CY7C65620-56LFXCT

CY7C65620-56LFXCT - 2-Port USB 2.0 Hub Controller | Infineon

The Infineon Technologies CY7C65620-56LFXCT is a low-power USB 2.0 hub controller in a 56-pin QFN package measuring 8 mm by 8 mm. It provides two downstream USB ports, 480 Mbps full-speed and low-speed operation, and an integrated 24 MHz PLL that works with an external crystal. Integrated upstream and downstream termination resistors reduce external component count and simplify USB board layout. A USB hub controller is a system-on-chip that connects one host USB interface to multiple downstream peripherals while handling port enumeration, signaling, power management, and status indication. In the product hierarchy, this device is a USB interface IC, a USB hub controller, and ultimately a connectivity semiconductor for personal computers, peripherals, docking systems, industrial equipment, and embedded USB hosts. Key features include two USB 2.0 ports, integrated upstream and downstream termination resistors, configurable port status indicator control, and in-system EEPROM programming. The controller can also use an external SPI EEPROM for configurable USB descriptor data such as vendor ID and product information. A 24 MHz external crystal with an integrated PLL supplies the internal timing reference required for reliable USB data transfer. The CY7C65620 belongs to the CY7C656xx low-power hub controller family, which operates from a 3.45 V supply and supports USB data rates up to 480 Mbps. Its 56-pin QFN-56 construction is intended for compact, high-density PCB assemblies. The 8 mm by 8 mm footprint requires careful escape-routing of USB differential pairs and controlled layout around the crystal, supply, and termination networks. Typical applications include two-port USB hubs, desktop and notebook peripherals, printer or scanner adapters, external storage enclosures, industrial USB distribution panels, and embedded host systems that need one upstream port and two downstream ports. Configuration flexibility through GPIO-controlled status indicators and programmable USB descriptors supports product-specific behavior without redesigning the hub controller. When laying out the board, route the upstream and downstream USB pairs as controlled-impedance, differentially coupled traces with no stubs or test pads in the pairs. Place the 24 MHz crystal close to its assigned pins and keep the crystal loop compact. Verify the hub enumeration, suspend, over-current, and downstream-port disable behavior in the final system because firmware and descriptor configuration determine much of the user-visible behavior.

CY7C65620-56LTXA

CY7C65620-56LTXA - USB 2.0 Hub Controller | Infineon

Infineon Technologies CY7C65620-56LTXA is a low-power USB 2.0 hub controller with a 24 MHz maximum clock frequency, presented in a 56-QFN 8 x 8 mm package. The device is associated with a two-port, single-TT hub architecture that can be configured through general-purpose I/O, LED indicators, and optional EEPROM support. Its no-lead package supports compact integration in external USB hubs, docking stations, computer peripherals, and embedded USB-routing equipment. 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.

The commercial C-grade device includes configurable GPIO resources, LED indication, and EEPROM support for configurable hub behavior. A USB hub controller is an interface integrated circuit that manages one upstream USB connection and multiple downstream ports. It belongs to the hierarchy of USB interface controller, interface IC, and integrated circuit. Rather than duplicating full host-controller logic in every peripheral, a hub controller centralizes port enumeration, power-management coordination, status signaling, and downstream traffic management across a USB 2.0 peripheral or host system. The CY7C65620 provides two downstream ports and a 480 Mbps high-speed data rate. Its 3.45 V operating capability aligns with 3.3 V USB transceiver implementations. GPIO configuration allows product-specific behavior, LED indicators can report port activity or status, and EEPROM support enables configuration information to be retained or supplied by the system designer. These features are useful when a product requires a compact two-port hub without using a larger external hub implementation. The controller belongs to the EZ-USBTM HX2LP family and is identified as a two-port Single-TT hub solution. The 56-QFN 8 x 8 mm package supports compact integration but requires careful exposed-pad thermal and layout management. The product is available in bulk packaging according to the manufacturer listing. Infineon markets the device with configuration, ordering, parameter, and datasheet information on its official component page. Typical applications include USB 2.0 peripheral hubs, embedded host systems, docking equipment, printer or storage interfaces, and industrial control panels that need more than one USB connection. In these systems, the controller can reduce the number of dedicated USB interface blocks while preserving high-speed signaling. Firmware and board validation remain essential because downstream-port behavior, enumeration, and indicator management must match the complete product architecture. Designers should place the USB differential pairs on a controlled-impedance PCB, keep the exposed pad and power connections compliant with the manufacturer layout guidance, and validate both full-speed and high-speed operation. Power budgeting, inrush behavior, cable faults, and LED-current limits should be checked before production release. The available public snippets confirm the core USB and package characteristics but do not expose every electrical limit, so the manufacturer datasheet remains the controlling design reference. This page consolidates verified manufacturer and distributor information, price context, package details, and design-oriented guidance. It also distinguishes confirmed drop-in candidates from unrelated USB interface devices, helping engineers evaluate replacement options without confusing functional similarity with true pin-to-pin compatibility.

