A USB hub controller is an interface integrated circuit that manages traffic between one upstream USB connection and multiple downstream peripherals. The CY7C65620 belongs to the broader hierarchy of USB interface controllers, which sit between a host system and USB peripherals. Its two-port architecture is useful where a compact embedded system, docking station, printer, industrial control panel, or test fixture must expand one host USB connection into multiple device connections. The supporting EZ-USB HX2LP family is also identified as configurable with GPIOs, LED indicators, and EEPROM support.
Key features include USB 2.0 compatibility, two-port hub operation, Full-Speed and High-Speed device support, and a 3.3 V operating supply identified in the verified distributor data. The 56-QFN exposed-pad package supports dense surface-mount layouts and provides a thermal connection to the PCB through its exposed pad. The controller also supports full-speed and high-speed devices, allowing a single hub design to accommodate different USB peripheral classes rather than restricting operation to low-speed devices.
Technically, the CY7C65620-56LTXI is an EZ-USB HX2LP-family hub controller offered in a 56-QFN EP configuration. The package measures 8 mm by 8 mm according to distributor data. The controller consolidates USB hub interface logic, port-status support, and configurable GPIO, LED-indicator, and EEPROM features into one device. This integration reduces the number of discrete devices required around a USB hub implementation while preserving configurable behavior for downstream-port status and connection management.
Typical applications include industrial USB expansion panels, peripheral-sharing equipment, docking stations, embedded host systems, and USB test benches. In these systems, the two downstream ports can serve keyboards, storage devices, diagnostic adapters, or other compatible peripherals. A board designer should still validate enumeration behavior, port power requirements, high-speed routing, crystal or clock requirements, and exposed-pad soldering against the manufacturer datasheet before releasing a production PCB.
The primary design consideration is USB signal integrity. High-speed USB traces require a controlled 90-ohm differential impedance, continuous reference planes, minimized stub branches, and careful connector and controller placement. Decoupling, exposed-pad thermal management, and USB power-enable sequencing also require attention. The verified public snippets do not expose the complete pinout, timing tables, absolute maximum ratings, or detailed power-consumption figures, so those values should be confirmed in the manufacturer datasheet.
This page consolidates distributor availability, verified package and interface details, family-level configuration information, drop-in alternatives, and practical implementation guidance. It also distinguishes confirmed specifications from missing data, helping engineers evaluate the CY7C65620-56LTXI without inferring unsupported pin-level or electrical values.

일반적인 애플리케이션
CY7C65620-56LTXI 적합 용도: 6 애플리케이션s: Industrial USB Expansion Panel, USB Docking Station, Embedded USB Test Fixture, Peripheral Sharing Equipment, Embedded Host Access Panel, Portable USB Connection Hub.
Industrial USB Expansion Panel
The CY7C65620-56LTXI fits an industrial USB expansion panel because it provides a two-port USB 2.0 hub controller with Full-Speed and High-Speed device support at a 3.3 V operating supply. Its configurable GPIO, LED-indicator, and EEPROM capabilities allow the design to report downstream-port status and implement configurable behavior without a separate general-purpose controller. The 56-QFN exposed-pad package also supports compact surface-mount construction. During implementation, preserve the manufacturer USB 2.0 routing rules and connect the exposed pad to the recommended thermal plane. Industrial qualification still requires checking the operating-temperature grade, EMC requirements, and long-term availability because these details are not established by the supplied distributor snippets.

