USB2513I-AEZG - USB 2.0 3-Port Hub Controller | Microchip
부품 번호: USB2513I-AEZG ✓ 활성USB2513I-AEZG 개요
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.
Typical applications include industrial HMIs, point-of-sale terminals, medical-device interfaces, printers, set-top equipment, test systems, and embedded instrumentation. The three-port topology is useful where peripherals such as a keyboard, mouse, storage device, or service interface must share one host USB connection. Product-specific electrical limits, transceiver details, and port-configuration options should be confirmed against the manufacturer datasheet.
For PCB implementation, use the exposed pad as a thermal and electrical connection according to the package land pattern, provide the specified input and output decoupling, and route the USB differential pairs as controlled-impedance nets. Confirm EEPROM, crystal, port-routing, and power-distribution requirements in the reference design before layout release.
This page combines the confirmed USB 2.0, three-port, 3.3 V, and 36-QFN characteristics with package-aware alternatives and practical integration guidance. It is designed to help engineers identify the correct hub controller and plan the associated PCB, configuration, thermal, and signal-integrity work.

일반적인 애플리케이션
USB2513I-AEZG 적합 용도: 6 애플리케이션s: Industrial Human-Machine Interfaces, Point-of-Sale Terminals, Medical-Device Connectivity, USB Printers and Embedded Peripherals, Test and Measurement Equipment, Embedded Set-Top and IoT Gateways.
Industrial Human-Machine Interfaces
The USB2513I-AEZG fits industrial HMIs that need to connect a keyboard, mouse, service interface, and peripheral to one host USB connection. Its three downstream ports expand a single USB link while USB 2.0 low-speed, full-speed, and high-speed support covers common human-interface and data-access devices. The controller operates from 3 V to 3.6 V, allowing implementation on a regulated 3.3 V rail. Place input and output decoupling close to the device, connect the exposed pad to the prescribed thermal and land-pattern structure, and route the USB differential pairs as controlled-impedance nets. Confirm the required port routing and configuration EEPROM contents before schematic release.

Point-of-Sale Terminals
The USB2513I-AEZG is suitable for point-of-sale equipment that combines several peripheral classes with a host processor. A three-port USB 2.0 hub can serve a display interface, input device, printer, scanner, or authentication accessory while retaining a single upstream connection to the host. Supporting low-speed, full-speed, and high-speed devices gives the design flexibility across slow human-interface peripherals and faster storage or printer links. The 3.3 V supply range integrates with common embedded logic rails. Designers should reserve space for the exposed thermal pad, follow the manufacturer's recommended capacitor network and board geometry, and validate enumeration behavior with every intended peripheral combination.
추천
Medical-Device Connectivity
The USB2513I-AEZG can support embedded medical equipment that needs multiple service, data, and user-interface connections without dedicating separate host-controller ports to each accessory. Its USB 2.0 hub architecture accommodates low-speed, full-speed, and high-speed devices while the three downstream ports provide a practical expansion level. The serial EEPROM interface supports device-specific hub configuration. Medical-product engineers should confirm the exact operating-temperature, ESD, lifecycle, and regulatory requirements for the finished equipment rather than inferring them from the controller interface specification. PCB implementation should minimize USB trace-length imbalance and provide a continuous thermal path through the exposed pad.
추천
USB Printers and Embedded Peripherals
The USB2513I-AEZG is appropriate for embedded printers, scanners, and multifunction peripherals that expose several USB device ports through one upstream host connection. The three downstream ports can support service interfaces, removable media, and control accessories, while the hub controller supports USB low-speed, full-speed, and high-speed operation. Because USB 2.0 traffic can vary significantly by peripheral class, designers should evaluate enumeration, suspend, resume, and power-management behavior at the system level. Follow the manufacturer reference schematic for supply decoupling and exposed-pad assembly, and route each enabled downstream connection with the required USB impedance and separation from noisy power paths.
추천
Test and Measurement Equipment
The USB2513I-AEZG is useful in test and measurement instruments where a controller-based host must connect several USB peripherals, service tools, or external adapters. Three downstream ports provide a practical balance between expansion and board complexity, while support for USB 2.0 low-speed, full-speed, and high-speed devices allows mixed peripheral populations. The 3 V to 3.6 V operating range supports standard embedded supply rails. For instrumentation, keep USB data routes away from high-current switching nodes, maintain symmetric geometry for each differential pair, and validate compatibility with the intended USB device classes. The exposed pad should be tied to the manufacturer-prescribed ground and thermal structure.
추천
Embedded Set-Top and IoT Gateways
The USB2513I-AEZG can add USB connectivity to an embedded gateway, set-top box, or IoT edge controller that needs to accept several external USB accessories through one host port. The three downstream ports can support a network adapter, local storage, keyboard, or service connection, and the controller operates over a 3 V to 3.6 V supply range. Compact products should pay particular attention to thermal spreading through the 36-QFN exposed pad and to the area available for USB routing. Use the manufacturer land pattern, preserve recommended copper and via structures, and validate device enumeration across the complete accessory set before releasing the enclosure and board design.

설계 노트
Build the USB traces as a controlled-impedance differential pair and keep their geometry consistent through connectors, vias, and test points. Avoid adding unmatched stubs or changing reference-plane transitions near the controller. Keep the upstream and downstream routes away from switching-regulator switch nodes and high-current return paths. The manufacturer pinout and reference layout should control pad assignment, trace geometry, and via placement.
Treat the exposed pad as part of the device's thermal and electrical design rather than as unused package area. Connect it to the ground structure specified by the manufacturer and provide a short thermal path through vias and PCB copper. Estimated: with a 3.3 V rail and the controller's actual dissipation calculated from the final configuration, temperature rise equals dissipated power multiplied by the effective assembly thermal resistance. Confirm both values before setting copper area.
Decouple the 3.3 V supply close to the controller using the capacitance and placement required by the manufacturer datasheet. Keep the USB transceiver supply distribution compact and isolate switching-converter routing from the hub's sensitive digital connections. Do not infer capacitor values from a generic USB layout; use the manufacturer reference circuit and check the configured downstream-port loading during system power-budget verification.
Do not substitute another member of the USB251x family solely because it uses a VQFN-36 package. Verify downstream-port count, I-family versus B-family behavior, battery-charging requirements, configuration-interface details, and every PCB pin assignment. A package match is necessary for drop-in consideration but does not by itself prove functional or pin-level equivalence.