The device provides configurable GPIOs, USB port LED indication, and EEPROM support, making it suitable for managed USB hub implementations that require more than simple power distribution. Its tape-and-reel shipping configuration and C-grade temperature designation identify it as a production ordering option for USB interface equipment. A USB hub controller is an interface integrated circuit that manages traffic between one upstream USB host connection and multiple downstream USB ports. Within the device hierarchy, the CY7C65620 belongs to the class of USB interface controllers, bus controllers, and broader interface integrated circuits. Its two-port single-TT configuration provides a practical way to consolidate USB peripheral connections while keeping host-interface decoding and downstream-port control in one dedicated component. The principal features supported by the manufacturer information are USB 2.0 operation, two downstream ports, single-TT topology, configurable GPIOs, LED indicator support, and EEPROM support. The 56-QFN package has 56 no-lead terminals and a square 8 mm by 8 mm body. These characteristics make the controller appropriate for compact external hubs, embedded USB port expanders, docking equipment, and industrial computers whose downstream ports require controlled bus transactions. The controller is intended to operate with a USB host and downstream USB peripherals while supporting configuration through general-purpose I/O and optional nonvolatile hub metadata. Configurable GPIOs provide a way to connect device-control signals such as port indicators or system-control functions. EEPROM support can assist systems that require persistent configuration data, while the dedicated port-control capability remains distinct from a passive USB power hub. Typical applications include two-port desktop USB hubs, printer and storage adapters, embedded systems requiring USB port expansion, industrial control panels, and test equipment that needs repeatable downstream-port behavior. Board layout must preserve the 56-QFN land pattern, adequate exposed-pad thermal treatment if the package configuration provides one, and the decoupling and signal-routing practices specified by the manufacturer datasheet. When choosing a replacement, verify the exact package, terminal arrangement, temperature grade, and shipping format rather than relying only on the controller family name. The CY7C65620-56LTXC, CY7C65620-56LTXI, and CY7C65620-56LTXIT share the controller and 56-pin QFN format but use different ordering formats. Confirm the appropriate ordering code against production assembly requirements. This page consolidates the manufacturer ordering details, package information, practical application guidance, comparison parameters, and verified drop-in ordering options into a design-oriented resource. It also distinguishes electrical controller compatibility from assembly-format selection so engineers can make a traceable replacement decision.

It supports both Full-Speed and High-Speed USB operation and is packaged in a 56-pin QFN with exposed pad. The component is identified as a 3.3 V single-TT hub controller and is supplied in tray packaging. These specifications position the device as a dedicated USB interface IC for systems that require centralized control of two USB downstream ports. 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.

It integrates USB 2.0 compliance, an upstream port, and two downstream ports on a single chip, replacing discrete hub designs with a compact surface-mount solution. A USB 2.0 hub controller is a class of interface IC that expands one upstream USB port into multiple downstream ports, handling transaction translation (TT), signal conditioning, and protocol compliance. The HX2LP Lite family belongs to Infineon's USB hub controller hierarchy, sitting between USB transceivers (physical layer only) and full USB host controllers (which add host-role processing). This positions the CY7C65621 as a self-contained USB 2.0 hub IC suitable for embedded systems without an internal root hub. Key features include USB 2.0 compliance at low-, full-, and high-speed (480 Mbps), integrated upstream and downstream transceivers, single-TTT transaction translation, bus-powered or self-powered operation, and per-port overcurrent detection. The 56-QFN package provides a low-profile footprint for space-constrained designs such as docking stations, monitors, and embedded motherboards. The CY7C65621 employs a serial interface engine plus a hub repeater architecture, offloading USB protocol overhead from the system processor. Per-port overcurrent sensing and ganged-power-switching reduce BOM cost, while internal pull-up/pull-down resistors simplify PCB layout by removing most external USB components. Typical applications include USB 2.0 hubs and docking stations, monitors with integrated USB ports, embedded motherboards, industrial USB expansion modules, and consumer peripherals such as printers. The wide operating voltage and low suspend current also make it suitable for battery-powered USB expansion accessories. When designing with this device, follow Infineon's reference schematic for USB impedance-controlled routing (90 ohm differential) and place the 24 MHz crystal within 5 mm of the XTALIN/XTALOUT pins. Decouple VBATT and VDD with 1uF ceramic capacitors placed within 2 mm of the respective pins.

