CY7C65642-48AXC - 4-Port USB 2.0 Hub Controller | Infineon
MPN: CY7C65642-48AXC ✗ Cuối đờiCY7C65642-48AXC Tóm tắt
A USB hub controller is an interface IC that manages traffic between one upstream USB host connection and multiple downstream USB ports. Within the product hierarchy, this device is a USB interface controller, then a USB hub controller, then a USB 2.0 peripheral. Its HX2VL architecture is intended to isolate traffic and improve low-cost multi-port USB designs while minimizing external bill-of-material requirements.
Verified product information identifies support for both full-speed and high-speed USB operation, two or four configurable ports, LED indicators, and EEPROM-based configuration. The four-port configuration uses GPIO options for port behavior and status indication. A 3.3 V or 5 V system design is possible within the verified 3.15 V to 5.25 V range, but individual downstream-port current limits, crystal requirements, signal-routing rules, and exact transceiver timing must be taken directly from the manufacturer datasheet.
The CY7C65642 belongs to the HX2VL family, whose four-downstream-port option is optimized for low-power, high-performance USB hubs. Its 48-pin TQFP package is larger than the family's 28-pin QFN option, but the verified listing specifically identifies the 7 mm × 7 mm 48-TQFP configuration. The part is marked not recommended for new designs, and an Infineon community response identifies CY7C65630 and CY7C65631 as active alternatives for four-port designs; however, those candidates require package and pin-level review before being treated as replacements.
Typical applications include four-port USB hubs, desktop and laptop docking products, printers, storage peripherals, industrial USB interfaces, and embedded USB expansion systems. In each case, the controller handles port enumeration and transaction translation while external power-switching, connector, clock, and passive components complete the system.
PCB implementation should preserve the USB data-pair geometry specified by the manufacturer, place bypass capacitance near the supply pins, and account for the 100 mA device operating current separately from downstream-port loading. Because the lifecycle is NRND and verified drop-in replacements are limited, new USB hub designs should confirm firmware, firmware-independent configuration, pin compatibility, and supply requirements with Infineon before layout release.

Ứng dụng tiêu biểu
CY7C65642-48AXC phù hợp cho 6 Áp dụngs: Four-Port External USB Hub, USB Docking Station, Printer and Storage USB Hub, Industrial USB Interface Box, USB-to-Multiport Peripheral Hub, Legacy USB Expansion Retrofit.
Four-Port External USB Hub
CY7C65642-48AXC is well matched to an external four-port USB 2.0 hub because it provides four downstream ports and an independent transaction translator for each port. The controller is designed for low-power, low-cost hub implementations and operates from 3.15 V to 5.25 V, allowing integration with a compatible hub power architecture. The design must include the required USB connectors, transceiver routing, clock support, configuration EEPROM, port-power controls, and bypass components. The verified 100 mA operating-current figure describes the controller operating condition, not the total downstream load, so each port's power budget must be calculated separately.
Được đề xuất
USB Docking Station
A docking station can use CY7C65642-48AXC when one upstream USB connection must fan out to several downstream peripherals. Its four configurable ports support a product architecture that includes storage, input, or communications peripherals without placing multiple independent host controllers on the board. The 48-pin TQFP footprint provides adequate routing space for USB differential pairs compared with smaller packages. Designers should preserve the manufacturer's recommended impedance-controlled USB traces, keep clock and power distribution clean, and provide ESD protection at every externally accessible connector.
Được đề xuất
Printer and Storage USB Hub
CY7C65642-48AXC is appropriate for a shared USB hub connected to a printer, storage device, keyboard, or other peripherals. Its four-port HX2VL architecture separates downstream transactions, which can help isolate traffic among devices in a low-cost hub design. The controller's 28 µA low-power current is relevant to power-conscious peripheral designs, but total system consumption depends on the number of active ports, downstream devices, and the selected power switches. Validate enumeration behavior, cable-length margins, connector protection, and power-switching delays in the final hardware.
Được đề xuất
Industrial USB Interface Box
CY7C65642-48AXC can serve as the USB interface engine in an industrial USB interface box that exposes several peripherals to a host computer. Its 0 °C to +70 °C commercial temperature specification is suitable for ordinary indoor equipment, but it does not cover extended-temperature industrial environments. The verified 3.15 V to 5.25 V operating range supports integration with both 3.3 V and 5 V supply domains when all other interface requirements are satisfied. Use ESD protection, robust connector design, controlled grounding, and verified power-budget margins for field-facing equipment.
Được đề xuất
USB-to-Multiport Peripheral Hub
For an embedded peripheral that exposes multiple USB connections, CY7C65642-48AXC provides a consolidated USB hub-controller solution rather than requiring separate downstream routing logic in the host processor. GPIO configurability, LED indication, and EEPROM support allow product-specific port behavior and configuration in a compact controller design. The system designer must confirm whether the intended downstream devices require full-speed or high-speed operation, whether bus-powered or self-powered behavior is required, and whether the available USB connector and protection scheme meet the target compliance goals.
Được đề xuất
Legacy USB Expansion Retrofit
CY7C65642-48AXC can be considered for a maintenance or retrofit design that needs to retain an existing four-port USB hub architecture. Since the device is NRND, its strongest use case is preserving proven connectivity rather than starting a new platform without lifecycle review. Confirm that the original board uses the 48-pin TQFP pinout, that its EEPROM contents and configuration behavior are understood, and that downstream power and USB routing match the original design. For new production, an active controller should be preferred after a complete pin and firmware compatibility review.

Ghi chú thiết kế
Treat USB routing as a high-speed signal-integrity constraint even though the target also supports full-speed operation. Route each USB differential pair with the impedance and pair geometry required by the manufacturer datasheet, minimize stubs and layer transitions, and place ESD protection close to the external connector. Do not use the distributor snippets as a substitute for the complete reference layout, especially when designing a four-port hub with long downstream traces.
Separate the controller's 100 mA operating-current specification from the current required by downstream USB devices and port-power switches. Calculate the complete 3.15 V to 5.25 V supply budget under worst-case port activity, verify regulator headroom at the selected 3.3 V or 5 V rail, and place local bypass capacitors at the controller supply pins. The 28 µA figure describes a low-power condition and should not be used as the total system power budget.
The verified cross-reference material names CY7C65630 and CY7C65631 as active four-port alternatives, but it does not prove identical pinouts or package dimensions. Before substituting either part, compare the complete pin list, supply requirements, clock implementation, EEPROM interface, GPIO assignments, USB transceiver connections, and package drawings. Do not treat a same-port-count recommendation as proof of drop-in replacement.
Preserve the manufacturer's recommended clock and configuration layout, keeping sensitive timing and USB-routing regions away from noisy switching converters and high-current power paths. Confirm the role of every GPIO and LED connection because the product supports configurable hub functions. For tray versus tape-and-reel ordering, the electrical design is unchanged, but the assembly process and incoming-reel handling must match the selected package ordering code.
