USB2513B/M2

USB2513B/M2 - 3-Port USB 2.0 Hi-Speed Hub Controller | Microchip

The Microchip Technology USB2513B/M2 is a 3-port, low-power, USB 2.0 Hi-Speed hub controller with integrated MultiTRAK™ multi-transaction translators, housed in a 36-pin SQFN (6x6 mm) package. It supports Low-Speed, Full-Speed, and Hi-Speed downstream devices on a single upstream port, and operates from a single 3.3 V supply with an internal regulator. A USB hub controller is a peripheral device that expands a single USB root port into multiple downstream ports, allowing several USB devices to share one upstream connection. USB hubs sit in the USB 2.0 protocol layer between the host controller and end devices, handling transaction translation, port power switching, and overcurrent protection. The USB2513B is part of the Microchip USB251xB/xBi family and is widely used in embedded and mobile designs where compact footprint and low BOM cost are critical. Key features of the USB2513B/M2 include support for USB 2.0 Hi-Speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) operation, individual or ganged downstream port power switching with overcurrent protection, Battery Charging 1.1 (BC1.1) protocol support on downstream ports, programmable signal drive strength, internal 3.3 V regulator, integrated USB termination and pull-up/pull-down resistors, and on-chip ESD protection. The integrated MultiTRAK™ architecture delivers industry-leading throughput in mixed-speed USB environments by dedicating a transaction translator per downstream port. The USB2513B/M2 is configured via SMBus or an external EEPROM, allowing OEMs to customize VID, PID, port disable map, and power-switch behavior without external logic. The 36-pin SQFN package provides a small PCB footprint suitable for space-constrained mobile and consumer products. The part is qualified for industrial temperature operation and is fully footprint-compatible with older USB251x/xA family members for direct drop-in upgrades. Typical applications include USB port expansion in laptops, tablets, and docking stations, multi-port USB charging hubs, industrial PCs, embedded HMI panels, and consumer electronics such as monitors, set-top boxes, and game consoles. BC1.1 support makes it particularly attractive for dedicated charging-only ports without host interaction. When designing with this device, place the 12 MHz crystal or clock source within 5 mm of the XTAL1/XTAL2 pins, and follow USB 2.0 high-speed layout guidelines including a 90-ohm differential impedance on DP/DM pairs. Decouple VBUS with a 4.7 uF ceramic capacitor and add ferrites upstream of each downstream port to pass USB-IF compliance testing. This page synthesizes distributor pricing, drop-in pin-compatible alternatives, and practical layout notes beyond the manufacturer datasheet to accelerate USB2513B/M2 design-in decisions.

