Chapter 2. Getting Started
2.1 INTRODUCTION
The Microchip EVB-USB7056 is designed for flexible configuration solutions. It can be
configured via the default internal register settings, via a downloadable external firm -
ware to an on-board SPI Flash, via SMBus, or via the on-board jumper options. When
configured with the default, preloaded SPI Flash firmware, the device operates as a
USB3.1 Gen1 hub with a Type-C upstream port supporting USB PD, one downstream
USB3.1 Gen1 Type-C port, three downstream USB3.1 Gen1 Type-A ports, and two
downstream USB2.0 Type-A ports. The upstream port supports DisplayPort Alternate
Mode and up to 60W of power sourcing to the attached PD-capable host.
Microchip provides a comprehensive software programming tool, MPLAB Connect
(MPLABC), for configuring USB7056 functions, registers, and OTP memory. USB7056
requires MPLABC version 2.1.0 or greater.
For additional information on the MPLABC programming tool, refer to Software Librar

2.2 BOARD CONTENTS
The EVB-USB7056 Evaluation Board includes the basic equipment necessary for eval -
uation. The items included in the board are:
• EVB-USB7056
• ‘PM-PD’ Power Module (premounted to the EVB)
• Type-C-to-Type-C USB cable
2.3 QUICK START
2.3.1 Power Source
A power supply is not included with the EVB-USB7056. Connect a 24V (minimum 75W
is recommended) power supply to the J5 terminal block.
2.3.2 CFG_STRAP1 Jumper
A shunt must be installed on only one of the CFG_STRAP1 options on J9. Any one of
the settings may be selected. Refer to the data sheet for the option that most closely
matches the feature set desired.
2.3.3 Default Firmware
A firmware is loaded by default onto the on-board SPI Flash, and, hence, programming
the SPI Flash before operating the EVB is unnecessary. The D12 LED indicator illumi -
nates bright blue while the hub is executing the firmware from the external SPI Flash.
Note: If it is preferred to run from the internal hub ROM firmware image, install a
shunt on J12 to disable access to the SPI Flash device. PD functionality is
not supported when running the firmware from the internal hub ROM firm -
