Overview
The Microchip Automotive Grade USB 2.0 4-Port Hub is designed, fabricated, tested, characterized and qualified for automotive applications. The USB82514 MultiTRAK™ is a low-power, OEM configurable, full featured Hi-Speed USB 2.0 compliant hub contnroller IC with four down-stream ports for embedded USB solutions. The EVB-USB82514 36-Pin QFN Evaluation Board demonstrates a stand alone application for the hub with all the features listed below and demonstrates the advanced power saving options and configurable port assignments.
- Low pin count USB82514 36 - pin QFN package
- Hi-Speed (480 Mbits/s), Full-Speed (12 Mbits/s), and Low-Speed (1.5 Mbits/s) compatible
- Operation from a single voltage (+5.0 VDC, regulated) 'wall wart' external power supply
- Low cost 4-layer design: two outer signal layers - power inner layers - ground inner layers
- Optional pull-up resistors for disabling individual downstream ports
- Self-powered operation
- Multi-transaction translator enabled
- Support of internal default hub configuration
- Single onboard +3.3 VDC regulator
- Single crystal clock sourc
- Individual port over-current sensing
- Individual port power control
- Port over-current sensing (OCS)/port power control interface with LEDs for port power indication
- Red LED indicator for active hub state (not suspend)
- EMI suppression provided by ferrite beads, selection of capacitors, and internal power/ground layers.
- ESD protection up to 25 kV direct contact to USB signals provided with diode bridges and common mode chokes.