USB2513BT/M2 - USB 2.0 3-Port Hub | Microchip
USB2513BT/M2

USB2513BT/M2 - USB 2.0 3-Port Hub | Microchip

Microchip Technology USB2513BT/M2 is a three-port USB 2.0 hi-speed hub controller operating at 3.3 V in a 36-pin SQFN package with an exposed pad. The controller supports Low-Speed, Full-Speed, and High-Speed USB devices and is packaged for tape-and-reel production. Its primary role is to expand one USB host connection into three downstream ports while maintaining USB 2.0 hub functionality and mixed-speed device support. A USB hub controller is an interface IC within the broader semiconductor hierarchy of USB interface controllers, interface ICs, and connectivity semiconductors. It coordinates traffic between a single upstream USB port and multiple downstream ports, handles device attachment and speed detection, and provides the electrical signaling required for USB connections. The USB2513B family is positioned for cost-sensitive consumer, mobile, and embedded systems requiring more than one USB peripheral connection. The verified product information identifies USB 2.0 Hi-Speed operation, three downstream ports, a 3.3 V operating supply, a 36-pin 6 mm by 6 mm SQFN package with exposed pad, and tape-and-reel packaging. Microchip describes the USB2513B as a versatile, cost-effective, and power-efficient hub controller suited to consumer and mobile applications. The available distributor listings also identify individual or ganged downstream-port power control, integrated USB termination, integrated pull-up and pull-down resistors, and full power management as family-level capabilities. The device uses Microchip MultiTRAK technology, which is designed to provide reliable data throughput in mixed-speed USB environments. Mixed-speed support matters because USB 2.0 hubs can connect peripherals operating at 12 Mbit/s Low-Speed, 1.5 Mbit/s Full-Speed, or 480 Mbit/s High-Speed. Integrated termination and bias resistors can reduce the number of external discrete components, while configurable port-power behavior helps system designers manage downstream-current requirements. Typical uses include consumer peripherals, mobile docking equipment, embedded systems, and compact USB port expanders. A system requiring three USB 2.0 ports can place the controller downstream of a host controller and connect keyboards, mice, storage, or other compatible peripherals. Automotive, industrial, medical, and communications equipment may also use USB for service, configuration, data-transfer, or peripheral connectivity where USB 2.0 compatibility is sufficient. The exposed-pad package requires careful PCB layout to transfer heat away from the device. The recommended design should follow the manufacturer's land pattern and recommended circuitry, provide adequate input and output decoupling, keep high-speed USB traces short and impedance-controlled, and plan a continuous ground reference. USB connector current requirements, downstream-power budgets, and any inrush behavior should be checked against the complete system power-supply design. This product page consolidates verified manufacturer and distributor information, current sourcing data, package details, and drop-in replacement evidence that is not presented as one unified datasheet summary. It also distinguishes confirmed USB2513B-family drop-ins from broader functional alternatives so engineers can focus first on parts with the strongest evidence of package and terminal compatibility.

USB2514B-AEZC - 4-Port USB 2.0 Hi-Speed Hub Controller | Microchip

The Microchip Technology USB2514B-AEZC is a 4-port USB 2.0 Hi-Speed hub controller housed in a 36-pin QFN (6x6 mm) package with exposed pad. It operates from a 3.0V to 3.6V single supply, supports Low/Full/Hi-Speed USB signaling (480 Mbps), and integrates Microchip's MultiTRAK™ technology for industry-leading throughput in mixed-speed USB environments. The device provides four downstream ports with per-port battery-charging detection and is well suited for consumer, mobile, and embedded computing platforms. What is a USB hub controller? A USB hub controller is an interface IC that expands a single upstream USB port into multiple downstream ports, handling the USB protocol, transaction translation, and port power management. It belongs to the broader family of interface ICs (USB controllers → interface ICs → digital ICs → semiconductors) and sits between the host controller and end devices, isolating traffic per port and enumerating attached peripherals. Key features include USB 2.0 Hi-Speed compliance, integrated 1.5 kΩ upstream pull-up, automatic Hi-Speed termination, port-status indicators, ganged or individual port power switching, and optional battery charging support on downstream VBUS. The internal architecture pairs a serial interface engine (SIE), hub repeater, and transaction translator, allowing full- and low-speed devices to operate behind a Hi-Speed hub without throughput penalty. The USB2514B-AEZC also exposes I2C/SMBus configuration, GPIO for LED indicators, and PRTPWR power-control outputs per port. Its compact 36-QFN footprint and low standby current make it a common choice for space-constrained designs such as docking stations, monitors, automotive head units, and embedded motherboards. Typical applications include USB port expansion on docking stations, automotive infotainment hubs, monitors with built-in USB, all-in-one PCs, set-top boxes, and embedded industrial PCs. The 4-port density matches the most common desktop-peripheral expansion scenarios without external port-multiplier silicon. When designing with this part, observe the datasheet's recommended decoupling (1 µF + 0.1 µF near VBAT and VDD33) and provide a stable 3.3V rail. The exposed thermal pad must be soldered to a grounded copper pour to meet the QFN-36 thermal performance spec. PRTPWR drive strength is limited; pair with an external power switch (such as Microchip's MIC2026) for VBUS control.

