USB4604-1080HN - 4-Port USB 2.0 Hub Controller | Microchip
MPN: USB4604-1080HN ✓ نشطUSB4604-1080HN نظرة عامة
A USB hub controller is an interface IC that manages communication between an upstream USB host and multiple downstream devices. It belongs to the USB interface controller hierarchy, where the USB 2.0 controller translates USB traffic while providing device attachment, enumeration, and port-management functions. The USB4604 therefore supports the practical role of expanding one host connection into a managed four-port USB interface.
The controller supports Low-Speed, Full-Speed, and Hi-Speed USB operation as described in the manufacturer documentation. Its four downstream ports can operate as Full-Speed ports, or the device can attach to an upstream Full-Speed port as a Full-Speed hub or to a Hi-Speed upstream port as a Full-Speed or Hi-Speed hub. Operation at 1.8 V and 3.3 V supports integration into embedded equipment using common low-voltage power rails.
The USB4604 uses an MTT architecture and is intended for OEM configuration of embedded USB applications. The manufacturer identifies compliance with the USB 2.0 Specification, the USB 2.0 Link Power Management Addendum, and the High-Speed Inter-Chip electrical specification revision 1.0. This combination of configurable behavior and standards support makes the controller relevant to OEM designs rather than a general-purpose host adapter.
Typical uses include embedded USB hubs, docking systems, industrial equipment, test fixtures, and compact peripheral platforms that need four downstream USB connections. Its small 48-SQFN package also helps limit board area when the design already includes USB connectors, routing space, and required decoupling.
A successful implementation must follow the manufacturer datasheet for HSIC routing, power sequencing, crystal or clock requirements, USB data-path layout, and exposed-pad thermal management. USB differential traces should be routed as controlled-impedance pairs with minimal branch stubs and continuous return paths.
This product page consolidates the manufacturer specifications, commercial availability, family alternatives, and implementation guidance into one engineering-focused reference. It also distinguishes the exact USB4604-1080HN ordering code from related USB4604 family members so designers can verify package, temperature, and configuration requirements before schematic release.

التطبيقات النموذجية
USB4604-1080HN مناسب لـ 6 التطبيقs: Embedded USB Hub, Industrial Data-Acquisition Equipment, Test and Measurement Fixture, USB Docking Station, Embedded Peripheral Gateway, Security and Access-Control Terminal.
Embedded USB Hub
USB4604-1080HN fits an embedded four-port USB hub because it manages one upstream host connection and four downstream ports while supporting USB 2.0 Low-Speed, Full-Speed, and Hi-Speed devices. Its MTT architecture and OEM-configurable design are intended for equipment-specific hub implementations rather than a generic desktop adapter. The 48-SQFN 7 x 7 mm package limits board area, but the layout still needs controlled HSIC traces, local decoupling, an exposed-pad land pattern, and USB connector protection appropriate to the enclosure and cable environment.
موصى به
Industrial Data-Acquisition Equipment
USB4604-1080HN is suitable for compact data-acquisition equipment that needs several instrument, storage, or configuration peripherals connected through one host port. Four downstream ports reduce the need for multiple independent host controllers, while the documented 0°C to 70°C range supports many indoor industrial environments. Firmware must configure the OEM-specific hub behavior, and the enclosure should limit connector-borne ESD and noise. Confirm the complete product's temperature, EMC, isolation, and grounding requirements before deployment.
موصى به
Test and Measurement Fixture
USB4604-1080HN can consolidate several test instruments, programmable power supplies, debug adapters, or storage devices behind a single USB connection in a compact fixture. Its four downstream ports support mixed Low-Speed, Full-Speed, and Hi-Speed devices, allowing one controller to handle different peripheral classes. Use short, impedance-controlled USB routes and provide adequate bus decoupling. For laboratory systems, account for ground loops, ESD at exposed connectors, and host-driver behavior during hot-plug events before finalizing the fixture architecture.
موصى به
USB Docking Station
USB4604-1080HN is appropriate for a compact docking station that turns one host port into four peripheral connections. The controller's MTT architecture and OEM configurability support product-specific attachment and enumeration behavior, while the 48-SQFN footprint leaves board area for connectors, protection devices, and power distribution. Designers should reserve space for downstream-port protection and route HSIC signals according to the manufacturer layout guidance. The system must also enforce USB source-current limits, thermal margins, and connector mechanical requirements.
موصى به
Embedded Peripheral Gateway
USB4604-1080HN can serve as the USB expansion element in an embedded gateway that bridges legacy peripherals to a modern host computer. Four downstream ports allow keyboards, storage devices, service interfaces, and configuration adapters to coexist without requiring multiple host USB controllers. The controller's 1.8 V and 3.3 V operating options can simplify integration with common embedded rails, provided each rail follows the required sequencing and decoupling rules. Software must handle device attach, enumeration, reset, and power-state behavior across all four ports.
موصى به
Security and Access-Control Terminal
USB4604-1080HN can support access-control terminals that need several local USB services, such as a reader, keypad interface, camera, or maintenance connection. Its four-port hub function consolidates these peripherals behind a single internal USB route, reducing host-controller usage in space-constrained equipment. The selected ordering code should be evaluated against the terminal's ambient range and required regulatory environment. In security-focused products, restrict unauthorized USB attachment, validate firmware behavior during hot-plug events, and protect externally accessible ports against ESD and power-fault conditions.

ملاحظات التصميم
Follow the Microchip Technology USB4604 datasheet for HSIC routing, USB data-pair geometry, clock connections, and exposed-pad layout. Keep HSIC and USB differential routes short, continuous, and over a continuous reference plane. Avoid stubs, unnecessary vias, and splits beneath the controller or its clock circuitry. Preserve the manufacturer-specified spacing around signal and power pins because the 48-SQFN footprint provides little room for routing errors.
Implement the 1.8 V and 3.3 V supply networks in accordance with the manufacturer power-supply and decoupling recommendations. Place required bulk and high-frequency capacitors close to their associated pins, minimize loop area, and observe any documented sequencing relationship between rails. Do not assume that USB bus-powered operation permits the same downstream load on every port; verify source-current, device-current, and system power-budget limits.
Treat the 48-SQFN exposed pad as a required thermal and electrical feature. Use the manufacturer land pattern, a solder mask that meets the package drawing, and adequate copper beneath the pad. Estimated: package dissipation depends on the selected core voltage, total bus and digital load, and ambient temperature, so calculate it from the final operating mode rather than relying only on the nominal 1.8 V or 3.3 V supply label.
Do not substitute a USB4604 ordering code solely because the suffix or family name is similar. Confirm package, operating grade, pin functions, configuration values, clock requirements, and exposed-pad treatment. USB4604-1080HN-TR is a tape-and-reel ordering variant rather than a functionally distinct substitute, while USB4604I-1080HN is a separate family ordering code whose exact configuration must be checked before schematic reuse.
