Chapter 1. Overview

1.1 GENERAL INTRODUCTION TO USB7056

The USB7056 hub controller is a six-port SuperSpeed smart hub controller with USB
Power Delivery (PD) support. It is fully compliant with the USB3.1, USB2.0, and USB
PD 3.0 specifications. The six-port hub supports 5 Gbps SuperSpeed (SS USB3.1
Gen1), 480 Mbps High-Speed (HS), 12 Mbps Full-Speed (FS), and 1.5 Mbps
Low-Speed (LS) USB signaling.

The USB7056 has one USB3.1 Gen1 upstream port with PD and DisplayPort
Alternate Mode support. PD support is enabled through a companion PD controller
(UPD350), which operates as a PD PHY + MAC + GPIO expander. The PD firmware
stack executes within the USB7056 hub’s internal microcontroller (MCU). The
DisplayPort Alternate Mode support is enabled through the use of an external 6:4
cross-bar switch. The USB7056 firmware supports up to 100W of power delivery on the
upstream port.

Note: The EVB-USB7056 baseboard supports up to 100W of power delivery by

design. However, the included power regulator is limited to 60W maximum
capability. The default hub firmware load is hence also configured by default
to offer 60W maximum to the device attached to the upstream USB Type-C
PD port. The PD power regulator (abbreviated as PM-PD) is a plug-in daugh­ter card, which can be exchanged to test with various DC/DC solutions. Dif­ferent PM-PD solutions may extend or restrict the maximum power capability
depending upon the capabilities of the individual daughter card, and the hub
firmware load should be reconfigured accordingly when exchanging PM-PD
daughter cards.

The USB7056 has one basic USB3.1 Gen1 downstream USB Type-C port (up to 15W,
no PD), three USB3.1 Gen1 downstream ports, and two USB2.0 downstream Type-A
ports. All downstream ports support battery charging. On these battery charging
enabled downstream ports, the device provides automatic USB data line handshaking.
The handshaking supports USB BC1.2 Charging Downstream Port (CDP), Dedicated
Charging Port (DCP), and legacy devices.

The USB7056 is a smart hub with an embedded MCU for enabling advanced features.
These features include hub configuration through the upstream USB interface,
USB-to-I
bridging, and more.

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 firm­ware 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 Librar­ies within the Microchip USB7056 product page at www.microchip.com/USB7056.

EVALUATION BOARD

USER’S GUIDE

Chapter 2. Getting Started

2.2 BOARD CONTENTS

The EVB-USB7056 Evaluation Board includes the basic equipment necessary for eval­uation. 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 illumi­nates 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-

 2019 Microchip Technology Inc. DS50002887A-page 13

EVB-USB7056 Evaluation Board User’s Guide

ware image. This mode of operation should only be used for debugging or
for loading a new firmware image to the SPI Flash. (The shunt should be
removed right before loading the new firmware image to the SPI Flash.)

2.3.4 Host Connection

A USB2.0 or USB3.1 host must be connected to the upstream Type-C port J2.

If connecting the hub to a Type-A host port, use a USB Type-A-to-Type-C cable. Note
that advanced functionality enabled through USB PD cannot function when using a
Type-A-to-Type-C adapter cable.

If connecting the hub to a Type-C host port, use a USB-IF-certified cable that supports
USB3.1 data protocol to ensure the highest functionality is supported by the cable. If
the host supported Power Delivery and requests power from the EVB-USB7056, the
negotiated voltage can be observed by monitoring the VBUS diode voltmeter on
D25-D28. If the host also supports DisplayPort Alternate Mode, then a display may
optionally connected to the EVB-USB7056 via a DisplayPort cable connected to J31.

Note: Charge-only Type-C cables with missing USB data wires (either missing

USB3.1 wires only or missing both USB2 and USB3.1 wires) do exist.
Always ensure to use USB-IF certified, known good cables when testing with
the EVB-USB7056.

2.3.5 Downstream Port Connections

Once host connection is established on the upstream host port, devices may be con­nected to the downstream ports to begin operating with the USB host. The downstream
port VBUS LEDs may be used to verify that power is properly applied to the down­stream ports. Failure to illuminate indicates either a host connection failure (VBUS is
enabled by the hub only when a command is received from the USB host) or a possible
overcurrent condition on the downstream port.

3.1.1.2 EXTERNAL SPI FLASH

The EVB-USB7056 requires an external firmware image loaded to the on-board SPI
Flash. The external SPI Flash firmware is required to support USB PD functionality. The
EVB-USB7056 is shipped with a firmware image preloaded to the on-board memory.
The firmware revision can be quickly identified by enumerating the EVB-USB7056 to a
USB host PC and inspecting the USB Device ID (bcdDevice) of the USB2.0 or USB3.1
hub.

To properly boot from the SPI Flash, the following conditions must be met:

• Shunts are installed on J15 across pins 1-2 and 4-5.

• Any shunt installed on J12 is removed.

• A valid firmware image is loaded onto the SPI Flash device.

