CY7C65630-56LTXA - USB 2.0 Hub Controller | Infineon
MPN: CY7C65630-56LTXA ✓ ActiveCY7C65630-56LTXA Overview
A USB hub controller is a bus-interface integrated circuit that coordinates communication between one upstream USB host and multiple downstream ports. It sits within the broader hierarchy of interface controller, USB interface IC, USB hub controller, and semiconductor. Unlike a general-purpose microcontroller, the dedicated hub controller incorporates USB host and device interface functions specifically organized for hub topologies. Its exact port count, transfer rates, clocking requirements, and supported operating modes should be confirmed against the manufacturer datasheet before schematic capture.
The CY7C65630-56LTXA is identified in distributor listings as a USB 2.0 USB Interface controller. The verified product listings place it in the Bus Controllers and Interface Controllers classes, supporting use in hubs, docking stations, card readers, embedded USB expansion systems, and industrial peripherals. The compact 8 mm by 8 mm QFN package is useful where connector density and board area constrain the design.
Thermal and layout planning are especially important for this no-lead package. The exposed ground structure must be connected to a low-impedance ground plane, while supply and interface routing should follow the reference layout and decoupling guidance in the manufacturer documentation. Because the supplied data does not state the complete electrical limits, verify input voltage tolerance, maximum downstream-port current, operating temperature range, and signal timing before committing to a production layout.
The CY7C65630-56LTXA is available from multiple authorized distributors, with DigiKey and Mouser listings present at the time of verification. Quote-based procurement can be appropriate when stock and lead time fluctuate. The family also includes related 56-QFN ordering variants, but suffix changes can indicate package construction or grade differences rather than unconditional functional interchangeability.
This page consolidates distributor availability, package information, related same-family MPNs, and practical integration considerations. It also distinguishes verified facts from engineering values that still require confirmation from the official datasheet, preventing package-only substitutions from being presented as automatic drop-in replacements.

Typical Applications
CY7C65630-56LTXA is suitable for 6 applications: Compact USB 2.0 Hub, Docking Station Connectivity, Industrial USB Expansion, USB Card Reader, Embedded USB Expansion Board, Test and Measurement Peripheral Hub.
Compact USB 2.0 Hub
The CY7C65630-56LTXA is suited to the hub-controller position in a compact USB 2.0 expansion product because the verified listings identify it specifically as a USB 2.0 hub and bus controller. Its 56-QFN package measures only 8 mm by 8 mm, allowing the controller to sit close to downstream connector and routing infrastructure. A practical layout should follow the manufacturer reference layout, connect the exposed ground region to a solid plane, and keep high-current switching nodes away from data pairs. The verified snippets do not specify downstream-port count or available port current, so those limits must be confirmed before assigning connectors or calculating hub power.
Docking Station Connectivity
In a docking station, the CY7C65630-56LTXA can provide the dedicated USB interface logic needed to organize several external connections around one upstream host link. The 56-terminal QFN footprint is suitable for space-constrained dock electronics, where connector placement frequently competes with controller area. Use the official pinout to place ESD protection close to connectors and maintain the specified USB trace geometry. Because the supplied data does not verify the number of downstream ports, operating temperature, or total bus current, a docking-station architecture must treat those values as unresolved design inputs rather than assumed hub capabilities.
Industrial USB Expansion
The CY7C65630-56LTXA can serve as the USB hub controller in industrial equipment that expands one host connection into multiple service or peripheral ports. Its dedicated USB 2.0 bus-controller role separates that task from the host processor, and the compact 8 mm by 8 mm QFN package leaves routing space for protection and power components. Industrial adoption should be conditioned on verification of the operating-temperature limits, supply tolerance, and lifecycle status in the official documentation. Short connector leads, chassis grounding, and common-mode filtering also matter more than nominal hub-controller speed in electrically noisy industrial cabinets.
USB Card Reader
The CY7C65630-56LTXA can contribute USB hub functionality to a multi-format card reader or removable-media dock that connects storage adapters through a single upstream USB port. A dedicated controller simplifies the USB device topology compared with assigning all port management to a general-purpose microcontroller. Place the controller close to the USB connector region, provide local decoupling as specified by the manufacturer, and use short matched USB traces for the downstream links. The verified source only establishes the controller class and package, so storage-card support, advertised USB speeds, and power-current limits must be confirmed against the actual datasheet before release.
Embedded USB Expansion Board
The CY7C65630-56LTXA is a candidate for an embedded USB expansion board that adds downstream connectivity to a set-top box, industrial controller, or media appliance. Its small square no-lead package allows placement on both sides of a dense PCB, although assembly yield and the exposed-pad connection require attention. The board should provide continuous ground reference beneath the package, per the manufacturer layout, and avoid routing USB differential pairs beneath noisy power-converter areas. Because the supplied evidence does not establish programming interface, register behavior, or port count, firmware reuse is only appropriate after the two devices are compared in detail.
Test and Measurement Peripheral Hub
The CY7C65630-56LTXA can be evaluated for laboratory and test peripherals that need several USB connections managed by a dedicated hub controller. Its USB 2.0 classification and compact 56-QFN package make it relevant to portable analyzers and desktop interface adapters. Reliable measurement performance depends on clean supply rails, short connector-to-PCB routes, and controlled return paths, while USB enumeration and device-power stability must be tested with the final accessory mix. The verified material does not state operating voltage, maximum current, or temperature limits, so these are gating checks for laboratory and production deployment.

- Active distributor-channel coverage (vs CY7C65630-56LFXA)
Design Notes
Treat the manufacturer package drawing and reference layout as the authority for this 56-QFN device. The verified records confirm an 8 mm by 8 mm square no-lead package but do not expose the individual pin map, so do not reconstruct the footprint solely from the terminal count. Keep the exposed thermal and ground structure tied to a low-impedance plane, route high-speed differential pairs without stubs, and place interface protection close to external connectors rather than beside the controller.
Calculate the hub power budget from the actual downstream-port configuration, attached-device current, inrush behavior, and the controller's verified supply current. None of those electrical values is available in the supplied snippets. Consequently, the 0.00 tier values represent quote-on-request rather than a zero-cost device. Validate the power supply under worst-case enumeration and overcurrent conditions so the controller is not operated beyond its verified limits.
Do not assume that parts sharing the CY7C65630 family name and 56-terminal package are automatically interchangeable. The verified listing for CY7C65630-56LTXC mentions sawn-type construction and C-grade construction, showing that suffix details can carry orderable or qualification meaning. Before substitution, compare the pinout, exposed-pad connection, electrical limits, supported topology, and package-construction notes in the official ordering information and datasheet.
Route USB data connections as controlled-impedance differential pairs with continuous reference planes and minimize vias and stub branches. Place any external protection close to the connector and keep its return connection into the ground system. Use the manufacturer's recommended layer stack and trace geometry where available; generic USB guidance cannot replace the exact pin placement, clock topology, and bypass requirements of this controller.
Compliance Information
The supplied verified data identifies the manufacturer, USB interface class, package, dimensions, and terminal count but does not state the substance-compliance or automotive-qualification status. No compliance claim has been inferred from the orderable suffix.
