It supports low-speed, full-speed, and high-speed downstream devices and uses Multi-Transaction Translator technology for embedded hub implementations. A USB hub controller is an interface IC that expands one upstream USB connection into multiple downstream ports. It belongs to the USB interface controller hierarchy, where USB interface ICs connect host controllers, peripherals, and external devices to the universal serial bus. The USB2513I-AEZG provides the hub-control function needed when an embedded system must expose more USB connections than the host controller offers directly. Key characteristics include USB 2.0 operation, three downstream hub ports, a 3 V to 3.6 V supply range, serial EEPROM configuration support, and a 36-QFN exposed-pad package. The exposed thermal pad supports heat transfer from the controller to the PCB copper, which is important in compact embedded equipment where continuous hub traffic can increase device dissipation. The controller uses Multi-Transaction Translator technology to support multiple transaction types through the embedded USB hub implementation. A serial EEPROM interface allows configuration parameters to be loaded for hub operation. The architecture is intended for systems requiring multiple external USB connections without using a full external host controller at every downstream port.

Microchip Technology USB2514I-HZH is a USB 2.0 high-speed four-port hub controller packaged in a 48-pin VQFN with an exposed pad and supplied in a tray. The verified product information identifies it as a low-speed, full-speed, and high-speed hub controller operating from a 3.3 V supply. Its four-port USB interface architecture makes it relevant to systems that need to expand a single host USB connection across several peripherals while retaining USB 2.0 high-speed support. A USB hub controller is an interface integrated circuit within the broader USB interface-controller hierarchy. It manages traffic between an upstream USB host and multiple downstream USB ports, allowing peripheral devices such as keyboards, storage adapters, communications equipment, and human-interface devices to share one host port. A four-port USB 2.0 implementation is especially relevant to embedded systems, industrial control panels, test benches, and compact peripheral systems that require more attachment points than a host controller exposes directly. The verified product data highlights three defining characteristics: USB 2.0 high-speed operation, four downstream hub ports, and a 48-pin VQFN exposed-pad package. The USB2514I-HZH is also identified as an industrial-temperature-rated part. Microchip describes the related USB251xB family as cost-effective and power-efficient while using MultiTRAK technology to support mixed-speed USB data throughput. These features distinguish it from basic four-port repeater devices by placing port management, signaling, and USB connectivity in one dedicated controller. The part operates from 3.3 V and supports low-speed, full-speed, and high-speed USB devices, allowing a mixed-speed peripheral set to share the same hub. That mixed-speed capability is useful when a design includes legacy USB devices alongside high-speed peripherals. The exposed-pad package also provides a defined thermal and electrical land pattern that must be connected according to the manufacturer layout guidance rather than treated as an unused pin. Typical applications include industrial USB expansion, embedded instrumentation, laboratory data-acquisition systems, USB-to-serial equipment, and peripheral hubs for host computers or embedded controllers. In these systems, the hub can consolidate several external functions behind one upstream USB connection while the controller manages enumeration, downstream port behavior, and data traffic. The USB2422-CP-TR and USB2517I-JZX are related USB interface components available through XAIPART for broader design evaluation. Designers should verify the complete pin assignment, electrical limits, crystal or clock requirements, port-current budget, and exposed-pad connection against the manufacturer datasheet before layout release.

