USB2533I-1080AEN - 3-Port USB 2.0 Hub Controller | Microchip
料号： USB2533I-1080AEN ✓ 量产中USB2533I-1080AEN 概述
A USB hub controller is a specialized interface IC that manages traffic between one upstream USB host and multiple downstream USB devices. The USB2533 belongs to the multi-transaction translator, or MTT, controller family within the broader USB interface-controller hierarchy. Its MTT architecture allows multiple USB transactions to be handled efficiently while maintaining compatibility with full-speed and Hi-Speed USB 2.0 devices.
The controller provides three downstream USB ports for embedded host, peripheral, kiosk, medical, industrial, and consumer equipment. Its internal regulator simplifies power-supply design, while programmable signal drive allows the board designer to tune USB data-signal characteristics for the physical layout. Port-power-switch control provides a defined path for managing downstream-port power, and the low-power mode supports energy-conscious designs.
The I suffix identifies the industrial-temperature version, while the -1080AEN ordering code identifies the 36-pin 6 x 6 mm SQFN configuration. The manufacturer describes the USB2533 as fully compliant with the USB 2.0 Specification and USB 2.0 Link Power Management Addendum. It can operate as a full-speed hub or as a full-speed and Hi-Speed hub when connected to a compatible upstream port.
Typical embedded applications include multifunction printers, industrial control panels, point-of-sale terminals, set-top equipment, media appliances, and USB peripheral concentrators. Three downstream ports allow several external peripherals to share one host connection, while BC1.2 support is useful in systems that need to distinguish charging-capable ports from standard USB ports.
PCB implementation requires careful high-speed USB layout, including controlled impedance differential pairs, short matched routing, continuous return-path planning, and careful separation from switching power circuitry. Decoupling and power-distribution networks should be placed close to the supply pins, while the exposed thermal pad and ground connections must be implemented according to the manufacturer package guidance.
This product page combines the manufacturer specifications, package details, practical USB design guidance, sourcing information, and a qualified same-package comparison. It is intended to help engineers assess hub functionality, thermal and layout requirements, and PCB reuse before finalizing an embedded USB design.

典型应用
USB2533I-1080AEN 适用于 6 应用s: Embedded Multifunction Peripheral Hub, Industrial Control Panel, Point-of-Sale Terminal, Medical and Diagnostic Console, Set-Top Media Appliance, USB Charging Port Concentrator.
Embedded Multifunction Peripheral Hub
The USB2533I-1080AEN is suitable for embedded systems that need to expand a single host USB connection into three downstream ports. Its USB 2.0 MTT architecture supports Full-Speed and Hi-Speed operation, while the 3.0 V to 3.6 V operating range fits conventional embedded 3.3 V systems. The internal regulator, port-power-switch control, programmable signal drive, and power-on reset support a compact implementation. Engineers should still budget downstream current, select suitable power switches, preserve controlled-impedance data routing, and verify that every connected device remains within the aggregate USB bus limits.
推荐
Industrial Control Panel
The USB2533I-1080AEN fits industrial control panels that must expose multiple service or peripheral connections to a host controller. Three downstream ports reduce the need for several discrete USB transceivers and hubs, while the industrial-temperature ordering option supports equipment designed for a wider commercial environment. The internal regulator and configurable USB signal drive simplify board integration. In a control cabinet, the design should include ESD protection, robust connector selection, defined power budgets for external devices, and a layout that keeps high-speed USB traces away from noisy switching power stages.
推荐
Point-of-Sale Terminal
A point-of-sale terminal can use the USB2533I-1080AEN to connect several peripherals through one upstream USB connection. The controller provides three downstream USB 2.0 ports with MTT transaction handling, and its BC1.2 support can assist with port-capability and charging-related detection. The 36-pin, 6 x 6 mm SQFN also supports compact board layouts. Product designers should determine whether downstream charging power is managed externally, confirm enumeration requirements for scanners or printers, and test the complete USB power and data path against the system’s peripheral mix.
推荐
Medical and Diagnostic Console
The USB2533I-1080AEN can serve as the USB connectivity hub in a medical or diagnostic console that connects several approved accessories to one host port. Its three USB 2.0 downstream channels, wake-up function, low-power mode, and power-on reset are useful for compact equipment with controlled power states. The industrial-temperature ordering option may suit equipment deployed outside tightly conditioned environments. Medical-system engineers must additionally validate accessory power limits, isolation requirements, USB enumeration behavior, electrical-safety boundaries, and application-specific regulatory procedures.
推荐
Set-Top Media Appliance
The USB2533I-1080AEN is appropriate for a set-top or media appliance that needs multiple USB connections for storage, keyboards, network adapters, or local peripherals. Its MTT hub architecture allows the system to manage multiple USB transactions through a single upstream connection, while the internal regulator and configurable signal drive support compact embedded hardware. The controller’s low-power mode can reduce activity during idle periods. Layout planning should reserve short USB differential routes, suitable return-path geometry, ESD protection at exposed connectors, and power distribution sized for the combination of attached devices.
推荐
USB Charging Port Concentrator
The USB2533I-1080AEN can form the data-controller portion of a multiport USB charging concentrator because it includes BC1.2 support and port-power-switch control. Three downstream ports allow multiple connection opportunities while MTT architecture manages concurrent USB transactions. The controller itself does not define the full external charging-current capability, so designers must select appropriate power switches, power supplies, and protection circuits. Validation should include BC1.2 detection behavior, current limits, thermal performance, short-circuit handling, and compatibility with the connected charging adapters.

设计说明
Route the USB high-speed differential pairs as a controlled-impedance structure with closely matched length and geometry. Keep the traces short, provide a continuous reference plane beneath them, avoid stubs and test pads where possible, and minimize vias. The differential pair should remain separated from noisy switching-node paths and high-current power loops. Check connector placement so no external cable transition introduces abrupt impedance discontinuities.
Design the USB power network around the maximum aggregate load of all three downstream ports rather than one port alone. Use the manufacturer’s recommended input, output, and port-power bypass capacitors and place them close to their associated pins. Confirm the 3.0 V to 3.6 V supply tolerance, external power-switch ratings, and startup current behavior. BC1.2 detection supports port-capability identification, but it does not replace correctly sized power conversion or protection.
Do not substitute the controller solely because the connector shape and port count match. Verify the exact package, pin assignment, configuration requirements, upstream and downstream signal routing, USB specification support, and temperature grade. USB signal drive is programmable, so board-level settings must be coordinated with the selected USB PHY implementation, resistor configuration, cable length, and intended Full-Speed or Hi-Speed operation.
The SQFN must be assembled with its thermal and electrical pad connected to the board according to the manufacturer land pattern. Use an uninterrupted ground or thermal plane where the package guidance permits it, and provide adequate copper area for heat spreading. Thermal performance depends on board size, copper coverage, adjacent heat sources, airflow, and actual controller dissipation, so evaluate the assembled enclosure rather than relying on package dimensions alone.
