USB4624-1080HN-TR - USB 2.0 4-Port Hub Controller | Microchip
料号： USB4624-1080HN-TR ✓ 量产中USB4624-1080HN-TR 概述
A USB hub controller is an interface integrated circuit that manages transactions between an upstream USB host and downstream USB devices. It belongs to the USB interface IC hierarchy, which sits between USB connectivity and the larger embedded-control and computer-peripheral markets. The USB4624 is specifically associated with USB 2.0 Hi-Speed operation, low-power embedded implementation, and OEM-configurable hub behavior rather than a general-purpose external desktop hub.
The USB4624 supports four downstream ports and is described by Microchip as an MTT architecture. Its documented low-power behavior, shutdown mode, low-power mode, wake-up function, power-on reset, automatic protocol bridging, and built-in clock generator make it useful for compact embedded systems that need managed USB expansion. These functions allow the hub to fit between a host interface and multiple downstream peripherals while supporting controlled power states and initialization.
The device is associated with the USB 2.0 Specification, the USB 2.0 Link Power Management Addendum, and the High-Speed Inter-Chip USB Electrical Specification Revision 1.0. HSIC is relevant to compact embedded USB designs because the USB4624 family is also referenced with HSIC in the manufacturer data sheet. The electrical design must therefore account for the appropriate USB 2.0 signaling, routing, and implementation requirements described by Microchip.
Typical uses include embedded instrument panels, industrial control equipment, medical monitoring systems, automotive infotainment platforms, set-top boxes, printers, and other products that expose multiple USB connections through an embedded controller. In these applications, the USB4624 can consolidate peripheral connections while giving the OEM control over hub configuration and downstream-port behavior. The 48-SQFN package also supports compact board layouts where connector count is constrained by the enclosure.
The main design consideration is that this controller is a specific USB hub implementation rather than a generic USB interface. Board designers should follow the manufacturer data sheet for the complete pin assignment, power architecture, HSIC implementation, clock requirements, configuration method, and package land pattern. The USB4624I-1080HN-TR is a related variant identified in the component listings, but it should not be assumed to be interchangeable without checking its grade, suffix, and configuration details against the original design requirements.

典型应用
USB4624-1080HN-TR 适用于 6 应用s: Embedded Industrial Control Equipment, Medical Monitoring Systems, Automotive Infotainment Systems, Set-Top Boxes and Media Gateways, Embedded Test and Measurement Instruments, Printers and USB Peripherals.
Embedded Industrial Control Equipment
The USB4624-1080HN-TR fits industrial control equipment that needs several USB peripherals but has limited host-controller ports. Its four downstream ports let one embedded USB connection serve keyboards, memory devices, service interfaces, or data-collection accessories. The low-power and shutdown modes support systems where power management is important, while OEM configurability allows the manufacturer to tailor downstream behavior. A 48-SQFN 7 x 7 mm package also helps preserve PCB area in densely populated control products.
推荐
Medical Monitoring Systems
The USB4624-1080HN-TR can provide a managed four-port USB expansion section in a medical monitoring product. Multiple service, storage, or operator peripherals can connect through a single upstream host link, reducing the need for additional host-controller resources. Low-power operation and shutdown support fit portable and cart-based equipment, while wake-up allows system-level power-state control. The compact 48-SQFN package is useful where front-panel and internal connector placement constrains board area.
推荐
Automotive Infotainment Systems
The USB4624-1080HN-TR is applicable to embedded infotainment systems that need access to multiple USB peripherals through a single upstream connection. The four downstream ports support phone integration, storage, diagnostic accessories, or media interfaces, depending on the complete vehicle design. OEM configurability is useful for tailoring hub behavior to a vehicle platform, and the compact 48-SQFN package assists with constrained PCB layouts. Automotive qualification and electrical requirements must be confirmed separately for the selected production configuration.
推荐
Set-Top Boxes and Media Gateways
A set-top box or media gateway can use the USB4624-1080HN-TR to consolidate several peripherals behind one host connection. Four downstream ports provide room for storage, keyboards, network adapters, service tools, or peripheral controllers without requiring four independent host ports. The USB 2.0 Hi-Speed positioning and OEM-configurable MTT architecture make it relevant to embedded media products, while shutdown and low-power modes help manage unused ports during different operating states.
推荐
Embedded Test and Measurement Instruments
The USB4624-1080HN-TR can expand the USB connectivity of an embedded test instrument that accepts external storage, calibration tools, probes, or service interfaces. Four downstream ports reduce host-side connection complexity, and the power-on reset and wake-up functions support controlled recovery and low-power states. Its 48-SQFN package leaves more board area for analog, processing, or interface circuitry than a larger multi-port arrangement, although signal-integrity layout must follow the manufacturer implementation guidance.
推荐
Printers and USB Peripherals
The USB4624-1080HN-TR is suitable for an embedded printer or peripheral that needs to present multiple downstream USB connections to a host. The ports can serve status displays, local storage, authentication devices, or service interfaces according to the product architecture. OEM configurability supports product-specific downstream behavior, while the built-in clock generator reduces the need for an external clock in designs covered by the manufacturer data sheet. USB signal routing, power, and connector details must be implemented exactly as specified.

关键差异点
- Four downstream ports in a compact 7 x 7 mm package （对比 USB4604-1080HN-TR)

- OEM-configurable MTT implementation （对比 USB4604-1080HN-TR)
设计说明
Use the manufacturer 48-SQFN land pattern and pin-description table when assigning the USB4624-1080HN-TR footprint. Keep HSIC and USB routing away from noisy switching nodes, and place decoupling structures close to their specified device pins. A 7 x 7 mm package leaves little routing room around the perimeter, so footprint and escape-routing review should occur before the component placement and connector locations are frozen.
Design the USB power architecture around the device's specified operating modes and each downstream port's possible current demand. The USB4624 supports shutdown and low-power modes, but those functions do not replace correct rail sequencing, decoupling, and port-power design. Confirm which downstream ports remain powered in each system state and follow the manufacturer data sheet for supply, ground, and exposed-pad requirements.
Treat the upstream and downstream USB connections as controlled-impedance interfaces. Keep HSIC traces short, provide a continuous reference plane, and avoid introducing stubs or unnecessary layer transitions. USB 2.0 Hi-Speed operation requires careful return-path continuity, while the Full-Speed attachment mode should not be assumed to provide the same signaling margin as the Hi-Speed path.
Do not substitute a related USB4624 or USB4604 ordering code solely because the names resemble one another. Verify the exact suffix, configuration method, pin functions, clocking arrangement, supported modes, and required firmware or ROM settings. The USB4624I-1080HN-TR and USB4604-1080HN-TR appear in the verified results, but the available material does not establish complete functional equivalence with USB4624-1080HN-TR.
