USB2602-NU-02 - USB 2.0 4-Port Hub Controller | Microchip
MPN: USB2602-NU-02 ✗ Cuối đờiUSB2602-NU-02 Tóm tắt
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.

Ứng dụng tiêu biểu
USB2602-NU-02 phù hợp cho 6 Áp dụngs: Four-Port USB Card Reader, Compact USB Docking Station, Multifunction Embedded USB Peripheral, Removable Flash Media Appliance, USB Port Expansion Module, Industrial USB-to-Media Interface.
Four-Port USB Card Reader
The Microchip USB2602-NU-02 fits a four-port USB card-reader architecture because it combines a three-port downstream USB hub with a Flash Card Media Controller in one USB 2.0 compound device. The manufacturer identifies xD Picture Card support for licensees, while the distributor listing describes a USB 2.0 Flash Media four-port hub configuration. A product can therefore present one upstream USB connection to a host while exposing multiple USB ports and Flash-storage access. The controller operates from 3 V to 3.6 V, supporting a 3.3 V system rail. Designers should confirm the exact supported media formats and downstream current budget in the manufacturer documentation because the supplied data does not quantify either value. Layout must also preserve USB signal integrity while routing Flash-media and hub-bus signals through the 128-TQFP device.

Compact USB Docking Station
USB2602-NU-02 is appropriate for a compact dock that needs one upstream USB connection, several downstream peripherals, and Flash-media access without using two unrelated interface controllers. Its one-upstream and three-downstream hub architecture, integrated Flash Card Media Controller, and 3 V to 3.6 V operating range align with a 3.3 V dock platform. Compared with a discrete hub-plus-media-controller arrangement, the compound-device design can reduce board partitioning, although final savings depend on the external components required by each function. The main engineering trade-off is routing complexity: USB differential pairs, media-interface signals, power distribution, and protection components must coexist in a compact board. Follow the Microchip reference layout and validate enumeration behavior across every supported host operating system before release.
Được đề xuất
Multifunction Embedded USB Peripheral
The USB2602-NU-02 can support an embedded multifunction USB peripheral in which a host must access both a hub function and Flash media. Its USB 2.0 compound-device architecture places the hub and Flash Card Media Controller behind one upstream port, simplifying the host-facing connection. The 128-TQFP, 14 mm by 14 mm package is still relatively substantial for a very compact product, so enclosure and connector placement require early review. Because the supplied source information does not provide operating-temperature limits, downstream current ratings, or exact port-power specifications, these must be confirmed before the design is released for industrial or automotive use. Use only the manufacturer’s supported configuration and application guidance when defining descriptors, firmware, and media support.
Được đề xuất
Removable Flash Media Appliance
For a removable Flash media appliance, USB2602-NU-02 provides the USB-facing controller function needed to combine media access with downstream USB connectivity. The manufacturer describes the USB2602 as a compound device supporting one upstream host port, a three-port downstream hub, and a Flash Card Media Controller; the -NU-02 catalog entry identifies the four-port hub version. This makes the part relevant to card readers, media docks, and data-transfer appliances where users expect more than a single USB storage connection. The verified 3 V to 3.6 V supply range simplifies integration with 3.3 V logic, but supported Flash formats, media electrical characteristics, and hot-plug behavior must be verified against the current datasheet. Production testing should also cover insertion, removal, enumeration, and sustained downstream loading.
Được đề xuất
USB Port Expansion Module
USB2602-NU-02 is relevant to a USB port expansion module because one upstream USB connection can feed three downstream hub ports while the same compound controller manages Flash media connectivity. This can simplify a small expansion appliance where separate hub and storage-controller chips would consume additional board area. The 3 V to 3.6 V operating range and 14 mm by 14 mm 128-TQFP package allow integration around conventional 3.3 V power systems, although the large lead count and routed USB and media interfaces demand careful component placement. The design must also account for the power budget of all attached devices rather than the controller’s own supply current alone. Validate connector current ratings, protection, enclosure heat, and cable lengths against the USB 2.0 implementation and manufacturer reference design.
Được đề xuất
Industrial USB-to-Media Interface
For an industrial USB-to-media interface, the USB2602-NU-02 can unify a USB host connection, downstream hub expansion, and Flash-media controller function. The integration may reduce connector-facing circuitry and simplify host software when the compound-device descriptors are properly implemented. Its verified 3 V to 3.6 V operating range suits 3.3 V equipment, but the supplied data does not confirm the industrial temperature range, isolation requirements, surge ratings, or long-term lifecycle status. Those items must be resolved from current Microchip documentation before the controller is used in factory, test, or instrumentation equipment. Engineers should use a protected power input, verify industrial connector and enclosure requirements, and conduct long-duration enumeration, media-insertion, and downstream-load tests.

Ghi chú thiết kế
Implement the USB 2.0 interface using the manufacturer reference layout. Keep upstream and downstream differential pairs short, impedance controlled, and routed over a continuous ground plane; minimize vias and branch stubs, and maintain the separation recommended for USB high-speed signals. Place series termination and required passive components close to the relevant controller or connector pins. Avoid routing these traces beside switching regulators, high-current LED paths, or inductors, and verify the completed board with the USB 2.0 compliance procedure appropriate to the product.
Design the 3 V to 3.6 V supply path around the aggregate downstream load rather than the USB2602-NU-02 core current alone. Use short, low-impedance supply and ground connections, place local bypass capacitors at the controller pins, and separate USB-port power distribution from sensitive logic routing. Verify each connector and power switch against its current rating and the applicable USB power budget. Because exact port-current and thermal data are absent from the supplied records, obtain those limits from the current manufacturer documentation before setting the protection threshold.
Reserve clean, short routing for the Flash Card Media Controller and serial EEPROM interface; excessive capacitance or long stubs can degrade timing and reduce design margin. Place the serial EEPROM close to the associated controller pins and follow the manufacturer’s recommended pull-up and routing arrangement. The 128-TQFP package has a fine pitch, so inspect solder bridging and pad wetting after assembly. Keep media-related and USB differential routing away from antenna, microphone, or high-impedance sensor areas when the target product combines those functions.
Do not substitute a USB2602 suffix solely because the package name is identical. The supplied cross-reference evidence identifies USB2602-NU-05 as a related family candidate, but it does not quantify differences in supported media, configuration, firmware, pin functions, or electrical ratings. Before replacement, compare the manufacturer ordering table and datasheet, then review every affected power, USB, EEPROM, Flash-media, and control connection. Also verify the selected package drawing because the supplied catalog records describe 128-TQFP but do not provide the complete pinout.
