USB4624I-1080HN - 4-Port USB 2.0 Hub Controller | Microchip
MPN： USB4624I-1080HN ✓ 啟用中USB4624I-1080HN 概覽
A USB hub controller is an interface integrated circuit that manages transactions between one upstream USB connection and multiple downstream ports. The USB4624 belongs to the USB interface controller hierarchy and uses Multi-Transaction Translator technology to coordinate simultaneous USB traffic. Its USB 2.0 implementation supports full-speed and high-speed operation according to the USB 2.0 Specification and Link Power Management Addendum. This positioning places it above simple four-port USB switches because it also provides device configuration, port management, power-management support, and OEM configurability.
The principal features include four downstream USB ports, HSIC host connectivity, shutdown and low-power operating modes, wake-up support, power-on reset, automatic protocol bridging, and a built-in clock generator. The I-version is associated with an industrial operating-temperature range of -40 degrees C to +85 degrees C. Its 48-SQFN package measures 7.00 mm on each side and has a stated seated height of 1.00 mm, supporting compact PCB layouts in embedded platforms.
The USB4624 is implemented as a CMOS mixed-signal controller that coordinates protocol translation, port-state control, enumeration support, and power management. HSIC is especially useful when the host processor is physically separated from the hub controller because it reduces external data-line exposure compared with conventional USB wiring. The controller can present a Full-Speed-only hub configuration or a combined Full-/Hi-Speed configuration, allowing OEM designs to match downstream-device requirements without changing the controller architecture.
Typical applications include industrial HMIs, USB-to-PCIe embedded systems, medical-device peripherals, set-top and communications equipment, printer interfaces, docking systems, and USB port expanders. A host processor or embedded controller configures the hub through its external control interface, while downstream ports provide protected connectivity for keyboards, storage, cameras, touchscreens, or service interfaces.
Designers should follow the manufacturer reference circuit for HSIC routing, crystal or clock requirements, decoupling, port protection, and downstream-power sequencing. HSIC traces should be routed as a short, impedance-controlled pair on the same PCB layer, with the datasheet-specified resistor and capacitor networks placed close to their associated pins. This page combines the manufacturer specifications with package, application, and replacement guidance to support early architecture and board-layout decisions.

典型應用
USB4624I-1080HN 適用於 6 應用s: Industrial Human-Machine Interface, Embedded USB-to-PCIe Expansion, Medical Equipment Peripheral Hub, Communications and Network Appliance, USB Port Expander and Docking Station, Industrial Data Acquisition System.
Industrial Human-Machine Interface
The USB4624I-1080HN fits an industrial HMI that needs four downstream USB connections for a touchscreen, keyboard, mouse, and service adapter. Its four-port USB 2.0 architecture and HSIC upstream link keep the host processor physically separated from external peripherals, while the stated -40 to +85 degrees C operating range supports temperature-controlled equipment. The 7 x 7 mm SQFN leaves board area for interface protection and power circuitry. Implement the manufacturer reference layout for HSIC routing, decoupling, clock components, and exposed-pad thermal management.
推薦
Embedded USB-to-PCIe Expansion
The USB4624I-1080HN is useful in embedded platforms that require a PCIe host system to expose several USB devices through one internal connection. A downstream-port combination can support storage, cameras, and service peripherals without placing four external connectors directly on the system controller. HSIC provides a compact internal host interface, and the controller's MTT architecture coordinates Full-Speed and Hi-Speed traffic. Layout the HSIC pair and clock network according to the manufacturer reference design to preserve signal integrity.
推薦
Medical Equipment Peripheral Hub
The USB4624I-1080HN can centralize service, diagnostic, keyboard, and storage connections in a medical-equipment enclosure. Its industrial temperature rating of -40 to +85 degrees C supports equipment intended for wider environmental conditions, while the compact 48-SQFN footprint preserves space for isolated power and protection networks. Because medical systems can place strict emphasis on reliability and segregation, designers should follow the USB4624 reference schematic and validate downstream-port protection and power-budget requirements.
推薦
Communications and Network Appliance
The USB4624I-1080HN suits a communications appliance that needs internal USB expansion for storage, diagnostics, or an LTE module. The upstream HSIC connection avoids routing a conventional USB signal across a large motherboard, and four downstream ports support multiple device connections behind one internal interface. The controller's low-power and shutdown modes can assist systems that periodically suspend unused peripherals. Verify current requirements for each downstream port and implement the manufacturer-prescribed power-gating and filtering arrangements.
推薦
USB Port Expander and Docking Station
The USB4624I-1080HN provides the core four-port expansion function for a compact docking station or internal port expander. A system controller can configure the hub while downstream devices such as keyboards, mass-storage media, and diagnostic adapters remain connected through protected ports. Its MTT transaction translator supports coordinated traffic handling, and HSIC provides a practical internal connection to the main processor. Designers should check enumeration behavior, per-port current limits, and connector-protection requirements against the manufacturer documentation.
推薦
Industrial Data Acquisition System
The USB4624I-1080HN fits a data-acquisition system that combines several measurement, storage, and configuration peripherals behind an internal USB link. The stated -40 to +85 degrees C range is useful for industrial enclosures, and the 48-terminal SQFN supports compact controller placement near connector and protection circuitry. The controller can run as a Full-Speed hub for compatible low-speed devices or a Full-/Hi-Speed hub when higher-speed peripherals are attached. Follow the reference layout for HSIC, clocking, and supply decoupling.

設計說明
Implement HSIC as a short, continuous, impedance-controlled pair without layer changes or unnecessary stubs. Place the manufacturer-specified series resistors and support components close to the controller pins, and route the pair away from switching supplies, high-current port-power paths, and crystal oscillator circuitry. A controlled reference-plane arrangement under the pair is important because the internal host-to-hub link carries high-speed differential signaling.
Follow the USB4624 reference schematic for core-supply decoupling, clock support, port-power control, and shutdown connections. Place bypass capacitors at their assigned supply pins with short ground returns, and keep switching-regulator routing away from HSIC and configuration signals. The controller is specified for a nominal 1.2 V supply, so the complete rail tolerance, sequencing relationship, and downstream-port current budget must be validated before release.
Reserve the complete 48-SQFN land pattern, exposed thermal pad, and solder-mask configuration exactly as specified in the manufacturer package drawing. Apply the recommended thermal-via pattern to connect the exposed pad to the appropriate copper area while observing the maximum exposed-pad and trace dimensions. Verify paste, assembly, and rework land patterns separately from the electrical footprint to avoid bridging the fine-pitch 7 x 7 mm package.
