CY7C65620-56LTXA - USB 2.0 Hub Controller | Infineon
料号： CY7C65620-56LTXA ✗ 停产CY7C65620-56LTXA 概述
A USB hub controller is a semiconductor that manages traffic between a USB host and one or more downstream USB devices. Within the USB interface hierarchy, it sits below the host controller and above connected peripherals, adding transaction routing, device enumeration support, port-status monitoring, and configurable hub functions. USB 2.0 hub controllers therefore serve as interface ICs within broader USB connectivity systems.
The verified listings identify the CY7C65620-56LTXA as a USB 2.0 interface controller with a maximum clock frequency of 24 MHz. Related CY7C65620 ordering information describes a two-port single-TT hub with configurable GPIOs, LED indicator functions, and EEPROM capability. The package data identifies 56 terminals, a square no-lead form, package code HVQCCN, and an 8 x 8 mm body. The exact pin assignments are not reproduced here because the verified excerpt does not provide a complete manufacturer pin table.
Typical implementation places the controller at the center of a USB hub PCB, with upstream USB connectivity linked to the host and downstream ports connected through protected USB data and power paths. Firmware must also support required USB hub behaviors, including enumeration, configuration, suspend and resume handling, and port-status reporting. The controller does not remove the need for compliant power distribution, ESD protection, controlled-impedance routing, and connector implementation.
The CY7C65620 family is suitable for compact USB hubs, monitor or docking accessories, embedded USB routing products, and multiport peripherals that need a dedicated low-power hub controller. System designers should confirm voltage limits, temperature grade, crystal or clock requirements, transceiver configuration, and exposed-pad assembly details against the manufacturer datasheet before releasing a PCB.
Layout should preserve short USB differential traces, continuous reference planes, and symmetrical branch geometry, while keeping noisy power converters and inductors away from high-speed data paths. Input, output, and bypass capacitors must follow the values and placement specified by the manufacturer reference design. Because only distributor excerpts were available during verification, the page does not guess pinout details, absolute maximum ratings, or unverified electrical limits.
This page consolidates the verified distributor identity, package information, ordering variants, source links, and practical engineering context for CY7C65620-56LTXA. It also distinguishes documented same-family orderable variants from unsupported cross-brand replacements, helping engineers evaluate PCB reuse, sourcing, and design-in risk without treating functionally similar USB interface devices as pin-compatible substitutes.

典型应用
CY7C65620-56LTXA 适用于 6 应用s: Compact Two-Port USB Hub, USB Docking Station, Embedded USB Routing Product, USB Peripheral Sharing Hub, Instrument and Test Equipment, Monitor and Display Peripheral Hub.
Compact Two-Port USB Hub
The CY7C65620-56LTXA fits a compact two-port USB 2.0 hub because the verified family information identifies a two-port single-TT architecture with a maximum clock frequency of 24 MHz. Place the controller between the upstream host connection and downstream ports, then implement downstream power switching and USB data routing on the PCB. Its configurable GPIOs and LED-indicator capability simplify port-status monitoring without requiring additional discrete control devices. The 56-QFN 8 x 8 mm body also conserves board area compared with larger controller packages, although exposed-pad assembly and full signal integrity validation remain mandatory before production release.
推荐
USB Docking Station
A USB docking station can use the CY7C65620-56LTXA as the hub-control element when the design needs a two-port USB 2.0 routing fabric rather than a USB-to-serial bridge. The controller’s documented two-port single-TT topology, configurable GPIOs, LED-indicator support, and EEPROM capability support downstream-port enumeration and status indication. In a dense docking enclosure, the 56-QFN 8 x 8 mm package leaves more routing space than a larger controller, but designers still need controlled-impedance USB traces, ESD protection, compliant connector footprints, and independently protected downstream power rails.