USB2517-JZX - 7-Port USB 2.0 Hi-Speed Hub Controller | Microchip

The Microchip USB2517-JZX is a versatile, cost-effective, and power-efficient 7-port USB 2.0 Hi-Speed hub controller IC in a 64-pin QFN (9x9 mm) package with exposed thermal pad, designed for low-power, small-footprint embedded USB applications. It provides seven downstream USB ports, supports Low-Speed (1.5 Mbps), Full-Speed (12 Mbps), and Hi-Speed (480 Mbps) downstream devices, and operates from a 1.8V/3.3V supply rail. A MultiTRAK™ multi-transaction translator enables concurrent Full-/Low-Speed traffic on multiple downstream ports without bandwidth starvation, and the upstream port supports Hi-Speed operation in accordance with the USB 2.0 specification (April 27, 2000, with 12/7/2000 and 5/28/2002 errata). A USB hub controller is an Interface IC that aggregates multiple USB peripherals behind a single upstream port, presenting each downstream port to the host as an independent device while managing enumeration, power, and transaction translation. Within the broader system hierarchy, the USB2517-JZX sits at Interface IC → USB Controller → USB Hub Controller → USB 2.0 Hi-Speed Hub. Hub controllers are essential building blocks of docking stations, monitors, embedded industrial PCs, and consumer electronics that need to expand a single host USB root port into several usable downstream ports. Key features include per-port or ganged power switching, individual port over-current sensing, integrated 1.5 kΩ upstream pull-up resistor, OTP/serial EEPROM configuration, and support for both bus-powered and self-powered hub topologies. The 64-QFN package with EP provides low thermal resistance and a small 9x9 mm PCB footprint. The device supports SMBus or I²C configuration, complies with USB Battery Charging Specification 1.1 pre-configurations, and integrates an internal 3.3V regulator requiring only a single 3.3V supply or a 5V VBUS-derived rail. The architecture combines a USB 2.0 physical layer (PHY) and a serial interface engine (SIE) per port with a hub repeater and a MultiTRAK transaction translator. This allows multiple Full-/Low-Speed devices to communicate simultaneously with the host at full USB 2.0 bandwidth, eliminating the bandwidth bottleneck found in single-TT hub designs. The hub repeater handles connect/disconnect, suspend/resume, and reset signaling, while per-port PHYs provide signal integrity at 480 Mbps across PCB traces of typical lengths. Typical applications include USB port expansion in monitors, docking stations, industrial PCs, embedded computing, and consumer hubs. It is also used in test equipment, automotive infotainment head units, and any product that must turn one host port into seven USB 2.0 ports. The 1.8V/3.3V flexible supply and small 9x9 mm QFN make it ideal for space-constrained embedded designs. When designing with this part, ensure that the upstream port's 90 Ω differential pair is routed as a length-matched, impedance-controlled USB 2.0 microstrip with a continuous reference ground plane. Place the 480 MHz crystal or oscillator reference as close as possible to the XI pin, and decouple each VDD pin with a 0.1 µF X7R ceramic cap tied to a solid ground pour. A common pitfall is forgetting to populate the upstream series choke or ESD protection array; the hub will enumerate but fail USB-IF compliance without these. This page synthesizes current distributor pricing, same-brand drop-in alternatives from the USB251x family, and practical design notes that go beyond the manufacturer datasheet to help engineers shorten time-to-prototype.

USB2524-ABZJ - USB 2.0 4-Port Switching Hub | Microchip

The Microchip Technology USB2524-ABZJ is a USB 2.0 multi-switch hub controller with two upstream host connections, four downstream ports, and a 56-QFN-EP surface-mount package measuring 8 mm by 8 mm. Its stated operating supply range is 3.0 V to 3.6 V, while USB 2.0 Hi-Speed operation supports 480 Mbps signaling. The controller provides electronic reconfiguration and reassignment of any downstream port to either upstream host on the fly. A USB hub controller is an interface integrated circuit that coordinates communication between one or more USB hosts and attached peripherals. In the broader hierarchy, USB2524-ABZJ belongs to the USB interface controller family, which sits within interface ICs and broader semiconductor devices. Unlike a conventional four-port hub with only one upstream connection, this device combines a Hi-Speed hub with switching logic so two hosts can share the same downstream device set. The USB2524 is identified by Microchip as the industry's first USB switching hub combining USB Hi-Speed hub and switching functions in one device. Its two upstream ports and four downstream ports enable USB device sharing, dynamic host ownership, and reassignment without physically moving equipment. All required resistors on the USB ports are integrated according to the manufacturer data sheet, reducing discrete termination content on the PCB. Operationally, the controller is intended to work with an external USB power-distribution switch device. That external device controls VBUS switching to downstream ports, limits current, and senses over-current conditions. The separation between data-port switching and power-distribution control allows a board designer to use a suitably rated power switch instead of integrating high-current switching entirely inside the 56-QFN controller. Typical uses include shared test benches, industrial peripheral-sharing systems, embedded equipment with multiple USB hosts, kiosk configurations, and automatic test equipment that needs a peripheral to move between hosts. The 3.0 V to 3.6 V supply range suits conventional 3.3 V digital systems, although the complete board must also meet USB signal-integrity, impedance, VBUS, and current-protection requirements. Layout is the principal implementation constraint for this 56-QFN-EP device. Differential USB data pairs require controlled impedance and minimized mismatch, while the exposed pad needs a deliberate thermal and ground strategy. Designers should also follow the manufacturer's USB layout guidance and confirm external power-switch selection, port-current budgets, EEPROM requirements, and all pin functions against the current USB2524 data sheet. This page consolidates the verified manufacturer and distributor information, distinguishes confirmed electrical facts from unspecified parameters, and provides application, sourcing, and design guidance. It also records the absence of a verified pin-to-pin substitute rather than presenting functionally similar or differently packaged USB controllers as drop-in replacements.