USB2514B/M2 - 4-Port USB 2.0 Hub Controller | Microchip

The Microchip Technology USB2514B/M2 is a 4-port USB 2.0 Hi-Speed hub controller packaged in a 36-SQFN measuring 6 x 6 mm. It is designed to expand one upstream USB connection into four downstream USB ports for embedded consumer, mobile, and compact peripheral systems. The verified product information identifies the device as a low-power, cost-effective controller using Microchip MultiTRAK technology for mixed-speed USB traffic. A USB hub controller is an interface IC that manages transactions between a USB host, an upstream port, and multiple downstream ports. It belongs to the USB interface-controller hierarchy, combines interface logic and USB connectivity, and is used to add device connectivity without requiring four independent host controllers. USB 2.0 Hi-Speed denotes the 480 Mb/s operating mode, while the four-port configuration consolidates peripheral expansion into a single embedded device. The verified data specifically confirms four USB 2.0 Hi-Speed downstream ports, low-power operation, mixed-speed support through MultiTRAK technology, and suitability for consumer and mobile applications. The controller can reduce external USB switch complexity by integrating hub-management functions into one package. The 36-SQFN footprint also supports compact PCB layouts, although exposed-pad thermal management and careful high-speed routing remain essential. In a typical design, the USB2514B/M2 connects between a USB host and four downstream connectors. Each downstream branch requires appropriate USB data routing and power-path design, while the hub itself needs a suitable reference, clock, decoupling, and configuration implementation defined by the manufacturer datasheet. Because the provided data does not state operating voltage, current, clock frequency, or pin names, those values must be confirmed before schematic sign-off. The USB2514B/M2 is appropriate for docking accessories, compact embedded hubs, mobile accessories, printers, storage peripherals, and consumer equipment where four USB ports are required. Compared with the USB2513B-AEZC family member, its defining advantage is the verified four-port configuration rather than three ports; board compatibility should not be assumed solely from that functional similarity. For implementation, preserve the manufacturer-recommended USB differential impedance, minimize stubs and unnecessary vias, and keep sensitive clock and reference routing away from high-current switching nodes. Verify downstream-port current limits, power-switch selection, enumeration behavior, and thermal performance against the final enclosure and accessory load. This page consolidates verified distributor information, manufacturer product positioning, same-package comparison data, and practical integration guidance. It distinguishes confirmed USB2514B/M2 facts from parameters that require the official datasheet, helping engineers identify the correct hub controller without treating incomplete distributor summaries as complete electrical specifications.

USB2514I-HZH - USB 2.0 HS 4-Port Hub Controller | Microchip

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. The verified distributor information confirms a 48-pin VQFN exposed-pad package and tray packaging, but it does not provide the complete pinout, operating-temperature interval, power dissipation, or recommended external-component values. This product record combines verified manufacturer and distributor information with an explicit comparison of available same-package alternatives, commercial pricing, and application guidance. Missing technical values are marked rather than guessed, allowing engineers to distinguish confirmed USB2514I-HZH characteristics from details that still require direct datasheet verification.

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.

It is designed for embedded USB systems requiring low-power, configurable hub expansion. The controller supports Low-Speed, Full-Speed, and Hi-Speed downstream devices when operating as a Hi-Speed hub, while its upstream attachment can operate as a Full-Speed or Full-/Hi-Speed hub. A USB hub controller is an interface semiconductor that manages traffic between one upstream USB host and multiple downstream devices. It belongs to the USB interface controller, interface IC, and connectivity semiconductor hierarchy. The USB2517 family uses MultiTRAK technology to support mixed-speed USB environments while helping embedded designs consolidate multiple peripheral connections behind one upstream host interface. The USB2517I is identified in the verified data as the industrial-temperature-rated member of the USB2517 family. Its 64-QFN 9 x 9 mm package supports compact embedded implementations, while the integrated hub function reduces the need for discrete USB routing and control components. The device is described by Microchip as low power and OEM configurable, making it suitable for system-level USB port expansion where firmware, hub configuration, and downstream-port requirements are controlled by the OEM. Typical embedded uses include industrial equipment, test systems, printers, storage appliances, communications equipment, and other products that need more USB connections than a host controller provides directly. Because USB2517I is a hub rather than a host controller, the system still requires an upstream USB host or host-capable controller. The hub’s downstream devices can include low-speed, full-speed, and hi-speed USB peripherals, subject to the operating mode and system configuration. Designers should verify the complete pinout, power requirements, crystal or clock implementation, port-enable behavior, and configuration requirements against the manufacturer datasheet before layout.