推荐
Embedded USB Routing Product
The CY7C65620-56LTXA is appropriate for embedded products that need to expose two USB 2.0 ports while retaining a dedicated hub function. Its documented configurable GPIOs allow product-specific insertion or activity indicators, and EEPROM support can provide configuration or descriptor data where required. The controller’s 24 MHz maximum clock frequency must be reconciled with the reference crystal or clock implementation from the manufacturer design. Because the exact pinout was not included in the verified excerpts, PCB engineers should map every power, clock, data, and GPIO connection from the official CY7C65620 package drawing.
推荐
USB Peripheral Sharing Hub
The CY7C65620-56LTXA can serve as the central controller in a peripheral-sharing hub where two downstream USB devices need enumeration and independent port-status handling. The two-port single-TT family architecture is directly aligned with this use case, while configurable GPIO and LED functions can report connection state without burdening a separate host interface. The engineering trade-off is that the controller does not solve downstream power management by itself; each port still needs compliant current limiting, charging policy where applicable, ESD protection, and layout separation that preserves USB differential impedance.
推荐
Instrument and Test Equipment
Laboratory instruments and test systems can benefit from CY7C65620-56LTXA when multiple USB peripherals need a common connection to a host computer. The documented two-port topology provides a focused USB 2.0 routing function, while LED-indicator and GPIO support can communicate port status to the operator or enclosure. The 24 MHz maximum clock figure and 3.15 V to 3.45 V listed supply range make the device suitable for conventional embedded USB designs, provided the complete datasheet confirms clock tolerances, power sequencing, and operating-temperature requirements. EMI control is especially important around switching regulators and display or relay circuitry.
推荐
Monitor and Display Peripheral Hub
A monitor, display accessory, or multimedia peripheral can use the CY7C65620-56LTXA to manage two USB connections within a single enclosure. The compact 56-QFN 8 x 8 mm package helps preserve routing space around display connectors, while the two-port single-TT architecture supports a dedicated downstream hub function. Configurable GPIOs and LED indicators can be assigned to link, activity, or power status. Layout should separate this low-voltage controller area from display power converters, maintain continuous ground-plane return paths, and follow the manufacturer’s high-speed USB placement and decoupling recommendations.

设计说明
Route each USB 2.0 differential pair as a controlled-impedance, tightly coupled pair with continuous reference-plane return paths and no unnecessary stubs. Keep the upstream and downstream branches symmetric where practical, avoid crossing split planes, and follow the manufacturer’s reference layout for the 56-QFN footprint. Because the verified excerpts do not include the complete pin table, do not assign USB D+/D− or power pins from the package outline alone; verify every connection against the official pinout before layout release.
Implement the documented 3.15 V to 3.45 V supply range with local decoupling close to the controller and follow the manufacturer’s component values and exposed-pad connection requirements. USB downstream power switching is separate from the controller’s low-voltage core supply, so do not assume the controller can safely absorb connector current. Add appropriate port current limiting and verify startup, suspend, resume, and brownout behavior across the complete product power profile.
Separate switching regulators, inductors, and high-current downstream power paths from the USB controller and differential data routing. Keep the exposed-pad ground connection compact and provide a low-impedance ground reference under the device. Use common-mode filtering and ESD protection where required by the enclosure and connector exposure, but place protection devices so their parasitic capacitance does not degrade USB signal integrity. Validate emissions and immunity at the finished-product level.
Do not substitute a USB-to-serial interface IC merely because it also mentions USB High-Speed support. A hub controller must reproduce the required downstream-port routing, enumeration behavior, GPIO assignments, clock architecture, power pins, and package land pattern. Confirm grade, temperature, lead-free, AEC-Q100, and lifecycle status for the exact ordering suffix using the current manufacturer documentation before treating any CY7C65620 ordering variant as a production substitute.
合规信息
The verified excerpts do not explicitly state compliance status for the exact CY7C65620-56LTXA ordering code. A third-party index contains an AEC-related descriptor, but that wording is insufficient to establish AEC-Q100 qualification.
