MPN: CY7C65630-56LTXI ✓ فعالCY7C65630-56LTXI نمای کلی
A USB hub controller is a semiconductor that manages traffic between an upstream USB host and one or more downstream devices. It handles enumeration, port-state monitoring, power distribution, transaction routing, and status indication. The CY7C65630-56LTXI supports full-speed and high-speed USB operation, bus-powered and self-powered configurations, and a single transaction translator for compatible USB 2.0 system topologies.
Key features include support for four downstream ports, configurable GPIO functions, LED indicators, and optional EEPROM support. The device is identified in distributor data as an industrial-grade 56-pin QFN device with a sawn-style package and exposed pad. Its USB 2.0 compliance and USB-IF certification support help designers implement hub functions in equipment requiring interoperable host connectivity.
The CY7C65630 is related to the CY7C65620 within the EZ-USB HX2LP family, with port support serving as the principal functional distinction identified by the verified data. The controller can be configured through GPIO, LED, and EEPROM resources, allowing port status, enumeration behavior, and user-visible indications to be tailored to the finished hub product.
Typical applications include USB hubs, docking stations, industrial data-acquisition equipment, legacy USB expansion, KVM peripherals, and embedded systems that require multiple USB 2.0 downstream connections. Its 56-QFN package supports compact designs, but exposed-pad layout and power-delivery requirements demand careful PCB planning.
Designers should pay particular attention to upstream and downstream power budgets, especially when using self-powered operation. The exposed pad must be connected to the appropriate ground plane, input and output decoupling must be placed close to the device, and all USB data and power routing should follow the requirements of the manufacturer datasheet and applicable USB implementation guidance.
This product record combines verified distributor availability, the manufacturer ordering information, family-level hub features, and practical engineering guidance. It also distinguishes verified same-package drop-in candidates from alternatives that differ in package or port configuration, helping engineers reduce sourcing risk without treating merely similar USB controllers as direct replacements.

کاربردهای معمول
CY7C65630-56LTXI مناسب است برای 6 کاربردs: Compact USB 2.0 Hub, Industrial Docking Station, USB-to-Serial Data Acquisition, KVM and Peripheral Expansion, Legacy Computer USB Expansion, USB-Connected Test and Measurement Unit.
Compact USB 2.0 Hub
The CY7C65630-56LTXI fits a compact four-port USB 2.0 hub because it supports up to four downstream ports while presenting a single upstream connection to the host. The controller manages full-speed and high-speed device traffic through a single transaction translator and supports both bus-powered and self-powered hub configurations. In a self-powered product, the power architecture must budget each port separately and comply with USB current limits. The 56-QFN 8 x 8 mm package also requires careful exposed-pad grounding and short USB routing. Compared with using multiple smaller hub controllers, the four-port device can simplify host enumeration and reduce the number of upstream connections required by a computer or embedded system.
پیشنهادی
Industrial Docking Station
The CY7C65630-56LTXI is appropriate for an industrial docking station that connects several USB 2.0 peripherals to one host port. Four downstream-port support provides expansion for keyboards, storage devices, service interfaces, and data-acquisition peripherals without requiring a separate external hub. Its industrial-grade ordering option and operation up to 85 °C support use in factory equipment where ambient conditions exceed typical consumer-office temperatures. Designers should still validate the complete enclosure temperature, USB ESD protection, connector retention, and power-supply behavior. The self-powered mode is useful when attached devices require more current than a bus-powered connection can reliably provide.
پیشنهادی
USB-to-Serial Data Acquisition
The CY7C65630-56LTXI can serve as the hub controller in a USB-to-serial data-acquisition front end that combines multiple peripheral interfaces behind one compact host connection. Its support for full-speed and high-speed USB devices allows the hub to coexist with both low-speed control peripherals and high-speed storage or test devices. Configurable GPIO, LED-indicator, and EEPROM resources help implement port-status feedback, connection lighting, and configurable hub metadata. The industrial-grade suffix makes the controller relevant to laboratory and factory equipment, but the signal path must remain electrically isolated where required. System validation should include simultaneous enumeration, sustained-current loading, thermal performance, and compatibility with the intended Windows or embedded host software.
پیشنهادی
KVM and Peripheral Expansion
The CY7C65630-56LTXI is suitable for KVM and peripheral-expansion products that need several USB connections routed through one host port. Four downstream ports allow keyboards, mice, storage, and service interfaces to share an upstream link, while configurable GPIO and LED functions can provide port activity or connection-status indication. The single-translator architecture is specified for the EZ-USB HX2LP family, simplifying integration within the intended USB 2.0 topology. In a KVM enclosure, cable losses and ground offsets can affect reliability, so the designer should preserve the layout guidance in the manufacturer datasheet and avoid long unprotected USB traces. Firmware and enumeration behavior must also be checked when moving between lower-port family members.
پیشنهادی
Legacy Computer USB Expansion
The CY7C65630-56LTXI can add USB 2.0 expansion to a legacy computer or embedded platform that has limited host-controller resources. Up to four downstream ports reduce the need to reassign internal USB host ports, while full-speed and high-speed operation supports a broad range of peripherals. The controller is most appropriate when the host already has a compatible USB host connection and the product needs standardized downstream-port behavior. Software qualification is essential because hub enumeration, power states, and device topology can differ from direct host connections. For an industrial legacy system, the LTXI ordering option and verified operation to 85 °C are relevant advantages, but enclosure temperature and power-budget testing remain required.
پیشنهادی
USB-Connected Test and Measurement Unit
The CY7C65630-56LTXI fits a USB-connected test or measurement instrument that needs to expose several service peripherals through one upstream port. Four downstream ports can support a control interface, storage device, status display controller, and service adapter, while LED and GPIO configuration enables clear operator feedback. The industrial-grade option is useful where the instrument operates in a factory or laboratory enclosure with elevated ambient temperature. Signal-integrity and safety checks are particularly important because test equipment may combine sensitive analog circuitry with USB switching and power conversion. Use the official reference layout and power recommendations, keep high-current switching nodes away from data inputs, and verify simultaneous operation across all attached ports before production.

یادداشت‌های طراحی
Determine whether the finished hub is bus-powered or self-powered before committing the PCB. The verified controller family supports both modes, but self-powered designs must budget upstream current and every downstream port separately, account for inrush, and prevent port power from disturbing the controller and USB data rails. Use the voltage limits, decoupling values, and power-routing guidance in the manufacturer datasheet rather than estimating from generic USB rules.
The CY7C65630-56LTXI uses a 56-QFN package with an exposed pad on an 8 x 8 mm body. Follow the official HVQCCN land pattern exactly, provide solder mask and paste apertures according to the package drawing, and connect the exposed pad to the intended ground network. Place decoupling capacitors close to the relevant supply and ground pins, and route D+ and D− differentially with matched geometry and a continuous reference plane.
Keep USB data traces away from switching power nodes, inductors, and high-current downstream-port paths. The controller's four downstream connections should have controlled impedance and minimized stubs. Review the pinout and reference layout in the official manufacturer material before assigning connector positions because connector placement can force long return paths or split ground planes. Validate the finished board for enumeration, hot-plug behavior, and simultaneous high-speed traffic.
Do not approve a lower-port CY7C65620 variant solely because it uses the same 56-QFN footprint. Verify unused port connections, required pull resistors, GPIO assignments, and firmware assumptions on a no-load prototype. Likewise, do not infer that every ordering suffix has identical qualification or temperature coverage. Obtain the current manufacturer ordering table and confirm that the selected alternative matches the production configuration required by the application.