USB2601-NU-05 - USB 2.0 Hub Controller | Microchip Technology

The Microchip Technology USB2601-NU-05 is a USB 2.0 high-speed compound interface controller combining a three-port USB hub with a flash media controller, operating from a 3.3 V supply in a 128-lead TQFP package measuring 14 x 14 mm. Its integrated flash controller is permanently assigned to port 1 of the internal USB hub, while the USB 2.0 hub manages upstream and downstream connectivity. A USB hub controller is a specialized interface IC that coordinates data traffic between one upstream host port and multiple downstream peripherals. In the broader semiconductor hierarchy, this USB interface controller belongs to the USB controller family, interface controllers, and power-management and connectivity semiconductor systems. The USB2601 family combines hub and removable-storage functions instead of requiring two unrelated controller ICs. The USB2601-NU-05 supports USB 2.0 high-speed operation and incorporates a flash media controller with FET support. The three downstream USB hub ports make the device useful in compact docks, card readers, printers, media appliances, and embedded systems that need to consolidate external storage and USB peripheral connections. Its 3.3 V operating supply also simplifies integration with contemporary USB host controllers. The 128-TQFP package provides a high pin count for separate USB data, flash-media, power, configuration, and control functions. Surface-mount construction supports automated assembly and compact motherboard layouts. Because the controller contains both high-speed digital interfaces and external media-facing circuitry, board design must preserve controlled impedance routing, solid supply grounding, and short return paths around connector and flash-device connections. Typical applications include multifunction desktop peripherals, USB-connected card readers, portable media docks, embedded data-acquisition equipment, and compact host systems requiring more than one USB port. Integrating the flash controller directly into the hub reduces board-level component count compared with separate hub and storage bridge solutions, provided the selected media interface and supported card formats match the intended product requirements. A key design consideration is the permanent connection of the flash media controller to hub port 1. System architects should therefore treat that port as the dedicated storage path and plan the other two downstream ports for peripherals. Power budgeting, USB enumeration, media-card support, connector data-path routing, and device-capability configuration should be validated together before the PCB is released for production. This product record combines the manufacturer function description, package and supply information, source-linked documentation, application-specific engineering guidance, and a restricted drop-in comparison. It is intended to help engineers identify the correct USB interface controller, distinguish compatible family variants, and plan the surrounding USB and flash-media implementation more efficiently.

The Microchip Technology USB2602-NU-02 is a USB 2.0 compound-device controller that combines a three-port downstream USB hub and a Flash Card Media Controller in a 128-lead TQFP package. Its operating supply range is 3 V to 3.6 V, and the listed -NU-02 ordering code identifies the USB 2.0 interface, Flash Media, four-port hub configuration supplied in a 14 mm by 14 mm TQFP package. The controller is intended to sit between one upstream USB host and downstream USB devices while also supporting Flash media connectivity. A USB hub controller is an interface IC within the broader USB interface-controller and semiconductor hierarchy. It manages port connectivity, power distribution, and data transfer between an upstream host and downstream peripherals. A compound device combines multiple USB functions within one controller, allowing the USB2602 to provide hub and Flash media functionality without requiring a separate hub controller for each function. This integration can reduce board-level component count and simplify enclosure and product design. The USB2602 family supports xD Picture Card format for licensees, as stated by the manufacturer product page. Its USB 2.0 architecture targets host-side accessories, card readers, multifunction peripherals, and embedded USB products requiring a compact hub-and-media-controller solution. The supplied distributor records identify the component as a four-port hub controller and list DigiKey and Mouser as sources for technical data, pricing, and availability. The device operates from a 3 V to 3.6 V supply, allowing use with 3.3 V system rails. Because USB devices impose strict signal-integrity, enumeration, and current-management requirements, board implementation should follow the manufacturer reference design and recommended external-component layouts rather than treating the controller as a generic USB switch. Input and output impedance-controlled traces, short differential connections, solid ground planes, and careful separation between high-current and low-level data paths are particularly important in compact four-port implementations. Typical installations include USB 2.0 card readers, multifunction docking products, removable-media appliances, and compact embedded USB hubs. The integrated hub and Flash media functions are useful where one upstream connection must serve multiple USB peripherals while also reading Flash-based storage. Engineers should confirm host compatibility, supported media formats, electrical characteristics, and enclosure requirements against the current manufacturer documentation before production release. The principal design consideration is validating the complete USB power, firmware, and signal path rather than selecting the IC from headline hub features alone. The 3.3 V supply requirement, upstream and downstream routing, downstream-port current budget, Flash interface implementation, and mechanical package all affect whether the controller is suitable for a given product. This page combines manufacturer function data, distributor availability references, package information, sourcing links, and application-focused engineering guidance. It also distinguishes verified USB2602-NU-02 data from suffix variants whose detailed electrical and pin-level differences are not supplied in the source material, helping engineers make a safer procurement or replacement decision.