The Infineon CY7C65621-56LTXCT is a 4-port, USB 2.0 hub controller from the EZ-USB HX2LP Lite low-power family, supplied in a 56-pin QFN (8x8 mm) package with 0.90 mm height. It implements a USB 2.0 high-speed hub with integrated upstream and downstream termination resistors, integrated port status indicator control, and a 24 MHz external crystal with internal PLL. The device operates from a single 3.3 V supply and supports bus-powered and self-powered topologies. A USB hub controller is a protocol-aware bridge that expands one upstream USB port into multiple downstream ports while handling the USB 2.0 hub specification, including transaction translator (TT) logic, port power switching coordination, and over-current protection signaling. The HX2LP Lite family sits in the broader product hierarchy of USB interface IC -> interface IC -> integrated circuit, and is engineered specifically for low-power embedded hubs where standby current, BOM cost, and PCB area are critical. Key features include support for USB 2.0 high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) signaling, in-system EEPROM programming via SPI for vendor ID, product ID, and port customization, integrated upstream and downstream termination resistors that eliminate external components, and integrated LED status indicator drivers per port. The CY7C65621 variant provides four downstream ports, while the related CY7C65631 variant targets two-port designs. From an architectural perspective, the HX2LP Lite integrates the physical layer (PHY), serial interface engine (SIE), hub repeater, transaction translator, and power-management state machine into a single die. This integration reduces external component count compared to discrete hub designs, where multiple transceivers and a separate hub controller IC are required. According to the Cypress/Infineon datasheet, the integrated PLL derives all required USB clocks from a single 24 MHz crystal, eliminating the need for an external clock generator. Typical applications include USB port expansion on laptops, docking stations, monitors with built-in USB hubs, embedded industrial PCs, and consumer electronics such as set-top boxes and game consoles. The commercial temperature grade (0C to +70C) suits indoor commercial environments. When designing with this device, allocate 10 uF plus 0.1 uF ceramic bypass capacitors close to the 3.3 V supply pin, route the USB 2.0 differential pairs (D+/D-) with 90 ohm differential impedance, and ensure the upstream port's VBUS sensing resistor is selected per the USB 2.0 bus-power budget. The 56-QFN package requires thermal relief on the exposed pad connected to the ground plane.

CY7C65621-56LTXI USB 2.0 Hub Controller | Infineon

Infineon Technologies CY7C65621-56LTXI is a two-port USB 2.0 hub controller supporting Full Speed and High Speed operation in a 56-QFN package. The verified product information identifies a 3.3 V device, an integrated USB Serial Interface Engine for host communication, and support for a two-port single-TT bus-powered application. Its 56-pin QFN package measures 8 mm by 8 mm and includes an exposed pad. A USB hub controller is an interface integrated circuit that coordinates traffic between a USB host and multiple downstream peripherals. Within the hierarchy of USB interface controllers, hub controllers, interface ICs, and semiconductors, it provides device enumeration, downstream-port management, and shared host connectivity. The target part is therefore useful when one USB host connection must fan out to two USB devices without relying on a host-side software hub. The verified data highlights Full Speed and High Speed USB 2.0 operation, two downstream ports, a 3.3 V supply, and a single-TT bus-powered configuration. The Serial Interface Engine allows the controller to communicate with the USB host, while the QFN exposed-pad package supports compact surface-mount construction and board-level heat spreading. The I-grade ordering code is explicitly identified by the manufacturer for the two-port bus-powered application. The CY7C65621 family is intended for USB hubs and related interface equipment where deterministic downstream-port control is required. Compared with a four-port hub controller, the two-port architecture can fit installations that need exactly two ports and may simplify enclosure, cable, and power-budget considerations. Firmware, descriptor configuration, downstream transceiver characteristics, and detailed electrical limits should be checked in the manufacturer datasheet before board release. Typical installations include compact USB hubs, bus-powered accessories, embedded USB expansion equipment, and two-port docking products. The device can sit between a host controller and two downstream connectors, provided the board implements the required USB routing, decoupling, protection, and exposed-pad thermal construction. USB signal integrity is especially important because high-speed edges and connector launches can introduce reflections and loss. For a new design, use the manufacturer ordering information and datasheet to confirm pin assignments, supported operating modes, crystal or clock requirements, power sequencing, and transceiver layout. Treat the published 3.3 V value as the verified supply figure, but verify every electrical limit and application guideline in the official documentation.