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

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.

USB2602-NU-02 - USB 2.0 4-Port Hub Controller | Microchip

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.

Typical uses include USB docking stations, compact desktop computers, consumer electronics, card-reader equipment, printers, storage accessories, and embedded USB peripherals. Because the controller consolidates hub and media-card functions, it can reduce the number of separate interface devices required in a compact system. Designers must still account for USB signal routing, connector protection, supply decoupling, card-detect wiring, and the exposed thermal pad when laying out the PCB. 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. It is intended to help engineers identify whether the USB2642-I/ML matches a USB hub plus flash-media architecture before committing the 48-QFN footprint to a PCB layout.

USB2660I-JZX-03 - USB 2.0 Hub & Multi-Format Flash Controller | Microchip

The Microchip Technology USB2660I-JZX-03 is a USB 2.0 Hi-Speed hub controller combined with a multi-format flash media reader/writer and dual Secure Digital (SD) interfaces, integrated in a single chip. Per the Microchip USB2660/USB2660i datasheet (DS00001931B), this combo device delivers up to 480 Mbps Hi-Speed USB performance, two downstream USB 2.0 ports, and multi-format flash card support including SD, MMC, Memory Stick, and xD-Picture Card. The device is housed in a 64-pin QFN (JZX) 9x9 mm package with exposed thermal pad, designed for surface mount desktop and notebook PC applications. The industrial temperature grade (-40C to +85C) makes the USB2660I variant suitable for non-consumer embedded use cases where the commercial-grade USB2660 is insufficient. A USB 2.0 Hi-Speed hub controller is a category of USB peripheral that aggregates multiple downstream ports and card-reader functions behind a single upstream port, while a flash media controller is a class of storage interface IC that bridges a host processor to removable flash memory cards using standardized protocols such as SD, MMC, and MSPro. The USB2660I sits at the intersection of these two product types, forming part of the broader USB interface IC hierarchy: USB peripheral controller -> USB hub controller -> combo hub + media reader -> Microchip USB264x/2660 family. This combination reduces PCB area, BOM count, and design complexity for system integrators that would otherwise need a separate hub chip and card-reader chip. Key features of the USB2660I-JZX-03 include 2 downstream USB 2.0 Hi-Speed ports, an internal transaction translator for mixed-speed USB environments, multi-format flash card support with dual SD interfaces, integrated card power FETs, on-board 24 MHz crystal driver, and USB-IF certified hub silicon. The chip is USB 2.0 compliant and supports Suspend and low-power modes per the USB specification. Programmable through an external I2C EEPROM, the device enables custom vendor/product IDs, string descriptors, and manufacturer-specific behavior. Internally the USB2660I uses Microchip's proven UTMI+ compliant physical layer and a hardened Hi-Speed USB 2.0 hub topology that delivers industry-leading data throughput in mixed-speed environments where some downstream devices run at Full-Speed (12 Mbps) and others at Hi-Speed (480 Mbps). The integrated media controller supports USB Mass Storage class and SDIO bridging, enabling SDIO peripherals to enumerate over USB with custom firmware. Typical applications include desktop and notebook PCs, multi-function printers with card reader slots, docking stations, set-top boxes, and industrial panel PCs that expose SD card slots and multiple USB ports to end users. Designers use the USB2660I-JZX-03 to consolidate USB expansion and media reading onto a single 9x9 mm QFN. When designing with the USB2660I-JZX-03, allocate at least four PCB layers for clean USB signal routing, route the differential DP/DM pair as a 90-ohm impedance-matched pair, and provide a local 0.1 uF decoupling cap adjacent to every power pin. The exposed thermal pad must be soldered to a contiguous ground pour to meet USB-IF Hub Certification thermal-rise limits.

