CY7C65630-56LTXC - 4-Port USB 2.0 Hub Controller | Infineon
MPN: CY7C65630-56LTXC ✓ ActiveCY7C65630-56LTXC Overview
A USB hub controller is an interface-controller semiconductor that manages traffic between one upstream USB host and multiple downstream USB devices. The CY7C65630 belongs to the EZ-USB HX2LP low-power hub-controller family and provides the transaction-translation, port-management, and configuration functions needed to implement a four-port USB 2.0 hub. A single-translator architecture consolidates upstream traffic handling while configurable GPIOs support status indicators and peripheral functions.
Key verified features include support for as many as four downstream ports, USB 2.0 specification compliance, Full Speed and High Speed operation, and compatibility with both bus-powered and self-powered devices. The controller is configurable through GPIOs, supports LED indication, and can use an EEPROM for configuration storage. The verified source data also identifies USB-IF certification under TID 30000009 and Windows Hardware Quality Lab compliance.
The device provides a USB interface specifically designed for hub implementation, with dedicated support for downstream port management and configurable status behavior. Its 3.3 V operating supply is suitable for conventional USB controller electronics, while the C-grade designation identifies the manufacturer’s commercial temperature grade. The provided web results describe availability for automotive and industrial-grade options up to 85 °C, but the exact operating-temperature range of this specific orderable MPN is not stated.
Typical uses include four-port USB hubs, USB connection points in industrial equipment, peripheral docking systems, and embedded host platforms that require more than one USB port. Configuration GPIOs can be assigned to hub activity indicators or other system functions, while EEPROM support can simplify port-specific initialization. In a self-powered design, the hub supply must provide the power required by connected downstream devices rather than relying entirely on upstream bus current.
Designers should verify the exact pin assignments, power requirements, crystal or clocking requirements, port-routing options, and exposed-pad connection against the manufacturer datasheet before layout. The saw-type QFN construction requires careful assembly-process compatibility checks and adequate thermal-via implementation beneath the exposed pad where applicable. Production designs should also confirm USB-IF certification requirements and the exact operating-temperature grade for the intended deployment.
This product record combines the official Infineon device description with distributor and cross-reference evidence. It distinguishes verified hub capabilities from unavailable electrical details, identifies the documented relationship to the CY7C65630-56LFXC, and provides design-oriented guidance for USB hub implementation without inventing unverified pin assignments or prices.

Typical Applications
CY7C65630-56LTXC is suitable for 6 applications: Four-Port USB 2.0 Hub, Industrial USB Connection Hub, Embedded USB Expansion, USB Docking Station, USB Test and Measurement Hub, USB-to-Ethernet Adapter.
Four-Port USB 2.0 Hub
The CY7C65630-56LTXC is designed for a four-port USB 2.0 hub because it supports as many as four downstream ports through one transaction translator. The 3.3 V controller can operate in bus-powered or self-powered hub arrangements, giving the board designer flexibility around available upstream power. Configurable GPIOs can drive connection or activity indicators, while EEPROM support can provide nonvolatile configuration storage. In a self-powered implementation, the supply must cover downstream-device demand rather than relying solely on current advertised by the upstream host. The 56-pin QFN also keeps the hub controller footprint compact enough for compact desktop, industrial, and embedded peripheral designs.
Recommended
Industrial USB Connection Hub
The CY7C65630-56LTXC fits industrial USB connection hubs that require one upstream connection and multiple downstream device ports. Its single-translator USB 2.0 architecture consolidates host traffic while configurable GPIOs permit connection-status or fault indication on the enclosure. The 3.3 V operating supply integrates naturally with industrial controller electronics, and the verified source describes automotive and industrial-grade options in the broader family, with variants reaching 85 °C. Because the exact temperature limits of this MPN are not published in the supplied excerpts, industrial designers must confirm the orderable grade against their enclosure temperature and worst-case operating requirements.
