts identify a low-power USB 2.0 hub controller but provide no operating voltage, port-current limit, quiescent current, or power-dissipation values. Verify the voltage regulator headroom, downstream-port current budget, inrush behavior, and protection strategy so that the controller is not asked to supply power beyond its documented limits.
Do not substitute CY7C65620-56LTXC, CY7C65620-56LTXA, or another CY7C65630 variant solely because the package is identified as 56-QFN. Related ordering codes can differ in pin function, configuration, temperature grade, or USB behavior. Compare the exact ordering tables, pin names, exposed-pad connections, electrical limits, and lifecycle status. Also verify whether the target requires firmware, an EEPROM, or particular GPIO strap settings before PCB release.
Treat USB data routing as a controlled-impedance signal-integrity problem rather than a generic digital interface. Keep connector-to-controller routes as direct as practical, minimize stubs and test pads, separate from switching-node and high-current paths, and maintain uninterrupted return-current continuity. The verified excerpts do not provide rise-time, impedance, or timing targets, so use the official datasheet and connector specifications for compliance testing with the intended USB 2.0 host and cable lengths.
Informations de conformité
The supplied verified data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Compliance claims require confirmation from the manufacturer’s current product documentation.