CY7C65630-56LFXA

CY7C65630-56LFXA - 4-Port USB 2.0 Hub | Infineon

The Infineon CY7C65630-56LFXA is a four-port, single-TT USB 2.0 hub controller with a 3.3 V supply, 56-pin QFN package, integrated USB termination resistors, configurable GPIO port-status indicators, and support for a 24 MHz external crystal with an integrated PLL. The device belongs to the EZ-USB HX2LP low-power USB hub controller family and targets USB connectivity designs requiring four downstream ports. 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.

It belongs to the EZ-USB HX2LP family and is designed for USB hub designs requiring integrated USB signal conditioning and low system cost. The manufacturer describes the CY7C65620 and CY7C65630 devices as high-performance USB 2.0 hub solutions with integrated 1.5 kΩ upstream pull-up resistors, 15 kΩ downstream pull-down resistors, and series termination resistors on the upstream and downstream D+ and D- pins. 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.

CY7C65630-56LFXC - 4-Port USB 2.0 Hub Controller | Infineon

Infineon Technologies CY7C65630-56LFXC is a low-power USB 2.0 hub controller with four downstream ports, 3.3 V operation, and a 56-QFN 8 x 8 mm package. It is designed for embedded USB hub implementations where a dedicated controller consolidates USB connectivity, port-status control, and downstream-device management on one integrated circuit. The part belongs to the EZ-USB HX2LP controller family and is identified by distributor listings as a four-port, single-Transaction-Translator USB hub controller. A USB hub controller is an interface integrated circuit that manages the shared USB bus between a host and multiple downstream peripherals. Within the broader semiconductor hierarchy, it is a USB interface controller, then a USB interface IC, and finally an integrated circuit. The controller sits between a USB host and downstream ports, helping implement the physical and logical topology required for multi-device USB connections while reducing the host-processing burden associated with repeated device enumeration and port management. The CY7C65630-56LFXC provides USB 2.0 compliance and four configurable hub ports. According to the manufacturer datasheet, the family also includes an automotive and industrial temperature option covering -40 C to +85 C, making it relevant to systems requiring extended-temperature operation. Its low-power designation supports use in compact embedded and portable equipment where energy efficiency and board area matter. The 56-QFN package provides a surface-mount integration option without the larger footprint of a conventional through-hole controller. The controller is configured through general-purpose input/output resources, LED indication, and optional EEPROM support, as stated in the manufacturer product information for the related four-port device. These functions allow a designer to implement port-enable behavior, status indicators, and hub identity or configuration storage in the surrounding system. The EEPROM-dependent behavior is especially useful when equipment requires consistent enumeration after power cycles or coordinated startup with another embedded controller. Typical uses include industrial USB aggregation, automotive passenger-compartment accessories, kiosk and point-of-sale equipment, desktop or docking systems with several low-speed peripherals, and embedded test equipment. In each case, the key benefit is centralized downstream-port control. The controller is intended for a USB 2.0 host environment; it does not increase the signaling rate of an upstream USB 2.0 link, and actual usable throughput remains constrained by the host, device classes, cable quality, and shared bus bandwidth. Designers should verify the exact pin assignments, electrical limits, reference-design support circuitry, and USB compliance details in the manufacturer datasheet before layout release. Pay particular attention to power-supply distribution, USB data-routing geometry, ground continuity, capacitor placement, and thermal performance. The available verified source set does not provide the complete electrical characteristics table or the full 56-pin assignment, so those items must be confirmed directly from the official datasheet. This page combines verified distributor identification, package information, lifecycle and replacement findings, drop-in alternatives, and practical implementation guidance. It also distinguishes the confirmed electrical facts from parameters that still require datasheet confirmation, providing engineers with a clearer basis for sourcing, comparison, and design review.