Recommended
Embedded USB Expansion
The CY7C65630-56LTXC can add four USB 2.0 downstream ports to an embedded controller platform that otherwise exposes only a single host connection. Its GPIO configurability allows the four ports to be associated with application-specific status LEDs or control signals, while the single-translator arrangement reduces the number of high-speed routing resources needed for hub management. The 56-pin QFN package is appropriate for compact embedded equipment, but the exposed-pad construction requires assembly and thermal planning. Before schematic capture, engineers should obtain the official pin table to confirm USB data routing, supply requirements, clocking, and grounds.
Recommended
USB Docking Station
A docking station can use the CY7C65630-56LTXC to provide four USB 2.0 ports behind one upstream connection to a host computer. The controller supports Full Speed and High Speed devices, bus-powered and self-powered configurations, LED indicators, and EEPROM-based setup, making it suitable for mixed peripheral loads. In a self-powered dock, the power supply must support the worst-case sum of downstream currents rather than only the controller’s own operating current. The four-port architecture simplifies enclosure wiring and user access while keeping the controller in a compact 8 mm by 8 mm QFN package.
Recommended
USB Test and Measurement Hub
The CY7C65630-56LTXC can organize several USB-connected instruments or service tools behind a single upstream USB 2.0 link. Its configurable GPIOs are useful for assigning port LEDs or interlock indicators, and EEPROM support can retain configuration information. Full Speed and High Speed support allows both low-speed peripherals and high-bandwidth devices to share the hub within the limits of USB 2.0. For laboratory equipment, self-powered operation is generally preferable when attached devices draw substantial current. Designers should verify signal integrity, connector protection, grounding, and the exact port-routing options in the manufacturer datasheet before release.
Recommended
USB-to-Ethernet Adapter
The CY7C65630-56LTXC can provide upstream USB connectivity for an adapter that also incorporates Ethernet or another communications function. A four-port hub implementation lets one USB host connection reach multiple internal peripheral functions, while configurable GPIOs can report link or fault states through LEDs. The controller’s 3.3 V operation and USB 2.0 Full Speed and High Speed support suit data adapters, provided the Ethernet interface and magnetics are designed separately. The 56-QFN footprint helps limit board area, but exposed-pad soldering, thermal vias, and USB connector routing remain critical to reliable implementation.

Key Differentiators
- Documented functional replacement relationship (vs CY7C65630-56LFXC)
- Four-port single-translator hub architecture (vs CY7C65631-56LTXC)
- Configuration flexibility for peripheral hubs (vs CY7C65630-56LFXC)
Design Notes
Place the USB high-speed differential pairs as short and impedance-controlled as the manufacturer layout guidance specifies. The QFN footprint requires correct pad geometry, exposed-pad soldering, and thermal-via placement; these assembly details can materially affect both yield and signal integrity. Confirm the land pattern and pad numbering against the official package drawing before releasing artwork, particularly when transferring from the punch-singulated LFXC to the saw-singulated LTXC.
Determine whether the finished hub must source downstream power from the USB host or use a self-powered supply. The controller supports both modes, but the external power path determines how much current can safely be delivered to attached devices. For a self-powered hub, size the supply for the worst-case downstream demand, implement appropriate protection, and ensure the controller supply remains within its specified operating range.
Do not infer the CY7C65631-56LTXC pin compatibility from its shared 56-QFN package alone. The supplied comparison result does not identify the changed feature or quantify its electrical effect. Compare the official pin tables and functional descriptions, especially for GPIO assignment, clocking, EEPROM behavior, port routing, and exposed-pad requirements, before treating it as a drop-in substitution.
The CY7C65630-56LTXC uses a 56-pin QFN with an exposed thermal feature rather than a leaded package. Use the manufacturer’s recommended pad and via layout to lower junction temperature and avoid assembly voids. Because verified junction-to-ambient resistance, maximum dissipation, and exact die/thermal data were not supplied, they should not be estimated for production thermal qualification without the manufacturer datasheet.
Compliance Information
The verified excerpts identify USB-IF certification under TID 30000009 and Windows Hardware Quality Lab compliance. They do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status, so those fields remain unknown.
