CY7C65630-56LFXCT - 4-Port USB 2.0 Hub Controller | Infineon
Référence : CY7C65630-56LFXCT ✓ ActifCY7C65630-56LFXCT Présentation
A USB hub controller is an interface IC that manages traffic between one upstream USB host connection and multiple downstream USB ports. It coordinates enumeration, packet routing, power management, and device attachment across the hub. The CY7C65630 family integrates 1.5 kΩ upstream pull-up resistors for full-speed operation, 15 kΩ downstream pull-down resistors, and series termination resistors on upstream and downstream D+ and D- signals.
The CY7C65630-56LFXCT provides four downstream USB 2.0 hub ports through configurable GPIO resources. Its configuration supports port indicators and EEPROM-based setup, while the integrated bus resistors help reduce external component count. The low-power architecture is intended for compact USB 2.0 systems where board area and component count are important. The 56-QFN package also supports compact surface-mount construction in docking and embedded USB equipment.
The 56LFXCT ordering code identifies a 56-pin QFN package. Infineon lists the related CY7C65630-56LTXC as a 4-port, single-TT hub with configurable GPIOs, LED indicators, EEPROM support, and a 56-pin QFN package. The related LFXC-to-LTXC change is attributed by Infineon to package singulation, with the sawn-type package supporting a more reliable supply source.
For implementation, treat D+ and D- routing as a controlled-impedance USB task. Keep upstream and downstream differential pairs routed as short, continuous pairs away from switching nodes and noisy clocks. Follow the manufacturer’s recommended capacitor placement and provide the downstream-port overcurrent and power-distribution arrangements required by the target USB design.
This page combines manufacturer-family details, package information, ordering-code distinctions, replacement guidance, and practical USB hub design considerations. It also identifies the limits of the available substitution information so engineers can distinguish documented same-family replacements from parts that would require independent pin and firmware validation.

Applications typiques
CY7C65630-56LFXCT convient pour 6 applications: Four-Port USB 2.0 Hub, USB Docking Station, Kiosk and Self-Service Terminal, Printer and Media Hub, Embedded Measurement and Control Hub, USB-to-Serial Bridge Product.
Four-Port USB 2.0 Hub
The CY7C65630-56LFXCT fits a compact four-port USB 2.0 hub that connects one host-facing upstream port to four downstream peripherals. Its single-transaction-translator architecture supports hub traffic management, while the integrated 1.5 kΩ upstream pull-up, 15 kΩ downstream pull-down resistors, and series termination reduce the external USB data-resistor network. The 8 mm by 8 mm 56-QFN package also conserves board area compared with many discrete hub implementations. Designers still need to implement downstream power switching, overcurrent protection, connector routing, and firmware appropriate for the supported device set.
Recommandé
USB Docking Station
A docking station can use the CY7C65630-56LFXCT to provide one upstream USB connection to a host and four downstream ports for peripherals such as keyboards, storage, networking, and human-interface devices. The controller’s configurable GPIOs, LED-indicator capability, and EEPROM support help implement port-status reporting and configuration retention. Its integrated USB termination resistors reduce board-level component count, while the compact QFN package suits densely populated docks. Board planning must preserve USB signal integrity and implement the required port-current protection separately from the hub controller.
Recommandé
Kiosk and Self-Service Terminal
The CY7C65630-56LFXCT is appropriate for kiosks and self-service terminals that expose several USB peripherals through a single host connection. A four-port configuration can support service devices such as card readers, printers, scanners, or authentication hardware without distributing host-controller resources directly to each peripheral. Configurable GPIO and LED support allow the enclosure to indicate enumeration or port activity. Since kiosk power requirements can vary widely, validate each downstream port against the system power budget and place protection and switching components where needed.
Recommandé
Printer and Media Hub
The CY7C65630-56LFXCT can manage USB 2.0 peripherals in an embedded printer, media-access terminal, or multifunction peripheral. Four downstream ports provide room for a print engine interface, status display, card reader, or local storage device while preserving one upstream link to the host or embedded controller. The low-power HX2LP family and integrated bus resistors are useful in compact embedded products. Firmware must match the actual device types, and the USB power architecture must remain independent from signal-routing decisions.
Recommandé
Embedded Measurement and Control Hub
Test, measurement, and industrial-control equipment can use the CY7C65630-56LFXCT to consolidate several USB 2.0 service interfaces behind one upstream connection. The four downstream ports may serve calibration equipment, data loggers, diagnostic adapters, or configuration interfaces. Configurable GPIO and EEPROM functions support hardware-specific behavior and retained settings. Because measurement systems can combine sensitive analog circuitry with USB traffic, route D+ and D- away from noisy analog paths and use the integrated termination network exactly as specified in the manufacturer application guidance.
Recommandé
USB-to-Serial Bridge Product
The CY7C65630-56LFXCT can serve as the upstream USB hub function in a multi-interface bridge product that also exposes serial, network, or control interfaces. A single upstream USB path can connect the embedded hub function to a host, while separate downstream ports remain available for service adapters or external devices. The same-page alternatives include RS-232 and RS-485 interface devices that demonstrate how hub control can coexist with other communications functions. Final compliance depends on the complete product architecture, not the hub controller alone.

Notes de conception
Route the upstream and all downstream USB D+ and D- nets as short, continuous differential pairs with consistent geometry. Avoid stubs, test pads that interrupt the pairs, and long coupling paths between adjacent channels. Place the controller and required USB capacitors close to their associated pins, and keep switching-regulator traces and high-current power paths away from the data pairs. These controls are particularly important because the controller integrates pull-up, pull-down, and series-termination components for a complete USB data network.
Do not substitute the CY7C65630-56LFXCT solely because a candidate has a 56-QFN outline. Infineon documents the LFXC-to-LTXC change as a package-singulation transition from punch to saw processing. Confirm exposed-pad geometry, solderable land pattern, pin numbering, thermal requirements, and the manufacturer’s package drawing before substituting. For CY7C65631-56LTXCT, additionally verify GPIO allocation, EEPROM behavior, and firmware because the available information supports family and package proximity but does not establish feature-for-feature equivalence.
Treat USB downstream power as a separate design layer from the controller’s signal network. Determine each port’s required current, specify downstream power switches and overcurrent protection according to the target USB design, and calculate total power demand before selecting supply components. The controller’s integrated bus resistors do not replace external port-power protection. Keep thermal dissipation from power switches and regulators away from sensitive USB routing, and verify that each connector’s current rating supports the intended peripheral load.
Use the manufacturer’s recommended capacitor network and placement for both upstream and downstream USB ports. Place input and output capacitors adjacent to their associated controller pins using the shortest practical ground paths, while observing the datasheet’s capacitor type, voltage rating, and tolerance requirements. Keep the QFN exposed pad solder process compatible with the selected package variant and verify the land pattern for punch-singulated versus sawn-singulated production options before releasing artwork.
Informations de conformité
The available product records do not explicitly state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification status for the exact CY7C65630-56LFXCT ordering code. AEC-Q100 is treated as not applicable because this is a USB hub interface controller rather than an automotive-qualified device family, and the record does not claim automotive qualification.