USB Docking Station
A USB docking station can use the CY7C65620-56LTXI to turn one upstream host connection into two downstream USB ports. The controller's USB 2.0 support, 480 Mbps maximum data rate, and compatibility with both Full-Speed and High-Speed peripherals make it suitable for storage peripherals, input devices, and service interfaces. The verified family information also identifies configurable GPIOs and LED indication, which help implement port-status or device-presence functions. Layout is the primary engineering concern: route the high-speed differential pairs over a continuous ground plane, control the 90-ohm differential impedance, and position the controller close to power-distribution and ESD-protection components.
추천
Embedded USB Test Fixture
The CY7C65620-56LTXI is appropriate for an embedded USB test fixture requiring two downstream ports and a single 3.3 V controller supply. Its two-port Single-TT hub architecture can organize device-under-test connections, while configurable GPIO and LED functions can expose link or port status to the fixture controller. High-speed operation requires careful connector placement, short differential routes, an uninterrupted reference plane, and ESD protection selected for USB data lines. Because the public snippets do not expose the complete timing, power, or absolute-maximum-rating tables, validation should use the official manufacturer datasheet for test limits and enumeration behavior.
추천
Peripheral Sharing Equipment
The CY7C65620-56LTXI can support peripheral-sharing equipment where a compact host interface must serve two USB devices. Full-Speed and High-Speed support allows the fixture to combine lower-speed control peripherals with high-speed storage or data-transfer devices. Its configurable EEPROM and LED capabilities can assist with identifying connected ports, while the 3.3 V supply matches the operating level stated in the verified listings. For a production design, verify downstream-port power-switching requirements, current limits, and whether external hub power is needed; those implementation values are not present in the supplied snippets and should be obtained from the manufacturer datasheet.
추천
Embedded Host Access Panel
The CY7C65620-56LTXI is suitable for an embedded host access panel that exposes service, storage, and configuration ports through one upstream USB interface. The controller's two downstream ports provide a practical balance between expansion and board area, while its configurable GPIO features can assist with port-enable or status signaling. The 56-QFN EP package requires a land pattern that accommodates its exposed thermal pad and careful assembly-process control. Designers should also confirm device enumeration, power sequencing, and suspend/resume behavior against the official documentation. These functional checks are essential because the verified search results identify the hub architecture and package but do not publish detailed timing or power-management tables.
추천
Portable USB Connection Hub
The CY7C65620-56LTXI can be used in a portable USB connection hub where two downstream ports are needed within a compact 8 mm by 8 mm controller package. Its low-power EZ-USB HX2LP family positioning is useful for space-constrained portable equipment, while Full-Speed and High-Speed support covers common keyboards, storage devices, and service peripherals. The exposed pad helps remove heat from the IC, but it must be connected to a suitable copper area according to the manufacturer layout guidance. Portable-product validation should include suspend current, bus-powered versus self-powered operation, connector ESD resilience, and device-removal behavior, none of which are quantified in the supplied verified snippets.

설계 노트
Route all USB 2.0 high-speed differential pairs as a controlled 90-ohm impedance over a continuous reference plane. Keep the controller-to-connector path short, eliminate unnecessary test pads and stubs, and avoid plane changes beneath the pairs. The exposed-pad footprint and exposed-pad pin assignment must follow the manufacturer package drawing. The supplied sources confirm a 56-QFN EP package but do not provide the complete pinout, so consult the official schematic and layout guidance before routing.
Design the 3.3 V rail with short, symmetrical power paths and place the datasheet-recommended bypass capacitors immediately beside the supply and ground pins. USB downstream-port power switching is not described in the verified snippets, so determine whether VBUS must be externally supplied, switched, or individually controlled. Verify startup sequencing, current limits, and bus-powered versus self-powered operation against the manufacturer datasheet rather than deriving them from the hub-controller description.
The 56-QFN exposed pad is the primary thermal path for the controller. Use the manufacturer land pattern with all thermal vias populated and connect the pad to the recommended ground or thermal plane, while observing assembly constraints for solder voiding under the pad. Actual dissipation depends on the complete electrical and bus-utilization conditions, which are not provided in the verified snippets. Measure junction-temperature rise in the final enclosure if sustained downstream traffic or elevated ambient temperature is expected.
Do not treat a shared family name or identical 56-QFN outline as proof of interchangeability. Verify the exact order-code pinout, clock source, operating-temperature grade, USB timing, power behavior, and lifecycle status for CY7C65620-56LTXI against any proposed CY7C65620 or CY7C65630 alternative. The verified cross-reference results provide family and package information but do not establish complete electrical equivalence, so a prototype comparison and schematic review remain necessary.
규정 준수 정보
The supplied verified results do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred.
