USB2517-JZX

Controllers Overview

The USB2517-JZX is a low-power, OEM-configurable USB 2.0 Hi-Speed 7-Port Hub Controller IC featuring MultiTRAK technology with one transaction translator per port. It supports Full-Speed and Hi-Speed upstream connections while enabling Low-Speed, Full-Speed, and Hi-Speed downstream devices on all seven ports. The device operates within a supply voltage range of 3 V to 3.6 V and draws a typical supply current of 130 mA. It utilizes a 64-pin QFN package (9x9 mm) and supports commercial temperature operation from 0°C to +70°C.

Controllers Feature Summary

• MultiTRAK technology provides dedicated transaction translators for each downstream port to ensure high performance.
• Enhanced OEM configuration options are available through serial I2C EEPROM or SMBus slave port interfaces.
• Integrated power management includes individual or ganged power control and over-current detection for each downstream port.
• On-chip features include an internal 1.8V regulator, USB termination resistors, and a 24 MHz crystal driver.

Controllers Applications

• LCD monitors and TVs
• Multi-function USB peripherals
• PC motherboards
• Set-top boxes, DVD players, DVR/PVR
• Printers and scanners

Controllers Procurement Notes

Verify the specific suffix 'JZX' against official Microchip documentation to confirm it denotes the tape and reel packaging variant rather than tray packaging. Ensure the component meets RoHS compliance standards as specified in the datasheet. Confirm that the commercial temperature grade (-40°C to +85°C industrial option exists but this part is rated 0°C to +70°C) aligns with your system requirements before ordering.

Controllers Selection Notes

Select the USB2517I-JZX if industrial temperature range operation (-40°C to +85°C) is required instead of the commercial range. Consider the EVB-USB2517 evaluation board for initial development and testing of hub configurations. Ensure PCB layout accommodates the 64-pin QFN package dimensions and thermal pad requirements for proper heat dissipation.

Controllers Part Context

The USB2517 series consists of USB 2.0 Hi-Speed 7-Port Hub Controllers designed for embedded solutions. The USB2517 represents the commercial temperature grade variant, while the USB2517I covers the industrial range. Both share identical functional specifications and pinouts, differing primarily in their operational temperature limits and specific ordering suffixes.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Verify compatibility with existing designs by comparing pin assignments and electrical characteristics with alternative hub controllers from other manufacturers if necessary.

Controllers FAQ

How does the USB2517 handle transaction translation?

It uses MultiTRAK technology, which provides one dedicated transaction translator per downstream port, supporting a multi-TT configuration.

What methods are supported for configuring the hub?

Configuration can be performed via an external serial I2C EEPROM, an SMBus slave interface, or by using internal default settings with pin strapping options.

Can the hub operate as both a bus-powered and self-powered device?

Yes, the hub supports both modes. The VBUS_DET pin detects upstream power, and local power availability can be monitored for self-powered applications.
