CY7C65634-48AXC - USB 2.0 Hub Controller | Infineon
MPN: CY7C65634-48AXC ✓ AktifCY7C65634-48AXC Genel Bakış
A USB hub controller is an interface IC within the USB interface-controller and USB connectivity hierarchy. It manages traffic between an upstream USB host and downstream USB ports, while coordinating enumeration, connection, suspend, resume, and port-status functions. The CY7C65634-48AXC is positioned for USB 2.0 hub applications, including peripheral expanders, embedded USB equipment, and multi-port connectivity products.
The manufacturer identifies the device as the EZ-USBTM HX2VL USB 2.0 hub controller and specifies a two-port single-TT configuration. The supplied component data identifies a 3.3 V supply, 0 °C to 70 °C operating range, and a 48-pin TQFP package. The verified distributor listing additionally identifies USB 2.0 high-speed hub functionality and USB interface classification. Detailed electrical limits, GPIO mappings, crystal requirements, and timing parameters remain dependent on the manufacturer datasheet.
The controller is suitable when a board needs more than one USB peripheral connection and must translate between an upstream host connection and downstream ports. Its integrated PLL supports clock-based USB operation, while EEPROM support can assist with configuration storage. GPIO configurability allows the hub implementation to address port indicators and application-specific routing, although the exact supported pin functions must be verified from the device documentation.
Typical design considerations include correct USB trace impedance, short matched routing between controller and connectors, careful handling of upstream and downstream differential pairs, and decoupling of the 3.3 V supply. The 48-pin TQFP package also requires a footprint and land pattern that match the manufacturer’s mechanical drawing; the conflicting package information in third-party listings should not be substituted for the manufacturer package designation.
This page combines the verified manufacturer identity, distributor classification, package information, temperature range, supply voltage, and USB hub positioning with engineering guidance. It does not infer unavailable electrical limits, pricing levels, or replacement parts that are not confirmed by the supplied data.

Tipik Uygulamalar
CY7C65634-48AXC için uygundur 6 uygulamas: Embedded USB 2.0 Hub, USB Peripheral Expansion, Industrial USB Connectivity, USB Test and Measurement, USB-to-Serial Control Adapter, USB Monitoring and Service Fixture.
Embedded USB 2.0 Hub
The CY7C65634-48AXC fits an embedded two-port USB 2.0 hub where a single upstream host connection must fan out to two downstream devices. Its manufacturer-described two-port single-TT configuration provides the core hub topology, while the integrated PLL and 24 MHz external-crystal support in the supplied data address clock implementation. The 3.3 V supply and 48-pin TQFP package make the device appropriate for a compact controller section, subject to confirming the full USB electrical design in the datasheet.
Önerilen
USB Peripheral Expansion
The CY7C65634-48AXC can be used when an embedded system needs to expose two USB downstream connections instead of relying on a single USB peripheral port. The verified manufacturer result identifies the part as a two-port single-TT hub with configurable GPIOs, EEPROM support, and port-indicator control. Those features allow the board designer to coordinate attach, fault, and activity indications, although connector protection, power switching, and exact routing must be engineered around the final USB requirements.
Önerilen
Industrial USB Connectivity
The CY7C65634-48AXC is a candidate for industrial USB connectivity products that need local USB port expansion without relying on a host PC. The verified operating range is 0 °C to 70 °C, so it is appropriate where the enclosure remains within that commercial temperature range. Its integrated PLL, EEPROM support, GPIO configurability, and port indicators support a deterministic hub implementation, but industrial EMC, ESD, surge, and power-fail requirements still need separate validation.
Önerilen
USB Test and Measurement
The CY7C65634-48AXC can be used in a compact USB test or measurement fixture that needs to bring two downstream USB connections to a host or embedded test controller. Its two-port single-TT topology reduces the number of hub functions required in the fixture, while the 48-pin TQFP package provides access to the controller’s digital and configuration signals. For instrumentation, verify signal integrity, port power switching, test-point access, and the 0 °C to 70 °C range before production release.
Önerilen
USB-to-Serial Control Adapter
The CY7C65634-48AXC can serve as the USB hub element in a control adapter that connects a host to multiple programmed or monitored peripherals. The controller’s EEPROM support can assist with configuration storage, and its configurable GPIOs can support port indicators or application-specific control signals. A practical design should keep USB differential routing controlled, provide local decoupling for the 3.3 V rail, and verify power budget and enumeration behavior with the connected USB devices.
Önerilen
USB Monitoring and Service Fixture
The CY7C65634-48AXC is applicable in service fixtures that need multiple USB service connections while preserving a compact controller footprint. The manufacturer-identified port-indicator control can be used to expose attach or fault information, while EEPROM support can retain device or board configuration. Because the supplied data does not include complete timing, ESD, or USB signal-integrity limits, the fixture should be validated against the official datasheet and tested with worst-case cable and connector scenarios.

Tasarım Notları
Use the manufacturer’s 48-pin TQFP mechanical drawing and land pattern rather than the conflicting 56-pin QFN description in one third-party result. Keep USB differential pairs short, symmetric, and continuously referenced to the appropriate plane; route upstream and downstream pairs away from switching nodes and high-current return paths. Confirm the final connector and hub topology against the official datasheet before releasing the PCB.
The verified supply specification is 3.3 V. Place local decoupling close to the controller’s supply pins and provide clean return paths for the USB transceiver and digital sections. Because the supplied data does not include current limits, voltage tolerance, or capacitor values, use the manufacturer datasheet for the final power budget and do not treat LCSC’s component price as an indication of power or performance.
The supplied data contains inconsistent package descriptions: the manufacturer and DigiKey identify a 48-pin TQFP, while one search result associates the MPN with a 56-pin QFN. Do not create a footprint or pinout from that result. Also verify the 24 MHz crystal circuit, PLL configuration, EEPROM connection, and GPIO assignments in the datasheet; catalog-level similarity alone does not establish functional drop-in compatibility.
For an embedded USB hub, place the controller and protection components in an order that minimizes impedance discontinuities between the transceiver pins and connectors. Validate upstream and downstream differential routing with controlled impedance, appropriate via transitions, and return-path continuity. The supplied data identifies USB 2.0 operation but does not provide trace-impedance or timing targets, so those values must be established from the official device and connector documentation.
Uyumluluk Bilgisi
The supplied data does not provide verified RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive-qualification declarations. The 0 °C to 70 °C specification alone does not establish AEC-Q100 qualification.
