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.

1.1INTRODUCTION
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

2.1INTRODUCTION
The Microchip EVB-USB7216 Evaluation Kit is designed for flexible configuration solutions. It can be configured via default internal register settings, via a downloadable
external firmware to an onboard SPI Flash (OTP memory), via SMBus, or via the
onboard configuration switches. When configured with the default internal register settings, the device operates as a USB 3.2 Gen2 hub with one upstream Gen2 port, one
downstream-facing USB Type-C
stream USB 2.0 ports with Microchip’s standard VID/PID/DID settings.
Microchip provides a comprehensive software programming tool, MPLAB® Connect
Configurator (MPLABCC), for configuring USB7216 functions, registers, and OTP
memory. The USB7216 requires MPLABCC version 2.1.0 or greater.
For additional information on the MPLABCC programming tool, refer to Software
Libraries within the Microchip USB7216 product page at

2.2KIT CONTENTS
The EVB-USB7216 Evaluation Kit includes the basic equipment necessary for evaluation. The items included in the kit are:
• EVB-USB7216 Evaluation Board
• Type-A to Type-uB USB cable
2.3QUICK START
Perform the following steps to quickly start using the board:
1. Connect a 12V power supply to the barrel connector (J2) or the terminal block
(J4) on the EVB-USB7216.
2. Using a Type-A-to-Type-uB USB cable, connect the EVB-USB7216 to a USB
host via the upstream “Port 0” USB Type-B socket (J3).
Devices may now be connected to any of the downstream ports to enumerate and use
those devices with the USB host.
To perform additional configuration or evaluate specific features, launch the MPLABCC
software on your USB host or manipulate the included hardware configuration options
detailed in the next sections.

USER’S GUIDE
3.1.1Configuration
3.1.1.1EXTERNAL SPI FLASH
Upon power-up, the USB7216 first looks for an external SPI ROM device and a valid
signature in the Flash. If one is found, the external ROM is enabled, and code execution
is initiated from the external SPI ROM device.
To enable operation from the SPI device, install shunts to pins 1 to 2 and 4 to 5 of J18.
When code is executing from an SPI ROM device, a blue LED “SPI-ACTIVE” (D12) illuminates.
Note 1:CFG_BC and CFG_Non-Rem options are deselected when SPI shunts
are installed on J18. When operating in SPI mode, all configuration is
handled by the code executing from the SPI ROM device.
2:If the SPI Flash is not properly programmed or has an invalid signature,
the USB7216 reverts to internal defaults even if the SPI ROM is selected.
3.1.1.2INTERNAL DEFAULT CONFIGURATIONS WITH STRAPPING OPTIONS
When the USB7216 does not detect a valid SPI Flash image and does not look for
SMBus configuration upon power-up, the USB7216 uses internal default register settings. It also sets the Vendor ID, Product ID, Language ID, and Device ID and additional
settings from the internal ROM code.
If configuration is not done through SPI or SMBus, additional configuration is available
through two functions: CFG_BC_EN and CFG_NON-REM. The controls are configured by selecting one of the six resistor values for each pin. The EVB-USB7216
demonstrates two of the six possible resistor values for each of CFG_BC_EN and
CFG_NON-REM. These straps are sensed by the USB7216 device at power-on to
determine the resultant configuration of the device.
To select the CFG_BC_EN and CFG_NON-REM modes, shunts must be connected to
J16 and J19 headers.
To use the battery charging strap options, connect a shunt to pins 1 to 2 of J8 and connect a shunt to J15 according to Table 3-1. For the NON_REM strap options, connect
a shunt to J19 according to Table 3-2.

J17 Shunt Position(J12 is shunted pins 5-6.)
2–3All ports are non-removable.
1–2All ports are removable.
3.1.2Power Source – Self Powered
The EVB-USB7216 only supports self-powered operation. Power is supplied through
one +12.0V regulated external power supply. The power supply is connected to the
2.5 mm connector J1 on the board. Alternatively, an external voltage can be supplied
to the screw terminal “12V” (J2). The +12.0V feeds a 15A regulator that outputs +5.2V
(nominal) across the board and also supplies the +3.3V regulator and the 1.2V regulator.
CAUTION
The supplied 12.0V external power supply cannot support simultaneous battery
charging on all downstream ports. Use a higher power supply if the required test use
case exceeds the power capability of the supply. Failure to heed to this warning could
result in damage to the 12.0V external power supply.
3.1.3Downstream Port Power Control
USB power to the six downstream ports is controlled via port power controllers with
auto-discharge functionality. All downstream ports support BC 1.2 battery charging.

3.1.4USB Type-C® Ports
The USB7216 has two USB3.2 Gen 2 PHYs for the Type-C port. This eliminates the
need for an external multiplexer. The USB7216 also features integrated Type-C control
signal (CC) detection to determine when and in what orientation a USB Type-C
has been made. It powers only the USB3.2 Gen 2 PHY needed for USB communication. To reduce power, the USB7216 powers down unused USB3.2 Gen 1 PHYs. In
cases where no USB Type-C attach is detected, both USB3.2 Gen 1 PHYs associated
with that port are powered down.