The device operates from a 3.3 V supply and is packaged in a surface-mount 128-lead TQFP measuring 14 mm by 14 mm. Its integrated hub and removable-media control make it suited to compact USB connectivity equipment. A USB compound-device controller combines multiple USB functions within one device. In this case, the USB2602 manages the relationship between a single upstream host connection, three downstream USB ports, and supported flash-card media functions. This architecture reduces the number of separate USB interface components required in systems that combine USB expansion with removable storage. The manufacturer identifies the device as a specialized controller interface IC. The primary feature set includes USB 2.0 operation, one upstream connection, three downstream hub ports, and flash-card media-controller capability. The -05 ordering code is associated with a 128-TQFP package, and the 3.3 V operating supply supports integration into conventional consumer and industrial electronics. The USB2602 family also supports xD Picture Card format for licensees using that removable-media format. Technically, the USB2602 belongs to the interface-controller category rather than the general-purpose microcontroller category. Its firmware-specific host interface, hub resources, and media-controller logic provide a consolidated implementation of a multi-function USB peripheral. The 14 mm by 14 mm TQFP footprint offers 128 electrical contacts but requires careful escape routing because its lead pitch makes routed PCB traces more demanding than a fine-pitch BGA. Typical uses include USB card readers, multifunction printers, portable media appliances, industrial data-acquisition equipment, and desktop or docking accessories. The three downstream ports allow several USB peripherals to share one upstream host connection, while the flash-card controller supports removable-storage workflows. The integrated design can simplify system partitioning when product requirements call for both peripheral expansion and card access. Designers should confirm USB routing, transceiver connections, media-format requirements, firmware support, and peripheral load limits against the manufacturer documentation before layout release. Decoupling must be placed close to the supply pins, while high-speed USB traces require controlled impedance, short return paths, careful connector placement, and avoidance of splits across plane boundaries. This product page consolidates the manufacturer-defined USB architecture, package and supply facts, sourcing guidance, application analysis, and engineering checks needed to evaluate the USB2602-NU-05.

For USB2642-I/ML designs, confirm the exact pin functions, electrical limits, reference circuitry, and supported media details against the Microchip datasheet before release. USB high-speed pairs require controlled impedance and careful return-path continuity; card-interface traces should be kept away from noisy switching nodes. The part is not a general-purpose power semiconductor, so a Safe Operating Area chart is not applicable. This page combines the verified manufacturer and distributor information with package, application, procurement, and replacement guidance.

Its integrated design can reduce the need for separate hub and media-reader interface circuitry while supporting both USB expansion and card access. The USB2642/ML is suitable for compact USB hubs, card readers, multifunction peripherals, docking systems, and embedded USB storage products. According to the manufacturer product page, it provides a USB expansion and flash media reader/writer combination in a single chip. The datasheet search results additionally describe sustained flash-media transfer rates exceeding 35 MB/s, although the exact system throughput depends on the attached device and implementation. Designs must follow the manufacturer datasheet for decoupling, USB signal routing, card-interface layout, and exposed-pad thermal management. USB differential pairs should be routed with controlled impedance and minimized discontinuities. The SD/MMC interface and USB connectors should be placed to reduce signal coupling, while the power network should provide low-impedance return paths for both digital and high-current USB loads. This page consolidates the verified manufacturer and distributor information, procurement context, package details, and application guidance for USB2642/ML. It also distinguishes the available same-family Microchip variants without presenting unverified cross-brand replacements as drop-in equivalents.
