USB2601-NU-05 - USB 2.0 Hub Controller | Microchip Technology
N.º da peça: USB2601-NU-05 ✗ Fim de vidaUSB2601-NU-05 Visão geral
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.

Aplicações típicas
USB2601-NU-05 é adequado para 6 aplicaçãos: Compact USB Card Reader, Multifunction Desktop USB Peripheral, Embedded USB Media Dock, USB Storage and Connectivity Hub, Industrial USB Data Acquisition Unit, USB Networking Gateway.
Compact USB Card Reader
The USB2601-NU-05 fits a compact card reader because it combines a USB 2.0 high-speed interface, a three-port hub, and a flash media controller in one 3.3 V device. The flash controller is permanently connected to port 1, allowing the design to route that path to the appropriate media interface while reserving ports 2 and 3 for external accessories. FET support may assist with the media-facing signal path, subject to the exact interface requirements. This integration reduces the need for separate hub and storage-controller ICs, but the selected card formats, connector arrangement, and downstream-port behavior must be validated against the manufacturer datasheet before layout release.
Recomendado
Multifunction Desktop USB Peripheral
A desktop printer, copier, or media appliance can use the USB2601-NU-05 to combine peripheral connectivity with removable-storage access in a 128-TQFP device. One upstream USB 2.0 connection reaches the host, while the internal hub provides three downstream positions; the dedicated flash controller uses port 1. The 3.3 V operating supply simplifies integration with USB host-side logic, and the high-speed USB 2.0 interface supports throughput-oriented peripheral workflows. Designers should define port roles early, protect each externally accessible connector, and preserve controlled-impedance routing for all USB differential pairs.
Recomendado
Embedded USB Media Dock
The USB2601-NU-05 is appropriate for an embedded USB media dock that needs both storage connectivity and additional peripheral ports. Its three downstream USB hub positions allow a compact enclosure to expose more than one USB interface while the internal flash media controller handles the dedicated storage path. The 14 x 14 mm 128-TQFP package can simplify assembly relative to multiple discrete interface ICs, although its 128-lead layout still requires careful fanout and grounding. Validate removable-media formats, power requirements, connector placement, and firmware enumeration behavior before choosing the controller for an industrial embedded product.
Recomendado
USB Storage and Connectivity Hub
In a USB storage and connectivity hub, the USB2601-NU-05 can provide three downstream positions while dedicating port 1 to its integrated flash media controller. This arrangement is useful where users need one USB connection to a host, removable-media support, and one or two peripheral connections without relying on separate hub and media-bridge devices. The fixed port assignment must be reflected in mechanical connectors and product documentation. Power budgeting is especially important because each downstream port can add load, so validate bus-powered and self-powered operating modes against the manufacturer electrical characteristics before production.
Recomendado
Industrial USB Data Acquisition Unit
The USB2601-NU-05 can support industrial data-acquisition equipment that needs an upstream host connection, multiple service peripherals, and local removable-media logging. Its integrated USB 2.0 high-speed controller and flash path reduce interface-component count, while the 3.3 V operation aligns with modern embedded logic. The controller should be paired with isolation, signal-conditioning, and protection components appropriate to the measured signals rather than treated as a general-purpose data-acquisition front end. Firmware must coordinate enumeration, media access, and concurrent downstream traffic while the PCB maintains uninterrupted USB return paths.
Recomendado
USB Networking Gateway
A USB networking or maintenance gateway can use the USB2601-NU-05 when it requires both an upstream USB link and multiple low-speed peripheral connections alongside local media access. The controller manages one upstream USB 2.0 host port and exposes three downstream positions, with the flash media controller permanently assigned to port 1. Ethernet or other network conversion remains the responsibility of separate interface circuitry. Selection should account for host-driver support, power-source negotiation, media-format requirements, and the possibility that another USB controller offers a more appropriate external connector topology.

- Provides three downstream USB 2.0 positions (vs USB2602-NU-05)
- Uses a common 3.3 V operating supply (vs USB2602-NU-05)
Notas de projeto
Use the manufacturer USB2601/USB2602 land pattern and complete 128-lead pin table rather than a generic 128-pin footprint. Route every USB 2.0 high-speed differential pair with a continuous reference plane, matched spacing, and no intervening split-plane transitions. Place USB connector protection and termination components close to their associated connector or controller pins, and avoid routing high-speed signals beneath noisy media-interface circuitry.
Separate the 3.3 V core rail from externally sourced USB bus power and enforce the applicable USB current limits for each enabled downstream port. Check whether the application is bus-powered, self-powered, or uses a combination of both before assigning connectors. Place local supply decoupling at the controller pins, provide a low-impedance return path under high-speed signals, and verify power-enable sequencing against the manufacturer electrical characteristics and the chosen hub implementation.
Do not treat all three downstream ports as interchangeable. The integrated flash media controller permanently occupies port 1, so the mechanical connector, firmware enumeration model, and user documentation should reflect that assignment. Also avoid selecting USB2602-NU-05 solely by package match: its xD Picture Card support may require licensing and can change the intended product function. Complete a lead-by-lead and software-behavior review before substitution.
