CY7C65630-56LFXAT Low-Power USB 2.0 Hub Controller
N.º da peça: CY7C65630-56LFXAT ✗ Fim de vidaCY7C65630-56LFXAT Visão geral
A USB hub controller is an interface IC that manages USB connectivity between a host and one or more downstream ports. In the system hierarchy, it sits between the USB host controller and USB peripherals, combining USB interface logic, port-management functions, and low-power hardware characteristics. The CY7C65630 is therefore a USB interface IC rather than a general-purpose microcontroller, although it can be paired with a host processor for configuration and firmware control.
The CY7C65630 family is identified as an EZ-USB HX2LP low-power USB 2.0 hub controller. The verified manufacturer datasheet identifies the USB 2.0 hub controller family and the integrated pull-up, pull-down, and series termination components. These features reduce the number of external USB signal-conditioning components required in a hub design and support direct connection of the USB data lines according to the device implementation requirements.
The target ordering code uses a 56-QFN package, also described in the verified distributor information as an 8 mm x 8 mm QFN package. The package is lead-free according to the distributor listing, and the device is categorized as a CMOS USB bus controller. The exact electrical ratings, operating-temperature limits, GPIO assignments, clock requirements, and USB transceiver details should be confirmed against the manufacturer datasheet before final PCB release.
Typical applications include USB 2.0 hubs, multi-port USB expansion equipment, USB connection to external storage, USB peripherals, and embedded USB systems requiring multiple downstream ports. The integrated termination and bias resistors are particularly useful in compact designs where component count and routing simplicity matter. A host processor can manage enumeration and higher-level device configuration while the hub controller handles the physical USB interface and port-management functions.
The principal design consideration is ensuring that the PCB land pattern, power distribution, USB data routing, and external component selection follow the manufacturer reference layout. USB differential pairs should be routed with controlled impedance and minimized discontinuity, while power and ground connections should provide low-impedance return paths. This page combines the manufacturer datasheet, distributor package information, and practical guidance for evaluating the CY7C65630-56LFXAT in a USB hub design.

Aplicações típicas
CY7C65630-56LFXAT é adequado para 6 aplicaçãos: Compact Four-Port USB 2.0 Hub, USB Storage Expansion Dock, Embedded USB Peripheral Hub, Industrial USB Data Acquisition Hub, USB-to-Serial Multiport Adapter, USB Connectivity Test Fixture.
Compact Four-Port USB 2.0 Hub
The CY7C65630-56LFXAT is well suited to a compact four-port USB 2.0 hub because it combines one upstream connection with four downstream hub ports in the EZ-USB HX2LP family. Its integrated 1.5 kΩ upstream pull-up resistors, 15 kΩ downstream pull-down resistors, and series termination on the D+ and D- lines can reduce the number of external USB conditioning components. The 56-QFN 8 mm x 8 mm package also supports compact routing, although the PCB must follow the manufacturer land pattern and reference layout. Firmware and host-side enumeration support should be evaluated with the implementation team before production release.
Recomendado
USB Storage Expansion Dock
The CY7C65630-56LFXAT can support a USB storage expansion dock where one upstream USB 2.0 connection fans out to multiple downstream peripherals. Its low-power USB 2.0 hub-controller positioning is appropriate for coordinating external drives, card readers, and input devices, while the integrated USB biasing and termination resistors simplify the high-speed signal network. Four downstream ports provide useful expansion without requiring four unrelated host connections. The implementation must still validate connector overcurrent behavior, cable routing, ground continuity, and power-supply capacity for the combined downstream load.
Recomendado
Embedded USB Peripheral Hub
For an embedded system that accepts several USB peripherals through one host port, the CY7C65630-56LFXAT provides a dedicated four-port USB 2.0 hub interface. The EZ-USB HX2LP integration reduces the discrete-component count associated with USB biasing and series termination, which can benefit a compact embedded enclosure. The controller should be paired with the appropriate host processor and device firmware to manage enumeration, connection status, and downstream power policy. PCB placement must prioritize short, impedance-controlled differential routes and a continuous ground reference beneath each USB data pair.
Recomendado
Industrial USB Data Acquisition Hub
The CY7C65630-56LFXAT is applicable to an industrial data-acquisition enclosure that connects several USB instruments to one host interface. Its four downstream ports allow measurement devices, service interfaces, and configuration adapters to share a controlled USB 2.0 connection. The integrated pull-up, pull-down, and series termination features simplify the USB physical layer, but reliability still depends on careful connector design, cable-length budgeting, and separation from high-current or noisy power paths. Industrial qualification requirements, including temperature grade and EMC validation, must be confirmed for the exact ordering suffix and finished assembly.
Recomendado
USB-to-Serial Multiport Adapter
A USB-to-serial adapter can use the CY7C65630-56LFXAT when several downstream serial or legacy peripheral interfaces are converted through USB. One upstream USB 2.0 link provides the host-facing connection, while four downstream ports support multiple device branches when the attached adapters use compatible USB interfaces. The controller's integrated termination and bias resistors help standardize each branch, while downstream power switching and overcurrent protection remain board-level design responsibilities. Validate all converter signal levels and ensure that branch capacitance does not degrade USB signal integrity.
Recomendado
USB Connectivity Test Fixture
The CY7C65630-56LFXAT can serve as the hub element in a USB connectivity test fixture designed to expose multiple downstream ports to a host controller. Four downstream branches make it possible to characterize plug-and-unplug behavior, power states, enumeration, and signal integrity across several connections. The integrated USB bias and termination components reduce fixture complexity, while the compact 56-QFN package leaves board area for test points and instrumentation. Use controlled-length cables, maintain defined power limits, and provide independent observability for each port so failures can be attributed to the target device or peripheral.

Notas de projeto
Route every USB D+ and D- pair as a controlled-impedance differential pair over a continuous ground reference. Keep the pairs short, avoid stubs and test pads where practical, and match upstream and downstream branch geometry as closely as the layout allows. Place connector protection and common-mode components at the connector boundary, while keeping the CY7C65630-56LFXAT and its decoupling network close to the associated data pins.
Use the manufacturer package drawing and reference layout for the 56-QFN 8 mm x 8 mm footprint. Confirm exposed-pad requirements, solder-mask clearance, and the number of ground connections before releasing Gerber files. Place input and output decoupling capacitors adjacent to their supply pins and provide a low-impedance ground return under the device to minimize inductance on high-frequency switching current.
The controller's integrated USB pull-up and pull-down resistors do not replace system power planning. Calculate downstream port current, inrush, and shared supply dissipation before selecting external power switches. Add adequate bulk capacitance near each power source and validate the hot-plug voltage excursions with the actual cable, connector, and peripheral load rather than relying only on nominal device ratings.
Do not substitute a family name such as CY7C65630 for the full ordering code when approving a purchase or footprint change. Suffixes can encode package, temperature grade, qualification, or packing options. Compare the complete manufacturer ordering table for the target and proposed part, then confirm lead time and lifecycle status through the Request a Quote form before making a production commitment.
