Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Information contained in this publication regarding device applications and the like is provided only for your convenience and may be
superseded by updates. It is your responsibility to ensure that your application meets with your specifications. MICROCHIP MAKES NO
REPRESENTATIONS OR WARRANTIES OF ANY KIND WHETHER EXPRESS OR IMPLIED, WRITTEN OR ORAL, STATUTORY OR
OTHERWISE, RELATED TO THE INFORMATION, INCLUDING BUT NOT LIMITED TO ITS CONDITION, QUALITY, PERFORMANCE,
MERCHANTABILITY OR FITNESS FOR PURPOSE. Microchip disclaims all liability arising from this information and its use. Use of Micro-
chip devices in life support and/or safety applications is entirely at the buyer’s risk, and the buyer agrees to defend, indemnify and hold
harmless Microchip from any and all damages, claims, suits, or expenses resulting from such use. No licenses are conveyed, implicitly or
otherwise, under any Microchip intellectual property rights unless otherwise stated.

1.1 INTRODUCTION

The EVB-USB7216 Evaluation Kit is a demonstration and evaluation platform that pro­vides the necessary requirements and interface options for evaluating the USB7216,
which is a six-port Hi-Speed (HS) USB smart hub on a four-layer RoHS-compliant
Printed Circuit Board (PCB). This allows users to gain an understanding of the product
and accelerate the integration of the USB7216 into their designs.

The EVB-USB7216 is compliant with USB 3.2 Gen2 on the upstream port and on down­stream ports 1 to 4. The EVB-USB7216 is also compliant with the USB 2.0 HS,
Full-Speed (FS), and Low-Speed (LS) USB signaling.

The evaluation platform supports six downstream ports: one single Type-C port, four
Gen2 ports, and one USB2.0 port with Type-A connectors. The EVB-USB7216 platform
also supports battery charging on all six downstream ports (maximum of 10A [Note 1]
at any one time). The EVB-USB7216 supports FlexConnect role reversal for any of the
downstream ports with the upstream port.

The EVB-USB7216 has four configurations for operation through internal default set­tings and supports custom configurations through I
SPI Flash device.

The EVB-USB7216 demonstrates driver compatibility with Microsoft Windows
Windows 8.x, Windows 7, Windows XP, Mac OS

For more information about EVB-USB7216, see Section 1.2 “Features”.
