USB2504-JT 概述
An integrated USB hub controller is a semiconductor interface device that expands one host USB connection into multiple downstream ports. It sits between a USB host and peripherals, handling port attach, disconnect, enumeration, power-gating, and traffic routing. The USB2504 family is positioned within the USB interface-controller and peripheral-controller hierarchy, providing infrastructure for USB hubs without requiring a separate hub firmware.
Key features include compliance with the USB 2.0 specification, four downstream ports, firmware-free configuration, low-speed, full-speed, and high-speed downstream support, and operation from a 3 V to 3.6 V supply according to the USB2504A-JT comparison data. Configuration can use strapping options, an external EEPROM, or a microcontroller interface; when connected to a microcontroller, the hub appears as an SMBus slave device.
The controller is designed for USB hubs, docking stations, KVM equipment, and embedded systems that need more than one USB port. Its 64-pin TQFP package provides the required external connectivity for four downstream channels and upstream USB signaling. USB 2.0 hub designs must still provide correct power distribution, downstream-port protection, layout routing, and connector implementation; the controller itself does not eliminate those board-level requirements.
A key design consideration is power budgeting. Each enabled downstream port can require current for attached USB devices, so the power supply, switches, protection components, and connector wiring must be sized for the worst-case load. High-speed USB traces also require controlled impedance, short return paths, and careful separation from noisy power and switching circuitry. Microchip documentation provides configuration guidance for EEPROM and microcontroller-based implementations.
This page synthesizes verified manufacturer and distributor information, cross-reference results, package details, and practical engineering considerations. It distinguishes documented USB2504 features from parameters that require confirmation in the manufacturer datasheet, helping engineers evaluate the USB2504-JT for four-port USB hub designs.

典型应用
USB2504-JT 适用于 6 应用s: Four-Port USB Hub, USB Docking Station, KVM Switch, Embedded USB Expansion, Industrial USB Hub, Test and Measurement Hub.
Four-Port USB Hub
USB2504-JT fits a compact USB 2.0 hub because it provides four downstream ports and supports 1.5 Mb/s, 12 Mb/s, and 480 Mb/s link speeds without firmware development. The controller can sit between a host connection and four external USB connectors, reducing the need for a separate hub processor. Board-level design must still allocate downstream power, add port protection, route controlled-impedance USB pairs, and verify the power budget for the selected devices. The no-firmware feature simplifies firmware bring-up, while the 64-pin TQFP package provides the required external hub connectivity.
推荐
USB Docking Station
USB2504-JT is useful in a docking station that needs four USB downstream connections while retaining a compact controller footprint. Its USB 2.0 compliance and support for low-, full-, and high-speed devices allow the hub section to serve keyboards, storage, network adapters, and other peripherals. The controller does not replace dock power management, so the design should calculate aggregate downstream current and use suitable power switches and protection. Controlled-impedance routing and careful connector placement are critical because USB signal integrity affects the 480 Mb/s path.
推荐
KVM Switch
USB2504-JT can form the USB hub section of a KVM switch where multiple downstream devices must share an upstream host connection. Four downstream ports provide a practical expansion point for keyboards, mice, and USB peripherals selected by the switching system. Because the device is a hub controller rather than a full KVM controller, external switching logic may still be required. The board should preserve USB trace geometry across switch paths and account for hot-plug, power-state, and enumeration behavior. Firmware-free operation can simplify implementation when the default configuration is sufficient.
推荐
Embedded USB Expansion
USB2504-JT is suitable for embedded systems that need to expose multiple USB ports from a single host or embedded controller. The firmware-free architecture helps reduce software development for straightforward hubs, while EEPROM or microcontroller configuration provides flexibility when port behavior must be customized. Designers should determine whether the default strapping configuration is sufficient before adding external control hardware. The four-port architecture also simplifies product documentation and connector planning, but each port still needs a defined power budget, protection scheme, and USB-compliant routing strategy.
推荐
Industrial USB Hub
USB2504-JT can support an industrial USB hub when the product requires a dedicated four-port expansion without firmware development. Its USB 2.0 interface and documented speed support are appropriate for service peripherals, data acquisition accessories, and configuration tools. Industrial products may require additional environmental and qualification review, so the operating temperature, EMC, and lifecycle requirements must be confirmed from the manufacturer documentation. The controller should be paired with robust downstream power distribution, fault protection, and connector retention appropriate to the enclosure and use environment.
推荐
Test and Measurement Hub
USB2504-JT can expand a test-and-measurement instrument so several USB peripherals share one host connection. Low-speed and full-speed support is useful for control devices, while high-speed support accommodates storage and higher-bandwidth peripherals. The controller simplifies the USB hub function without firmware development, allowing the instrument designer to focus on measurement safety, data acquisition, and front-panel behavior. The USB subsystem must still be isolated from sensitive analog or high-current sections, and power switching should prevent downstream faults from affecting the instrument.

设计说明
Estimated: size the downstream power system from the maximum simultaneous USB load rather than from the controller supply alone. The verified data establishes four downstream ports but does not provide per-port current limits, fuse ratings, or switch selection. Add the intended device-current budget, allow for inrush and cable losses, select protection components from the final electrical requirements, and verify that the supply, copper paths, connectors, and power switches remain within their ratings during hot-plug events.
Route each USB high-speed differential pair as a short, controlled-impedance pair over a continuous reference plane. Keep the upstream and downstream pairs away from switching power nodes and high-current return paths, and preserve the intended layer-stack geometry from connector to controller. The USB2504-JT can operate at 480 Mb/s, so signal-integrity verification with the assembled PCB is important; controller compliance alone does not validate connector placement, vias, return paths, or cable behavior.
Do not assume that a four-port hub controller automatically supplies four safe USB ports. The board still needs defined downstream power states, protection, connector wiring, and fault behavior. Confirm whether strapping is sufficient or whether an EEPROM or microcontroller is required. Also verify the exact USB2504-JT electrical limits and pin functions in the manufacturer datasheet before assigning a substitute; the supplied comparison establishes package compatibility for USB2504A-JT but not every internal rating.
