USB2514-AEZG - 4-Port USB 2.0 Hub Controller | Microchip
Référence : USB2514-AEZG ✗ Fin de vieUSB2514-AEZG Présentation
A USB hub controller is an interface IC that manages traffic between one upstream USB port and multiple downstream ports. Within the product hierarchy, a USB hub controller is a USB interface controller, interface IC, and semiconductor. Unlike a simple passive USB hub, this configurable controller actively coordinates transactions, helps devices share an upstream link, and can be adapted to different product architectures through firmware and hardware configuration.
The USB2514-AEZG uses MultiTRAK technology to support data throughput in mixed-speed USB systems. Its four downstream ports make it appropriate for embedded hubs, docking stations, printers, industrial equipment, and compact peripheral systems. The 3.3 V operating requirement supports integration into conventional 3.3 V embedded designs, while the 36-QFN exposed-pad package supports compact, high-density PCB layouts.
Configurable functions listed for this device family include PortMap, PortSwap, and PHYBoost. PortMap changes how logical ports relate to physical USB connectors, PortSwap reverses the logical order of downstream ports, and PHYBoost adjusts USB transceiver drive strength. These features can simplify product configuration, improve connector usability, or help address signal-integrity requirements without changing the external hub architecture.
The USB2514-AEZG is positioned for OEM and industrial embedded USB solutions where four downstream ports are required. Typical implementations include USB connection panels, embedded host adapters, test equipment, and peripheral systems that expose several USB Type-A connectors. Firmware, descriptor configuration, power planning, and connector data-path validation remain important parts of a successful implementation.
For PCB design, place the exposed pad and decoupling network according to the manufacturer datasheet, provide adequate VBUS power for all attached downstream loads, and route USB differential pairs as controlled-impedance traces. Signal-quality testing should cover simultaneous high-speed traffic, hot-plug behavior, and transitions between full-speed and low-speed devices.
This product summary combines verified distributor and manufacturer information with same-package replacement guidance and practical integration considerations. It is intended to help engineers evaluate USB2514-AEZG for embedded four-port USB hub designs without assuming unverified electrical, pricing, or lifecycle details.

Applications typiques
USB2514-AEZG convient pour 6 applications: Embedded USB Docking Hub, Industrial USB Connection Panel, USB Printer and Peripheral Hub, Test and Measurement Hub, Consumer Media and Storage Hub, Legacy USB Port Expansion.
Embedded USB Docking Hub
The USB2514-AEZG fits an embedded four-port USB 2.0 docking hub because it combines one upstream interface, four downstream ports, 3.3 V operation, and MultiTRAK transaction handling in a compact 36-QFN package. A product can expose four USB connectors while retaining configurable PortMap and PortSwap behavior for a consistent user-facing port order. The principal engineering task is allocating VBUS power for all attached loads and preserving USB signal integrity between the controller, connectors, and any external protection devices. The exposed pad must also be connected according to the manufacturer land pattern for electrical and thermal performance.
Recommandé
Industrial USB Connection Panel
For an industrial USB connection panel, the USB2514-AEZG provides a configurable four-downstream-port architecture in a 6 x 6 mm surface-mount package. Its 3.3 V operating requirement and USB 2.0 high-speed upstream interface suit embedded equipment that needs multiple service or peripheral connections without adding four independent host controllers. PortMap and PortSwap can simplify connector assignment, while PHYBoost provides a configurable drive-strength option when signal-integrity testing identifies a need. Designers must still validate the exact operating-temperature grade and environmental requirements for the target industrial enclosure.
Recommandé
USB Printer and Peripheral Hub
The USB2514-AEZG can consolidate printer, storage, and control accessories behind a single upstream USB 2.0 link in an embedded peripheral. Four downstream ports provide room for mixed-speed devices, while MultiTRAK supports transaction handling in environments where full-speed and low-speed devices may coexist with high-speed traffic. Firmware should configure descriptors, port enables, and logical port mapping to match the enclosure layout. Because attached peripherals can have different current demands, VBUS switching and supply design should be tested with the maximum intended load rather than inferred solely from the controller operating voltage of 3.3 V.
Recommandé
Test and Measurement Hub
The USB2514-AEZG is appropriate for a test and measurement instrument that needs several USB connections for probes, adapters, or external modules. A single USB 2.0 upstream connection can feed four downstream ports, reducing host-port requirements and consolidating device enumeration. The controller's configurable port features support repeatable test-system behavior, and the 36-QFN footprint preserves board area in dense instruments. Validation should include enumeration across mixed device speeds, simultaneous high-speed traffic, cable hot-plug behavior, and bus-powered current limits because enumeration performance can be affected by both firmware timing and downstream power availability.
Recommandé
Consumer Media and Storage Hub
A compact media or storage hub can use the USB2514-AEZG to provide four downstream USB 2.0 connections from one upstream port. The controller's small 36-QFN exposed-pad package is useful in space-constrained consumer electronics, and MultiTRAK enables orderly transaction handling when devices operate at different USB speeds. PortMap and PortSwap allow the logical device order to match physical connectors or a preferred product user experience. Firmware must enumerate devices reliably and provide sufficient VBUS current for storage loads, while board layout should minimize stubs and maintain continuous reference-plane support beneath the USB differential pairs.
Recommandé
Legacy USB Port Expansion
The USB2514-AEZG is useful when an embedded computer has too few usable USB ports and the design must preserve an existing USB 2.0 architecture. Adding one upstream connection and four downstream ports can avoid redesigning the host processor and its software stack. Because this is a configurable hub controller, the implementation still requires descriptors, class or vendor drivers as appropriate, and port-management firmware. A migration to USB2514B-AEZG should be considered for a new production release because the supplied data identifies it as the newer generation, whereas the original USB2514-AEZG is most attractive for continuity with an existing board.

Notes de conception
Implement the USB2514-AEZG in a 36-QFN 6 x 6 mm footprint with a properly connected exposed pad. Place the local 3.3 V and I/O decoupling capacitors close to their associated pins, follow the manufacturer land-pattern dimensions, and preserve a continuous ground reference beneath the package. The supplied snippets confirm the exposed-pad package but do not provide the land pattern, so the authoritative package drawing must control pad, solder-mask, and paste geometry.
Route upstream and downstream USB differential pairs as impedance-controlled, tightly coupled traces with minimal stubs and no unnecessary test pads. Keep PHYBoost configuration consistent with connector length, cable type, trace topology, and EMI testing because increasing transceiver drive strength is not a substitute for correct board layout. Validate eye quality and compliance in the completed enclosure, especially when all four downstream ports are active simultaneously.
Design VBUS power independently from the USB2514-AEZG's 3.3 V core supply. Calculate the worst-case demand of all simultaneously enabled downstream devices, include inrush and hot-plug margins, and verify that the supply, switches, protection devices, and connector paths do not cause resets or enumeration failures. The supplied data does not specify the controller's VBUS current rating, so use the manufacturer datasheet rather than assuming that every downstream load can be supplied internally.
Do not treat the -AEZG suffix or the related -TR tape-and-reel listing as proof that every USB2514 variant is interchangeable. USB2514B-AEZG is the strongest documented same-package migration candidate, while USX2064-AEZG-TR is explicitly described as drop-in compatible with USB2514B and may have a different device ID. Confirm pin assignments, clock requirements, firmware, descriptors, VBUS architecture, and qualification requirements before approving a replacement.
Informations de conformité
The supplied verified data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The USB2514-AEZG is described as industrial-temperature rated in one indexed result, but exact temperature limits and qualification documents were not supplied.