Infineon Technologies CY7C65630-56LFXCT is a four-port, single-transaction-translator USB 2.0 hub controller in a 56-pin QFN package measuring 8 mm by 8 mm. It is based on the CY7C65620/CY7C65630 EZ-USB HX2LP low-power hub controller family and is intended for USB hubs, docking stations, kiosk systems, printers, and other multi-device USB peripherals. A USB hub controller is an interface IC that manages traffic between one upstream USB host connection and multiple downstream USB ports. It coordinates enumeration, packet routing, power management, and device attachment across the hub. The CY7C65630 family integrates 1.5 kΩ upstream pull-up resistors for full-speed operation, 15 kΩ downstream pull-down resistors, and series termination resistors on upstream and downstream D+ and D- signals. The CY7C65630-56LFXCT provides four downstream USB 2.0 hub ports through configurable GPIO resources. Its configuration supports port indicators and EEPROM-based setup, while the integrated bus resistors help reduce external component count. The low-power architecture is intended for compact USB 2.0 systems where board area and component count are important. The 56-QFN package also supports compact surface-mount construction in docking and embedded USB equipment. The 56LFXCT ordering code identifies a 56-pin QFN package. Infineon lists the related CY7C65630-56LTXC as a 4-port, single-TT hub with configurable GPIOs, LED indicators, EEPROM support, and a 56-pin QFN package. The related LFXC-to-LTXC change is attributed by Infineon to package singulation, with the sawn-type package supporting a more reliable supply source. For implementation, treat D+ and D- routing as a controlled-impedance USB task. Keep upstream and downstream differential pairs routed as short, continuous pairs away from switching nodes and noisy clocks. Follow the manufacturer’s recommended capacitor placement and provide the downstream-port overcurrent and power-distribution arrangements required by the target USB design. This page combines manufacturer-family details, package information, ordering-code distinctions, replacement guidance, and practical USB hub design considerations. It also identifies the limits of the available substitution information so engineers can distinguish documented same-family replacements from parts that would require independent pin and firmware validation.

A USB hub controller is a bus-interface integrated circuit that coordinates communication between one upstream USB host and multiple downstream ports. It sits within the broader hierarchy of interface controller, USB interface IC, USB hub controller, and semiconductor. Unlike a general-purpose microcontroller, the dedicated hub controller incorporates USB host and device interface functions specifically organized for hub topologies. Its exact port count, transfer rates, clocking requirements, and supported operating modes should be confirmed against the manufacturer datasheet before schematic capture. The CY7C65630-56LTXA is identified in distributor listings as a USB 2.0 USB Interface controller. The verified product listings place it in the Bus Controllers and Interface Controllers classes, supporting use in hubs, docking stations, card readers, embedded USB expansion systems, and industrial peripherals. The compact 8 mm by 8 mm QFN package is useful where connector density and board area constrain the design. Thermal and layout planning are especially important for this no-lead package. The exposed ground structure must be connected to a low-impedance ground plane, while supply and interface routing should follow the reference layout and decoupling guidance in the manufacturer documentation.

The CY7C65630-56LTXA is available from multiple authorized distributors, with DigiKey and Mouser listings present at the time of verification. Quote-based procurement can be appropriate when stock and lead time fluctuate. The family also includes related 56-QFN ordering variants, but suffix changes can indicate package construction or grade differences rather than unconditional functional interchangeability. This page consolidates distributor availability, package information, related same-family MPNs, and practical integration considerations. It also distinguishes verified facts from engineering values that still require confirmation from the official datasheet, preventing package-only substitutions from being presented as automatic drop-in replacements.

Configuration GPIOs can be assigned to hub activity indicators or other system functions, while EEPROM support can simplify port-specific initialization. In a self-powered design, the hub supply must provide the power required by connected downstream devices rather than relying entirely on upstream bus current. Designers should verify the exact pin assignments, power requirements, crystal or clocking requirements, port-routing options, and exposed-pad connection against the manufacturer datasheet before layout. The saw-type QFN construction requires careful assembly-process compatibility checks and adequate thermal-via implementation beneath the exposed pad where applicable. Production designs should also confirm USB-IF certification requirements and the exact operating-temperature grade for the intended deployment. This product record combines the official Infineon device description with distributor and cross-reference evidence. It distinguishes verified hub capabilities from unavailable electrical details, identifies the documented relationship to the CY7C65630-56LFXC, and provides design-oriented guidance for USB hub implementation without inventing unverified pin assignments or prices.