USB3320C-EZK - Hi-Speed USB 2.0 ULPI Transceiver | Microchip
USB3320C-EZK

USB3320C-EZK - Hi-Speed USB 2.0 ULPI Transceiver | Microchip

The Microchip USB3320C-EZK is a highly integrated full-featured Hi-Speed USB 2.0 transceiver built on the proven ULPI (UTMI+ Low Pin Interface) standard, housed in a 32-pin QFN (5x5 mm) package. It supports 480 Mbps High-Speed and 12 Mbps Full-Speed USB signaling, operates from a single 3.3 V supply with on-chip 1.8 V LDO regulator, and provides up to +30 V VBUS ESD protection on the USB connector side. A USB 2.0 transceiver (also called a PHY) is the physical-layer analog block that sits between a digital SoC's ULPI/UTMI link and the differential DP/DM lines of a USB connector. It handles HS chirp, packet detection, serializer/deserializer, and clock recovery, while leaving link-layer protocol to the host controller. Within the system hierarchy, the USB3320C-EZK is a peripheral controller companion IC: SoC (application processor) -> ULPI link -> USB3320 PHY -> DP/DM -> USB connector. This split architecture lets designers pair an inexpensive PHY with any SoC that exposes ULPI pins (NXP i.MX, ST STM32, Xilinx Zynq, TI Sitara). Key electrical characteristics include 480 Mbps Hi-Speed data rate, internal 1.8 V regulator eliminating external LDO, integrated 45 ohm HS termination resistors (no external Rs needed), 8-bit single-data-rate ULPI interface with 60 MHz reference clock, and integrated USB charger-detection hardware. The device is USB 2.0 specification compliant, USB Battery Charging v1.2 capable, and OTG-ready via the ID pin. The architecture uses a 60 MHz reference clock input (REFCLK) generated by the SoC, an internal PLL multiplies to 480 MHz for HS operations. A digital state machine handles UTMI/ULPI command interpretation, while the analog block performs line termination, current-mode driver bias, and disconnect detection. The chip supports both host and peripheral roles. Typical applications include USB 2.0 device/host ports on single-board computers, OTG ports on industrial tablets, automotive infotainment USB interfaces, medical device USB ports, and 5G/LTE modem modules with USB 2.0 diagnostic channels. Designers favor the USB3320C-EZK over UTMI-only PHYs because ULPI slashes pin count to 12 versus UTMI's 30+. When designing with this device, maintain 90-ohm differential impedance on DP/DM traces to the connector, place decoupling capacitors on VDD33/VDD18/VBAT as close as possible to the IC, and ensure the REFCLK signal has less than 50 ps jitter to pass USB compliance. Do not omit the ID pin pull-up for OTG or charger-detection operation.

USB3803 - 3-Port USB 2.0 Hi-Speed Hub Controller | Microchip

The Microchip USB3803 is a three-port USB 2.0 Hi-Speed hub controller optimized for portable, battery-powered embedded systems, integrating BC 1.1 charger detection, flexible internal power regulators, and a 25-ball WLCSP package. It connects to an upstream port as a Full-Speed or Hi-Speed hub and supports Low, Full, and Hi-Speed downstream devices on all enabled ports. The device targets tablets, smartphones, and other mobile platforms where small footprint, low standby current, and minimal BOM are critical design constraints. A USB hub controller is a dedicated interface IC that aggregates multiple downstream USB ports behind a single upstream port, handling transaction translation, port power control, and suspend/resume signaling. In the broader USB-IF taxonomy, hubs sit between hosts (root hubs inside PC chipsets) and peripherals, implementing Chapter 11 of the USB 2.0 specification. The USB3803 belongs to the "embedded hub" sub-category, optimized for integration into battery-powered devices rather than stand-alone retail hubs. Key features include 480 Mbps Hi-Speed upstream support, integrated USB-IF Battery Charging 1.1 detection on the upstream port, integrated 5V-to-3.3V and 1.8V regulators, a serial slave (I2C) interface for status/configuration, and ultra-low standby and bypass current modes. The WLCSP-25 package measures only 2.0 x 2.0 mm, enabling placement on space-constrained mobile mainboards. Microchip's Bypass mode (USB3803C variants) reduces quiescent current to single-digit microamperes when the host is off, directly extending battery life. Architecturally, the USB3803 integrates a Hi-Speed UTMI/ULPI-less PHY, a serial interface engine (SIE), per-port transaction translators, and the charger-detection analog block. The on-chip regulators remove the need for external LDO components when powered from a single 5V VBAT rail, further shrinking BOM count. The I2C serial slave interface exposes charger-status and configuration registers, allowing the application processor to query attach type, port power status, and override default settings. Typical applications include tablets and 2-in-1 laptops requiring one USB-A expansion port, smartphone accessories with OTG-to-host bridging, portable medical devices, and embedded infotainment head units. The charger-detection block also enables the device to act as a charger-sensing front-end, reporting Standard Downstream Port (SDP), Charging Downstream Port (CDP), or Dedicated Charging Port (DCP) classification back to the application processor over I2C. When designing with this part, allocate adequate PCB area under the WLCSP for the exposed die pad and route the 90-ohm differential USB pairs with controlled impedance. Microchip's USBCheck online design review service is available free of charge to qualified customers using the USB3803 in production designs.

