USB2517I-JZX-TR 概述
A USB hub controller is an interface semiconductor that manages traffic between one upstream USB host and multiple downstream devices. It belongs to the USB interface controller, interface IC, and connectivity semiconductor hierarchy. The USB2517 family uses MultiTRAK technology to support mixed-speed USB environments while helping embedded designs consolidate multiple peripheral connections behind one upstream host interface.
The USB2517I is identified in the verified data as the industrial-temperature-rated member of the USB2517 family. Its 64-QFN 9 x 9 mm package supports compact embedded implementations, while the integrated hub function reduces the need for discrete USB routing and control components. The device is described by Microchip as low power and OEM configurable, making it suitable for system-level USB port expansion where firmware, hub configuration, and downstream-port requirements are controlled by the OEM.
Typical embedded uses include industrial equipment, test systems, printers, storage appliances, communications equipment, and other products that need more USB connections than a host controller provides directly. Because USB2517I is a hub rather than a host controller, the system still requires an upstream USB host or host-capable controller. The hub’s downstream devices can include low-speed, full-speed, and hi-speed USB peripherals, subject to the operating mode and system configuration.
Designers should verify the complete pinout, power requirements, crystal or clock implementation, port-enable behavior, and configuration requirements against the manufacturer datasheet before layout. The 64-QFN package also requires careful exposed-pad thermal and assembly planning. This page combines verified manufacturer, distributor, and datasheet information with practical design context; unsupported electrical details remain marked for data completion rather than inferred.

典型应用
USB2517I-JZX-TR 适用于 6 应用s: Industrial Test Equipment, Embedded Measurement Systems, USB Storage and Peripheral Hub, Communications and Network Appliances, Printer and Peripheral Expansion, Automotive Infotainment and Cabin Connectivity.
Industrial Test Equipment
USB2517I-JZX-TR fits industrial test equipment that needs to expose several measurement peripherals through one upstream USB connection. Its seven downstream ports allow low-speed, full-speed, and hi-speed devices to share the host interface when the hub operates in hi-speed mode. The 3 V to 3.6 V supply requirement and 64-QFN 9 mm by 9 mm package support compact embedded designs, while the built-in clock generator and power-on reset simplify system integration. Designers should still verify clock configuration, port enables, power budgeting, and the exact 64-pin footprint in the manufacturer datasheet.
推荐
Embedded Measurement Systems
USB2517I-JZX-TR is suitable for embedded measurement systems that connect multiple USB instruments or data-acquisition peripherals to one host. Its seven-port USB 2.0 hub architecture consolidates downstream connections without requiring seven independent host ports. Mixed-speed support helps accommodate legacy full-speed or low-speed peripherals alongside faster devices, provided the upstream link and configuration support the required speeds. The industrial-temperature-rated variant is relevant to equipment operating outside consumer-temperature environments, but the final design must verify power sourcing, enumeration behavior, and cable and connector requirements.
推荐
USB Storage and Peripheral Hub
USB2517I-JZX-TR can serve as the hub controller in storage appliances, printers, and other peripherals that need to present several USB connections to a host. Its seven downstream ports reduce the need for multiple external hub chips in compact equipment, and its low-power mode can help control energy use when ports are not active. The exact USB speed available to each peripheral depends on the upstream connection, hub mode, cable, and device behavior. Power distribution must be designed around the selected downstream devices rather than assuming the controller alone supplies all peripheral power.
推荐
Communications and Network Appliances
USB2517I-JZX-TR is appropriate for communications equipment that adds USB service, configuration, or peripheral ports to an embedded system. A seven-port hub can provide a common interface for maintenance equipment, storage modules, and control peripherals without changing the host controller. The hub controller’s mixed-speed support is useful where older full-speed or low-speed devices coexist with hi-speed peripherals. Firmware must handle enumeration and port configuration, and the PCB layout must preserve USB signal integrity around the 64-QFN footprint and its clock and power connections.
推荐
Printer and Peripheral Expansion
USB2517I-JZX-TR can be used in printers and peripheral products that need more than one downstream USB connection. The hub controller manages one upstream USB connection and exposes seven downstream ports, allowing service tools, storage devices, or status peripherals to share the same physical USB interface. Low-speed and full-speed support helps maintain compatibility with legacy accessories, while hi-speed operation is available when the upstream connection and hub configuration permit it. The implementation must account for connector power, port-enable policy, USB signal routing, and firmware enumeration requirements.
推荐
Automotive Infotainment and Cabin Connectivity
USB2517I-JZX-TR may be evaluated for embedded automotive infotainment or cabin-connectivity systems that need multiple USB peripheral connections. Its industrial-temperature-rated identity, seven downstream ports, and support for Low-Speed, Full-Speed, and Hi-Speed devices make it a candidate for mixed legacy and modern accessory environments. Automotive use requires separate qualification and system-level validation; the supplied data does not confirm AEC-Q100 status. The design must validate operating-temperature limits, power-transient behavior, connector protection, USB signal integrity, and all requirements specific to the vehicle platform.

设计说明
Confirm the complete 3 V to 3.6 V supply requirement, local decoupling, and power sequencing against the manufacturer datasheet. USB downstream devices can draw substantially more current than the hub controller itself, so separate the controller supply budget from connector and downstream-device power design. Check whether the selected hub configuration enables all seven ports before sizing regulators, switches, and protection devices.
Route USB differential pairs as controlled-impedance traces with continuous reference planes, minimizing stubs and unnecessary vias. Keep the hub clock and USB routing away from noisy switching nodes, and follow the manufacturer’s recommended placement and grounding guidance for the 64-QFN device. Validate differential impedance, connector launches, ESD protection, and downstream-port routing with the complete board stack-up.
The USB2517I-JZX-TR uses a 64-QFN 9 mm by 9 mm package, so the land pattern and exposed-pad connection must be taken directly from the official package drawing. Do not copy a generic QFN footprint without checking pad dimensions, pin-one orientation, thermal-pad geometry, and solder mask. Confirm assembly capability, paste volume, and reflow profile before releasing the PCB design.
Do not treat USB2517I-JZX-TR as a USB host controller or assume that the part powers downstream peripherals. A host controller, proper power sourcing, firmware enumeration, and application-specific port policy are still required. Also do not assume every seven-port USB hub IC is pin compatible: verify the complete 64-pin pinout, clock configuration, reset behavior, and package-specific exposed-pad requirements.
合规信息
The supplied verified data confirms industrial-temperature-rated status and USB 2.0 functionality, but does not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. These fields remain unknown rather than inferred.