It operates from a 3.15 V to 3.45 V supply, supports a 0 °C to +70 °C temperature range, and provides integrated USB upstream and downstream termination resistors. The device includes an integrated PLL for use with a 24 MHz external crystal, configurable GPIOs, port-status LED control, and in-system EEPROM programming. A USB hub controller is an interface IC that manages one upstream USB connection and multiple downstream ports while handling enumeration, power-gating, overcurrent response, and transaction routing. The CY7C65630 belongs to the USB interface controller hierarchy, where USB 2.0 describes the bus speed and protocol generation. Its four-port single-TT architecture is intended for compact USB hubs, docking stations, monitor hubs, and embedded systems that need reliable downstream port expansion without a discrete host controller for each port. Key device features include four downstream USB ports, integrated termination resistors, configurable general-purpose I/O pins, port-status indicator control, and EEPROM support for configuration storage. The integrated PLL accepts a 24 MHz reference crystal, while the in-system EEPROM programming function allows device configuration to be updated without a separate programming fixture. These features reduce the external component count and simplify firmware-based hub configuration. The device is intended for 3.3 V operation. The manufacturer specifies a 3.15 V minimum and 3.45 V maximum operating supply, with a listed operating supply current of 231 mA. Because hub controllers coordinate multiple USB data paths, the design must preserve controlled-impedance routing between the upstream port, downstream ports, and external 24 MHz crystal network. Typical uses include four-port USB 2.0 hubs, USB docking stations, shared-access peripherals, industrial USB expansion boards, and compact consumer accessories. The 56-pin QFN footprint also suits designs where connector placement and routing space are constrained. Tape-and-reel packaging supports automated assembly, and the C-grade ordering designation identifies the manufacturer's commercial temperature grade for this configuration. When laying out the board, place the crystal and its load components close to the oscillator pins, provide continuous ground and power planes, and route each USB differential pair as a controlled-impedance pair without test pads or stubs. Decoupling capacitors should connect directly to the relevant supply and ground pins using short traces and via stitching. Verify downstream overcurrent handling, port enable sequencing, and USB enumeration behavior across the intended attachment sequence. This page combines manufacturer ordering information, interface and package characteristics, practical PCB guidance, and qualified same-footprint alternatives for engineers evaluating the EZ-USB HX2LP hub controller platform.

Infineon Technologies CY7C65630-56LTXIT is a 4-port, single-TT USB 2.0 hub controller configured with general-purpose I/O, LED indicators, and EEPROM support, housed in a 56-QFN package measuring 8 mm by 8 mm. It operates from a 3.15 V to 3.45 V core supply and is supplied in tape-and-reel packaging with an industrial temperature grade. A USB hub controller is an interface integrated circuit that coordinates traffic between one upstream USB host and multiple downstream peripherals. It belongs to the USB interface controller family, a branch of interface ICs within the broader semiconductor hierarchy. Single-TT operation means that the controller uses one transaction translator to support its downstream USB functions, making it suitable for managed USB 2.0 hubs where device traffic must be segmented between a host connection and attached peripherals. The CY7C65630 provides four downstream USB ports, configurable GPIO resources, LED-indicator support, and EEPROM support for hub metadata. These features allow a designer to implement port-status reporting and configurable hub behavior without relying on a separate controller for every peripheral. The 3.15 V minimum operating voltage provides margin for a regulated 3.3 V system rail, while the industrial temperature grade supports equipment intended for extended environmental duty. The device uses a 56-pin QFN package with an exposed pad and a 0.5 mm lead pitch. Its compact 8 mm by 8 mm footprint is designed for high-density USB hub implementations, but the exposed pad requires deliberate thermal-plane construction and careful control of return-current paths. USB differential pairs should be routed as controlled-impedance interconnects, with the upstream and downstream connections following the layout guidance in the manufacturer datasheet. Typical uses include four-port USB 2.0 docking stations, desktop monitor hubs, external storage enclosures, industrial interface panels, and embedded USB expansion systems. GPIO-driven status LEDs can indicate port activity, connection, or fault conditions, while EEPROM support can retain configuration information when the system design requires nonvolatile hub data. The primary design trade-off is functional integration versus board complexity. The controller consolidates hub traffic management, port indication, GPIO, and EEPROM support into one device, but the 56-QFN footprint demands careful fanout, decoupling, and USB trace routing. Confirm the complete pin assignments, exposed-pad connection, crystal or clock requirements, and power sequencing directly from the manufacturer pin-description table before release. This page organizes the controller’s principal specifications, application guidance, validated ordering alternatives, and PCB considerations into one engineering-focused reference. It also distinguishes confirmed drop-in replacements from ordering and temperature-grade variants so that board compatibility is not inferred from a superficial similarity.

A USB hub controller is an interface IC that manages traffic between one upstream USB host connection and multiple downstream USB ports. Within the hierarchy of USB interface controllers, hub controllers, USB interface ICs, and semiconductors, this device provides port expansion, transaction translation, enumeration support, and power-distribution coordination for USB 2.0 systems. The controller supports up to four downstream ports and USB 2.0 operation. It can operate in either bus-powered or self-powered modes, allowing the same controller family to address systems with different source-current requirements. Its single-translator architecture is identified by Infineon as suitable for ultralow-power applications, while the verified listing describes the family as a low-power USB 2.0 hub controller. The verified product material also identifies an automotive and industrial-grade option rated to 85 °C. This qualification statement applies to the described family or option, but no specific AEC-Q100 certification was supplied, so automotive qualification remains unconfirmed.