The USB5742 specifically implements Microchip's fifth-generation USB 2.0 hub feature controller operating in parallel with a SuperSpeed transaction translator, decoupling 5 Gbps SuperSpeed signalling from legacy 480 Mbps traffic and removing the legacy FS/LS signalling bottleneck of older USB-IF transaction translator rules. Key features include full USB Battery Charging v1.2 support including CDP/DCP modes, integrated 5 V VBUS switch drivers with per-port overcurrent protection, USB Link Power Management (LPM) Addendum compliance for U1/U2/U3 low-power states, role-swapping for reversible Type-C wiring, and Microchip's proprietary Multi-Transaction Translator (Multi-TT) for full 480 Mbps bandwidth on all downstream ports simultaneously. The device operates from a single 3.3 V supply, integrates a 5 V to 3.3 V regulator for internal logic, and the -40C to +85C industrial temperature grade supports embedded OEM use. Typical applications include two-port docking stations, embedded USB expansion for industrial PCs, automotive rear-seat USB chargers, USB Type-A wall chargers with smart-charging, and head-unit infotainment connectivity modules. The SPI host interface allows an external MCU to enumerate attached devices, customize charging profiles, and read port events. When designing with the USB5742/2G, ensure the 56-VQFN exposed pad is properly soldered to a contiguous ground plane of at least 1 square inch to meet the 90 mA unconfigured VBUS-current budget. Bypass the 3.3 V rail with 10 uF + 100 nF ceramic capacitors placed within 5 mm of the supply pin, and follow USB-IF HS/SS routing rules (90-ohm differential impedance, intra-pair skew under 15 ps).

The Microchip USB5807C-I/KD is a 7-port, SuperSpeed USB 3.2 Gen 1 SmartHub IC delivering 5 Gbps downstream bandwidth, housed in a 100-pin VQFN EP (12x12 mm) package with industrial temperature grade (-40C to +85C). It supports USB Type-C with integrated USB-C MUX logic, I2C and SPI management interfaces, and Microchip's MultiTRAK, ProTouch, and PortSwap signal-integrity features. A SmartHub is a USB hub that integrates system-level functions typically performed by a separate MCU or processor. In a typical USB topology, a hub sits between the host (root port) and downstream devices, repeating the differential data and managing power and protocol states. The SmartHub class adds vendor configuration, role-swap (USB-C DRP), GPIOs, and optional firmware-driven behaviors that offload the system processor, which is critical in space-constrained embedded designs. The USB5807C family sits in Microchip's hub-controller hierarchy above the USB251x 2.0-only hubs and below larger 10-port parts like the USB5744. Key features include full USB 3.2 Gen 1 (formerly 3.1 Gen 1 / USB 3.0) 5 Gbps SuperSpeed plus USB 2.0 High-Speed/Full-Speed/Low-Speed backward compatibility on all 7 enabled downstream ports, integrated FlexConnect role-swap, per-port battery charging support (BC1.2), and unique 1.2V/3.3V dual-rail operation that simplifies internal rail generation. Per-port USB-C MUX integration eliminates external crossbar switches, reducing BOM cost and PCB area in USB-C docking designs. Architecturally, the device combines a SuperSpeed USB 3.2 Gen 1 physical layer (PHY), a USB 2.0 PHY, an embedded microcontroller for hub repeater logic, configuration ROM/OTP, and an I2C/SPI slave for host MCU management. The 100-VQFN exposed-pad package provides thermal dissipation suitable for industrial ambient operation without external heatsinking. Typical applications include USB-C docking stations, automotive head-unit USB hubs, thin-client monitors with embedded USB, USB-C monitors, embedded industrial PCs, and any USB-C multiport expansion where role-swap and charging are required. The 12x12 mm VQFN with 0.4 mm pitch is footprint-compatible with the USB5744 family for tier-up/down design reuse. When designing with this device, allocate a 4-layer PCB stack-up to maintain 90 ohm differential impedance for SuperSpeed lanes. Decouple both the 1.2V core and 3.3V I/O rails with 100 nF plus 4.7 uF ceramic capacitors placed within 2 mm of the supply pins. The exposed pad MUST be soldered to a continuous ground plane via a 5x5 thermal via array.

