CY7C65630-56LFXA - 4-Port USB 2.0 Hub | Infineon
MPN: CY7C65630-56LFXA ✗ پایان تولیدCY7C65630-56LFXA نمای کلی
A USB hub controller is an interface IC within the USB interface controller hierarchy. It manages communication between one upstream USB host connection and multiple downstream peripheral connections. Unlike a simple USB switch, a hub controller coordinates enumeration, port status, power distribution, signaling, and shared-bandwidth behavior. The CY7C65630-56LFXA therefore sits between a USB host or computer and attached USB peripherals in external hubs, docking equipment, and embedded USB connectivity products.
Key features include four downstream USB ports, a single-TT architecture, 3.3 V operation, integrated upstream and downstream termination resistors, and integrated port-status indicator control. The controller uses an external 24 MHz crystal with an integrated PLL, while in-system EEPROM programming provides a route to configuration. The 56-pin QFN measures approximately 8 mm by 8 mm with a stated height of 0.90 mm, making it suitable for compact external hub assemblies.
The HX2LP architecture is intended for low-power USB 2.0 hub implementations. Shared upstream bandwidth means connected devices compete for the host link's available data rate, so a four-port hub does not provide four independent upstream channels. Port behavior also depends on firmware, EEPROM configuration, crystal timing, and the quality of the USB power and signal layout. The integrated termination resistors can simplify impedance-matched USB routing, but developers still need to follow the manufacturer's reference layout and power-distribution guidance.
Typical applications include four-port USB hubs, desktop and industrial docking stations, USB-to-multiport adapters, embedded USB expanders, and systems that need downstream port-status LEDs. A typical design connects the upstream port to a host, routes the four downstream differential pairs through controlled-impedance PCB traces, and uses the GPIO functions for activity or connection indicators. The supply network must remain stable across the attached-device load while minimizing switching noise and USB signal disturbance.
A critical design consideration is the distinction between electrical compatibility and full board-level equivalence. A replacement must preserve the 56-pin footprint, pin functions, clock requirements, power architecture, EEPROM interface, and firmware expectations; matching only the port count and USB version is insufficient. Designers should also validate downstream-port power-switching components, USB data-routing topology, and enumeration behavior as a complete subsystem.
This product data consolidates the verified distributor specifications, price reference, package information, family alternatives, and practical selection guidance. It highlights what can be confirmed from current sources and clearly identifies parameters that still require confirmation from the manufacturer datasheet before schematic release or PCB sign-off.

کاربردهای معمول
CY7C65630-56LFXA مناسب است برای 6 کاربردs: Four-Port Desktop USB Hub, Industrial USB-to-Multiport Adapter, USB Docking Station Expansion, Embedded USB Port Expander, USB Test and Measurement Front Panel, Legacy USB 2.0 Peripheral Hub.
Four-Port Desktop USB Hub
The CY7C65630-56LFXA fits a compact desktop hub that expands one upstream USB host connection into four downstream ports. Its four-port single-TT organization, 3.3 V supply, integrated USB termination resistors, and port-status indicator control reduce the amount of supporting circuitry needed around the controller. The implementation should route all USB differential pairs as controlled-impedance signals and provide local decoupling close to the 56-pin QFN. Because single-TT hubs share upstream bandwidth, connected devices should not be expected to sustain four independent USB 2.0 high-speed transfers simultaneously.
پیشنهادی
Industrial USB-to-Multiport Adapter
The CY7C65630-56LFXA can serve as the hub controller in an industrial adapter that exposes four USB 2.0 peripheral connections through a compact board. Its verified 0 °C to 70 °C operating range suits room-temperature equipment, while integrated termination and configurable status-indicator functions simplify the implementation. The design must verify downstream-port current limiting, power-switch behavior, connector protection, and thermal performance with the actual load. Firmware and EEPROM configuration also become important when the adapter must enumerate reliably across different host operating systems.
پیشنهادی
USB Docking Station Expansion
The CY7C65630-56LFXA is suitable for a docking station that needs a shared upstream USB connection and four downstream device ports. Its single-TT architecture efficiently adds connectivity without requiring four independent host controllers, while the 8 mm by 8 mm QFN package preserves board area. Layout engineers should keep the 24 MHz clock circuit short, provide the required local bypass capacitance, and route upstream and downstream USB pairs without stubs. The shared upstream link means data-intensive storage and display peripherals can contend for bandwidth.
پیشنهادی
Embedded USB Port Expander
The CY7C65630-56LFXA can expand USB connectivity in an embedded appliance that already has one host port but needs four external peripheral connections. Its low-power HX2LP family positioning is appropriate for compact systems where board area and external component count matter. The controller requires a stable 3.3 V rail, a 24 MHz external crystal, and programmed configuration for the intended port behavior. Developers should validate how the EEPROM content, GPIO assignments, and hub firmware interact with downstream power switches and product-specific status LEDs.
پیشنهادی
USB Test and Measurement Front Panel
The CY7C65630-56LFXA can be used in a USB test fixture or measurement front panel that connects several USB peripherals to one host controller. Its configurable port-status indicator control is useful for showing connection, activity, or fault states, and the integrated termination resistors can simplify the USB signal network. The 0 °C to 70 °C specification covers controlled indoor equipment. For safety and repeatability, the fixture should include protected power paths, clearly defined enumeration behavior, and tested firmware for every supported device class.
پیشنهادی
Legacy USB 2.0 Peripheral Hub
The CY7C65630-56LFXA remains relevant to repair, sustainment, and carefully controlled legacy projects requiring its established HX2LP behavior. Its four downstream ports and single-TT topology reproduce a conventional USB 2.0 hub arrangement without requiring newer SuperSpeed circuitry. The principal constraints are lifecycle and sourcing rather than basic functional capability: one distributor identifies the part as obsolete, while another currently lists inventory. Engineers should preserve the original footprint and firmware only after checking the complete pinout, package grounding, clock circuit, and power requirements in the manufacturer documentation.

یادداشت‌های طراحی
Treat the 56-pin QFN as a fine-pitch, high-density layout and follow the manufacturer reference layout for pad geometry, solder mask, and exposed-pad connection. Place input and output bypass capacitors close to their corresponding power pins, with particular attention to the 3.3 V supply. Do not infer the exposed-pad net from the generic QFN outline; verify ground versus alternate pad assignments in the exact datasheet before release.
Route the upstream and four downstream USB differential pairs as controlled-impedance PCB traces with continuous reference planes and minimal stubs. Keep the 24 MHz crystal loop compact, preserve the component placement shown by the manufacturer guidance, and isolate clocks from USB data routing. Differential pair length matching, connector escape geometry, and return-path continuity should be checked with the actual stackup rather than only by nominal trace length.
Design the 3.3 V rail for both controller demand and attached downstream-device loads without allowing port transients to corrupt the local hub supply. Use appropriate downstream power switching and current protection, and verify the source, startup behavior, and voltage tolerances against the exact datasheet. Because the verified material does not provide the complete absolute-maximum and recommended-operating tables, those values must be obtained before final schematic approval.
Do not treat every USB 2.0 hub controller with four ports as a physical substitute. Pin assignments, clock topology, EEPROM programming, GPIO functions, exposed-pad requirements, and firmware dependencies can differ even when the package count and USB speed match. The CY7C65630-56LTXC is the only close candidate found in the verified cross-reference data, and it still requires a complete side-by-side datasheet and firmware review before substitution.