CY7C65631-56LTXIT - 4-Port USB 2.0 Hub Controller, 480 Mb/s, 56-QFN

The Infineon (Cypress Semiconductor) CY7C65631-56LTXIT is a low-power EZ-USB HX2LP Lite USB 2.0 hub controller with four downstream ports, 480 Mb/s high-speed operation and a single transaction translator, packaged in a 56-pin QFN (8x8 mm) surface-mount package. A USB hub controller is a dedicated interface IC that sits between a USB host and multiple USB peripherals, managing enumeration, power distribution and transaction translation across a shared USB 2.0 bus. In the power-management hierarchy it sits at the interface tier: USB interface IC -> hub controller -> system connectivity silicon. The EZ-USB HX2LP family was designed for ultra-low-power applications where each downstream port must share a single transaction translator to minimize both silicon area and operating current. Key features of this device include four downstream ports on one shared transaction translator, full-speed and high-speed (480 Mb/s) USB 2.0 operation, 3.3 V single-supply operation with about 163 mA of operating supply current, and an industrial temperature range of -40 C to +85 C. The controller supports downstream port overcurrent detection and enumeration of standard USB peripherals without requiring an external hub PHY. The CY7C65631 is built on a CMOS process, and the datasheet states explicitly that it is pin-for-pin compatible with the CY7C65640 hub controller, which makes footprint planning straightforward across two related USB hub designs. A sibling variant, the CY7C65621, shares the same HX2LP family and 56-QFN footprint but targets different port counts. Typical applications include multi-port USB hubs, laptop and desktop docking stations, set-top box and smart-TV connectivity, industrial human-machine interface panels, USB expansion cards for test and measurement equipment, and automotive infotainment accessories. The main design consideration is power: because all four downstream ports share one transaction translator, hub current stays low, but the 3.3 V rail must still be sized for the worst-case combination of enabled ports and attached peripherals. Decoupling close to the QFN pads and careful D+/D- routing are equally important, since this controller must deliver clean 480 Mb/s signalling over short board-level traces. This page consolidates ordering variants, pin-compatibility notes between the CY7C65621, CY7C65631 and CY7C65640 devices, drop-in alternatives and practical PCB design guidance that engineers would otherwise have to piece together from separate datasheets and cross-reference listings.

The Infineon CY7C65632-28LTXC is a very-low-power USB 2.0 hub controller supporting up to four downstream ports and configured as a single-TT four-port hub. It operates from a 3.3 V supply and is packaged in a 28-pin QFP bulk package with a C-grade temperature designation. The device is intended for compact USB connectivity equipment where an upstream USB port is expanded into multiple downstream ports. A USB hub controller is a system-level interface semiconductor that manages USB traffic, port power, enumeration, and device attachment across multiple USB ports. Within the product hierarchy, this controller belongs to the USB interface controller family, which is part of interface integrated circuits and broader semiconductor connectivity solutions. Unlike a passive USB splitter, an active hub controller can manage four downstream ports, provide port-status control, and support configuration through GPIOs or EEPROM. The verified feature set includes integrated upstream and downstream termination resistors, integrated port-status indicator control, a 24 MHz external crystal with an integrated PLL, and in-system EEPROM programming. These functions reduce external support circuitry and simplify implementation of a bus-powered or self-powered USB hub. The single-TT topology also gives designers a defined method for sharing a USB high-speed path among attached devices. The controller belongs to the EZ-USB HX2VL family and is identified by the Infineon product page as a four-port, single-TT, GPIO- and EEPROM-configurable hub controller. The verified operating-temperature range is 0°C to 70°C, identifying it as a commercial-temperature C-grade option rather than an industrial- or automotive-temperature device. Typical uses include USB connection hubs, docking stations, peripheral-sharing equipment, card readers, printers, and embedded USB expansion products. Designers should pay particular attention to power-enumeration requirements, downstream-port current limits, USB high-speed routing, crystal timing, and the fact that the C-grade part is limited to 0°C to 70°C. The key design consideration is that correct USB hub operation depends on the complete power and signal system, not only the controller IC. Provide the required bypass capacitors, correctly route high-speed differential pairs, maintain compliant termination and ESD protection, and implement the required USB power switching. The target's integrated termination and PLL simplify those blocks, but they do not eliminate validation of the assembled hub against the applicable USB requirements. This page combines the verified Infineon and distributor data with a package-aware comparison, practical implementation guidance, and clearly marked data gaps. It helps engineers separate confirmed specifications from details that must be checked in the manufacturer datasheet before schematic release or PCB layout.