USB5807CT/KD - 7-Port USB 3.2 Gen 1 SmartHub, VQFN-100 | Microchip

The Microchip USB5807CT/KD is a 7-port, SuperSpeed (SS) USB 3.2 Gen 1 SmartHub controller IC delivered in a 100-pin VQFN (12 mm x 12 mm) package with exposed thermal pad. It is USB-IF compliant under TID1595 against the USB 3.2 Gen 1 specification, supports 5 Gbps Super-Speed plus 480 Mbps Hi-Speed, 12 Mbps Full-Speed, and 1.5 Mbps Low-Speed USB signaling, and exposes I2C/SPI host management interfaces for OEM configuration. Operating supply range is 1.08 V to 3.3 V with an operating temperature window of 0 C to +70 C for the commercial CT suffix variant. A USB hub controller is a specialized interface IC that aggregates one upstream USB port into multiple downstream ports while handling the protocol stack, port power management, and traffic scheduling. SmartHubs add OEM-configurable firmware layers (MultiTRAK, flexPORT, PortSplit) on top of the standard hub state machine, enabling per-port behavior tuning, custom charging profiles, and signal-integrity adjustments without external logic. Within the broader IC hierarchy, USB5807CT/KD belongs to Interface ICs > USB Hubs > USB 3.x Hub Controllers > Power-Managed SmartHub family. Key features include 7 downstream ports configurable as USB 3.2 Gen 1 or USB 2.0, native USB Type-C support via integrated MUX logic, MultiTRAK and PortSplit technology for per-port tuning, I2C and SPI host management interfaces, and Broadcom/Microchip-proprietary low-power states with optimized thermal dissipation. The VQFN-100 package provides a compact 12 mm x 12 mm footprint suitable for embedded designs and dock/monitor applications where board area is constrained. The device uses a low-power architecture with embedded USB 3.x PHYs and a configurable hub feature ROM accessed via SPI. PortSplit allows simultaneous USB 3.x and USB 2.0 operation on the same downstream port, enabling embedded USB 3.x peripherals alongside legacy USB 2.0 devices without external muxes. Driver compatibility covers Microsoft Windows 10/8/7/XP, Apple OS X 10.4+, and mainstream Linux hub drivers, removing the need for custom host stacks. Typical applications include USB-C docking stations, multi-port USB hubs, monitors with integrated USB expansion, embedded industrial USB fan-out, and Type-C breakout boards. Choose USB5807CT/KD when a 7-port SS hub with OEM-tunable power/charging profiles is required in a thermally-constrained enclosure. When designing with this part, ensure adequate copper area under the exposed pad and route SuperSpeed pairs with 90 ohm differential impedance. The host MCU must configure PortSplit, flexPORT, and charging parameters via I2C/SPI before downstream ports enumerate at full capability.