FIGURE 3-2: COMPONENTS CRITICAL FOR EXTERNAL SPI FLASH

FIRMWARE EXECUTION

The recommended sequence for reprogramming the SPI firmware is:

1. Install a shunt onto J12 to force booting from the internal ROM memory.

2. Reset the USB7056.

3. Connect the EVB-USB7056 to a USB host PC with a USB Type-A-to-Type-C

cable.

4. Boot the MPLAB Connect software and select the new firmware image.

5. Remove the shunt on J12.

6. Click the program button on MPLAB Connect.

3.1.1.3 INTERNAL ROM FIRMWARE

A basic hub firmware is included within the USB7056 internal ROM memory that may
be used as a boot-ROM for loading new firmware images into the external SPI Flash.
When the firmware is run from the internal ROM memory, the USB7056 basic hub fea­tures will function, but the USB PD features will be non-functional. A USB
Type-A-to-Type-C adapter cable is recommended when running in this mode to ensure
that the attached host can reliably detect the USB hub and communicate with it.

To force the hub to boot from the internal ROM, install a shunt to J12 as shown in

Figure 3-3. When the firmware is run from the internal ROM memory, the CFG_BC_EN

and CFG_NON_REM configuration straps will also function, and the shunts installed to
J15 should also be moved to short pins 2-3 and 5-6 for these strap configuration
options to be sampled by the hub.

EXECUTION

3.1.1.3.1 BC Strap Select Jumper

A shunt must be installed on only one of the CFG_BC_EN BC1.2 battery charging strap
options on J16. Select J16[1-2] to enable BC1.2 battery charging DCP and CDP on all
downstream ports. Select J16[2-3] to disable BC1.2 battery charging on all down­stream ports.

Note: If a different combination of battery charging enable/disable is desired than

what is available on J16, select J16[2-3] to disable battery charging on all
ports, and then configure the hub via the MPLAB Connect Configurator tool
to enable battery charging support on only the desired subset of downstream
ports.

3.1.1.3.2 Non-Removable Port Strap Select Jumper

A shunt must be installed on only one of the CFG_NON_REM non-removable port
strap options on J18. Select J18[1-2] to set all downstream ports as non-removable.
Select J18[2-3] to set all downstream ports as removable.

Note 1: If unsure with how USB non-removable port option works, it is recom-

mended to select J18[2-3] to set all downstream ports as removable. This
setting is just used as a reporting mechanism to describe the system to the
host; the hub behavior is unchanged by changing this setting.

2: If a different combination of battery charging enable/disable is desired than

what is available on J18, select J18[2-3] to set all downstream ports as
removable, and then configure the hub via the MPLAB Connect Configu­rator tool to set only the desired subset of downstream ports as
non-removable.

3.1.2 Power Source

The EVB-USB7056 must be powered externally through the J1 four-pin DIN connector,
or through the J5 terminal block.

The supported input voltage range for the baseboard is 12V to 24V. By default, the sup­plied PM-PD requires an input of 24V to properly regulate up to 20V to the upstream
PD ports. The recommended input voltage is 24V unless an alternate PM-PD, a spe­cialized hub firmware, or both are used.

A power supply is not included with the EVB-USB7056.

3.1.3 Board Power

The board includes LED indicators to indicate if all board power nets are working and
includes test loops for quick measurements. The location of these LEDs and test loops
are shown in Figure 3-5.

3.1.6 DisplayPort Alternate Mode

The EVB-USB7056 supports DisplayPort (DP) Alternate Mode on the upstream USB
Type-C PD port. The on-board crossboard multiplexer and DP redriver ICs can support
up to DisplayPort v1.3. The following DP Alternate Modes are supported:

• DisplayPort Mode C: 4-Lane DP Alternate Mode (no USB3.1)

• DisplayPort Mode D: 2-Lane DP Alternate Mode with USB3.1 Gen1

The USB host PC that is attached to the upstream Type-C port always determines
which of the DP Alternate Modes (2-Lane or 4-Lane) will be entered. Note that a 4-Lane
DP Alternate Mode uses all four SuperSpeed differential pairs of the Type-C cable and
the USB3.1 Gen 1 connectivity is lost.

The DisplayPort signals are multiplexed and redriven to a standard DisplayPort Source
receptacle. Any DisplayPort monitor display can be attached to the EVB-USB7056 via
this connector. The J31 connector is located on the bottom side of the PCB.

3.1.7 ‘PM-PD’ Plug-in Power Delivery Module

A ‘PM-PD’ module is a PD daughter card that includes a DC/DC regulator that provides
the negotiated voltage to the upstream Port 0 PD port. The modular nature of this
design allows for alternate DC/DC regulators of different architectures or capabilities to
be developed and tested with the USB7056.

By default, the EVB-USB7056 includes a 60W-capable ‘PM-PD’ that is controlled using
GPIOs (one voltage selection pin per voltage) to deliver 5V, 9V, 15V, or 20V at up to 3A.

The EVB-USB7056 design can support a ‘PM-PD’ with up to 100W of power-sourcing

C.

Note: If testing with any ‘PM-PD’ other than the one provided with the

EVB-USB7056 is required, please contact Microchip customer support for
assistance with ensuring that PM-PD technical requirements are satisfied.
Alternate ‘PM-PDs’ may also require customized firmware to operate cor­rectly.