CY7C65632-28LTXCT - USB 2.0 4-Port Hub Controller | Infineon

The Infineon CY7C65632-28LTXCT is a low-power USB 2.0 hub controller from the EZ-USB HX2VL family, supplying up to four downstream ports in a 28-pin QFN package. It is USB 2.0 specification compliant, operates from a single 3.3 V supply, and integrates a single Transaction Translator (TT) for full-/low-speed downstream support, targeted at cost-sensitive hub designs. A USB 2.0 hub controller is a function-specific integrated circuit that aggregates one upstream USB port into multiple downstream USB ports while managing enumeration, power switching, bus enumeration, and transaction translation between the host and connected devices. It belongs to the broader category of USB Interface ICs, within the larger Interface ICs and Integrated Circuits taxonomy. By placing the hub logic and downstream port control on a single die, the HX2VL part eliminates the external TT IC typically required by multi-TT hubs and cuts the BOM for 2- and 4-port hubs. Key features include integrated upstream and downstream USB termination resistors, integrated port-status indicator control (LED drivers), an integrated 24 MHz crystal amplifier, an in-system EEPROM interface for vendor ID / product ID / port-remap customization, and per-port overcurrent detection. The device is configurable via GPIOs to expose 2-port or 4-port topologies and supports both self-powered and bus-powered hub operation. Suspend current consumption is held to a minimum to meet USB 2.0 suspend-current requirements for bus-powered applications. Internally, the HX2VL uses a serial-interface engine for the upstream port and a hub repeater/transaction-translator architecture for the downstream ports, with port-mapping logic driven by the optional external EEPROM. The integrated termination and indicator control reduce PCB area to roughly a 4-layer design with no external PHY, which is the dominant reason designers select this part for compact hub dongles and embedded USB ports. Typical applications include standalone 4-port USB 2.0 hubs for consumer desktops, laptop port replicators, monitors with embedded USB hubs, embedded motherboards, and printer front-panel USB ports. The part is also deployed in industrial USB expansion modules where the GPIO-driven port remapping supports non-standard pin assignments. Designers should keep the 24 MHz crystal or clock source within 5 mm of the XIN/XOUT pins, route the DP/DM differential pairs with 90-ohm differential impedance, and place the upstream port termination near the device pins to preserve USB 2.0 high-speed signal integrity. The optional EEPROM is only required if custom VID/PID or port-disable remapping is needed. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes drawn from the manufacturer datasheet and field experience, in a form that distributors' product pages do not offer.

CY7C65632-48AXC - 4-Port USB 2.0 Hub Controller | Infineon

The Infineon CY7C65632-48AXC is a USB 2.0 hub controller configured as a four-port, single-TT hub, with configurable GPIOs, LED indicators, and EEPROM support. It is supplied in a 48-pin TQFP package with a 7 mm by 7 mm body and a 3.3 V supply requirement. The controller is identified as C-grade in the Infineon product listing. A USB hub controller is an interface IC that manages traffic between one upstream USB host connection and multiple downstream USB ports. In the broader device hierarchy, the CY7C65632 belongs to the USB interface-controller class, then to USB bus controllers and interface ICs, and ultimately to broader semiconductor and connectivity solutions. Its single-TT architecture supports hub communication while programmable port features help connect indicators, controls, or external configuration memory. The verified product listing identifies USB 2.0 operation, four-port Single-TT hub operation, configurable GPIOs, LED-indicator support, EEPROM capability, and a 48-pin TQFP package. A third-party technical listing gives a 3.3 V supply voltage and a 0 to 70 °C operating-temperature range. It also identifies the device as a line and bus controller, while the supplied data confirms a 7 mm by 7 mm TQFP package from the distributor listing. The part is intended for USB hub designs where multiple downstream ports must be coordinated from one upstream connection. Its configurable GPIO and LED functions can be used to report port status or implement user-facing controls, while EEPROM support can assist with configuration storage. The exact pin assignments, electrical limits, timing values, and crystal requirements should be taken from the manufacturer datasheet rather than inferred from distributor summaries. Typical applications include USB 2.0 peripheral hubs, docking stations, desktop connection accessories, embedded USB expansion systems, and equipment that requires multiple downstream USB ports. The single-TT topology and C-grade designation should be matched to the system’s required USB topology, operating-temperature class, and production qualification requirements before release. For PCB design, preserve the controller’s USB data routing, power distribution, clock input, and decoupling requirements from the manufacturer datasheet. Keep high-speed USB traces short and controlled, provide suitable return paths, and verify connector and enclosure decisions against the final hub architecture. Do not substitute a different package or topology solely because its nominal USB function is similar. This page combines the verified manufacturer and distributor identity, exact package information, available commercial references, engineering guidance, and clearly marked data gaps. Distributor pricing, lead time, detailed pinout, and complete lifecycle parameters should be reconfirmed during sourcing and design review.
