USB20H04-JT-E6 - 4-Port USB 2.0 Hub Controller | Microchip
MPN: USB20H04-JT-E6 ✓ ActiveUSB20H04-JT-E6 Overview
A USB hub controller is an interface integrated circuit that manages traffic between one USB host connection and multiple downstream USB ports. Within the interface IC hierarchy, it connects USB connectivity and system buses such as I2C and SMBus. Its four-port architecture is appropriate for peripherals, embedded computers, industrial equipment, and compact USB expansion systems.
The device provides USB 2.0 connectivity for four downstream ports and exposes I2C, SMBus, and serial interfaces for configuration or system management. The 64-pin TQFP package provides the external connections required for downstream-port routing, upstream USB routing, power management, clocking, and control functions. The USB20H04-JT-E6 suffix identifies a specific ordering configuration associated with the USB20H04-JT device family.
The controller is intended for systems in which one embedded host must connect several USB peripherals. Four downstream ports reduce the need for separate external hub hardware while preserving the common USB 2.0 device model. I2C and SMBus connectivity can support control of attached functions, although the final implementation must follow the pin-description table and reference design in the manufacturer documentation.
Typical uses include industrial HMI panels, USB data-acquisition equipment, printers, service interfaces, external storage, and embedded test systems. The USB20H04-JT-E6 is particularly useful when a baseboard needs more than one USB peripheral connection while conserving space in a high-pin-count surface-mount design.
For implementation, use the manufacturer's USB20H04 reference material to define upstream and downstream routing, power distribution, termination, and decoupling. Review the application note covering migration to USB2504 before changing board layouts because internal-regulator power-pin definitions differ even when PCB compatibility can be accommodated.

Typical Applications
USB20H04-JT-E6 is suitable for 6 applications: Embedded USB Expansion, Industrial HMI Panel, USB Data-Acquisition Equipment, Networked Test and Measurement System, USB Printer and Service Interface Hub, Industrial Gateway with USB Peripherals.
Embedded USB Expansion
The USB20H04-JT-E6 fits an embedded baseboard that needs one upstream USB host connection and four downstream peripheral ports. Its 4-port USB 2.0 hub function consolidates storage, printers, service interfaces, or data loggers without requiring a separate external hub controller. The 64-pin TQFP also provides I2C, SMBus, and serial connectivity for system-level configuration. PCB implementation should follow the manufacturer reference material for upstream and downstream routing, power distribution, termination, and decoupling.
Recommended
Industrial HMI Panel
The USB20H04-JT-E6 is suitable for an industrial human-machine interface that must expose several service or peripheral connections. Four USB 2.0 downstream ports can support removable media, configuration interfaces, diagnostic tools, and local adapters through a single host connection. The integrated I2C and SMBus interfaces can assist board-level management, while the serial interface adds another control path. Confirm operating-temperature limits, EMC performance, and input-power tolerances against the manufacturer documentation for the final industrial installation.
Recommended
USB Data-Acquisition Equipment
The USB20H04-JT-E6 can support laboratory or field data-acquisition equipment that needs to connect several USB peripherals to an embedded controller. Its four USB 2.0 ports can accommodate measurement adapters, mass storage, calibration equipment, and maintenance interfaces. The 64-pin TQFP supports integration on a multilayer PCB, while I2C and SMBus can share bus connectivity with sensors and configuration devices. Designers should account for port-enumeration timing, inrush current, device brownout behavior, and ground-return paths when selecting power and protection components.
Recommended
Networked Test and Measurement System
The USB20H04-JT-E6 fits automated test systems where a controller must connect instruments, storage, and service peripherals. Four USB 2.0 downstream ports reduce external hub requirements and keep peripheral connections standardized. Ethernet and serial-interface components can provide broader equipment connectivity, while I2C and SMBus support configuration and monitoring. Because the USB20H04 is a dedicated hub controller rather than a general-purpose processor, confirm operating-system compatibility, supported device classes, and enumeration behavior for every instrument that will be attached.
Recommended
USB Printer and Service Interface Hub
The USB20H04-JT-E6 is appropriate for embedded systems that must combine a printer, local storage, and service or security interfaces. Four USB 2.0 downstream ports provide a practical expansion path, while the dedicated hub function manages the shared upstream connection. The device can be paired with interface controllers and transceivers for broader system connectivity. Validate cable-length limits, available charging current, per-port power switching, and peripheral sleep behavior because those requirements depend on the complete hub implementation and attached-device power budget.
Recommended
Industrial Gateway with USB Peripherals
The USB20H04-JT-E6 can serve as the USB expansion element in an industrial gateway that bridges embedded processing to local USB equipment. Its four-port USB 2.0 configuration is useful for diagnostic notebooks, removable media, sensors, and configuration adapters. The I2C and SMBus interfaces complement Ethernet-based gateway designs by supporting local sensors and management ICs. For field deployment, verify temperature rating, surge and ESD implementation, regulatory EMC performance, and recovery behavior after a downstream device faults or shorts a port.

Design Notes
Use the manufacturer USB20H04 reference circuit to select the regulator, port-power switches, and decoupling network. When migrating to USB2504-JT, revise the internal-regulator power connections because the application note states that their definitions differ. Check device brownout behavior, per-port current limits, startup order, and the combined load of attached USB peripherals before committing the power architecture.
Route upstream and downstream USB differential pairs as controlled-impedance traces with continuous reference planes and minimize branch stubs. Follow the manufacturer layout for trace length, spacing, ESD protection, and via transitions. The 64-pin TQFP requires careful fan-out around all four ports; review the official package drawing and pin-one orientation before defining the land pattern and assembly documentation.
Treat USB 2.0 connections as high-speed differential links even though the hub operates at USB 2.0 data rates. Keep connector-to-controller routing short, provide a continuous ground reference, and place protection and termination components near their associated connectors. Validate eye quality, common-mode behavior, and enumeration reliability across the intended cable lengths because four downstream ports can create several simultaneous high-speed paths.
Do not assume that an identical TQFP outline guarantees an electrically drop-in replacement. USB2504-JT uses different internal-regulator power-pin definitions, and undocumented suffix differences may affect ordering or assembly. Verify the complete pin list, power connections, package drawing, operating conditions, and peripheral compatibility against manufacturer documentation before approving a substitution.
Compliance Information
The manufacturer product record and USB20H04 datasheet do not establish the requested compliance statements in the cited material. Confirm RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals status against the current manufacturer product documentation before qualification.
