1.1 INTRODUCTION

The EVB-USB5744 Revision A is a demonstration and evaluation platform that provides the
necessary requirements and interface options for evaluating the USB5744 Ultra Fast four port
battery charging hub on a 4-layer RoHS-compliant Printed Circuit Board (PCB). This will allow
the user to gain an understanding of the product and accelerate the integration of the
EVB-USB5744 into the user’s design. The EVB-USB5744 is compliant with the USB 3.1 Speci­fication and supports SuperSpeed (SS), High-Speed (HS), Full-Speed (FS), and Low-Speed (LS)
USB signaling for complete coverage of all defined USB operation speeds. The evaluation plat­form supports four downstream ports that are USB 2.0 and USB 3.1 Gen 1 compliant. The
EVB-USB5744 platform also supports battery charging on all four downstream ports (maximum
of 5A at any one time). The EVB-USB5744 is configured for operation through internal default
settings and supports custom configurations through SMBus or through the external 64-Mbit SPI
Flash device, U8. The EVB-USB5744 demonstrates driver compatibility with Microsoft® Win­dows® 8x, Windows 7, Windows XP, Mac OS® X 10.4+, and Linux® hub drivers.

The EVB-USB5744 provides the following features:

• USB5744 in a 56-pin QFN RoHS compliant package

• USB 3.1 Gen 1 compliant (SS, HS, FS, and LS operation)

• USB pins are 5 V tolerant

• Self powered operation

• Four downstream USB 2.0/ USB 3.1 Gen 1 ports

• All downstream ports support individual port power and overcurrent sense

• All downstream ports are battery charge enabled (2.1A max per port)

• Can support up to 5A down stream Port Power at any one time

• Onboard SPI Flash for external downloadable firmware

• Low-cost 4-layer space saving design

• Operates from a single voltage (+12.0 V, regulated) external power supply

• Onboard 25 MHz crystal or external clock input

• Single onboard +5.25 V, 6 Amp regulator

USER’S GUIDE

Chapter 1. Overview

 2015 Microchip Technology Inc. DS50002306B-page 10

The Microchip EVB-USB5744 is designed for flexible configuration solutions. It can be
configured via default internal register settings, downloadable external firmware to an
onboard SPI Flash, through SMBus, or through the onboard configuration switches.
When configured with the default internal register settings, the device operates as a
USB 3.1 Gen 1 / USB 2.0 hub with four battery charge enabled USB ports and Micro­chip’s standard VID/PID/DID settings.

2.1 CONFIGURATION

2.1.1 External SPI Flash

Upon power-up, the USB5744 first looks for an external SPI Flash 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 device.

To select the SPI device, set the Config. Select switch to "SPI", position 1-2. The blue
LED will light. Note that the CFG_BC and CFG_Non-Rem options are now de-selected.
All configuration in SPI mode is done by the SPI.

EVB-USB5744

EVALUATION BOARD

USER’S GUIDE

Chapter 2. Getting Started

Note: If the SPI Flash is not properly programmed or has an invalid signature, the

USB5744 will default to internal defaults even if the SPI Flash is selected.

FIGURE 2-1: SPI SELECT

The 10 kΩ pull-up resistors (R42 and R58) on the SPI device’s Write Protect (WPn) and Hold
(HOLDn) pins must also be populated in order to use external flash. The 10 k
(R61) on the SPI_CE_N pin of the USB5744 must also be populated in order to select 60MHz
SPI operation, as opposed to 30MHz operation. Additionally there must be a jumper placed on

Ω pull-up resistor

 2015 Microchip Technology Inc. DS50002306B-page 11

EVB-USB5744 Evaluation Board User’s Guide

J10 in order to enable the SPI device.The external flash can be programmed using the Microchip
ProTouch MPT software tool which can be downloaded from the Microchip website at
http://www.Microchip.com/ProTouch.

Note: Refer to the Protouch MPT User Manual on using this software to program

the configuration.

2.1.2 SMBus

If an SPI Flash device is not found, the firmware checks if the SMBus is enabled. The
SMBus can operate in either legacy mode (USB 2.0 only) or advanced mode (access
to both USB 2.0 and USB 3.1 Gen 1 registers). When using SMBus, the default config­uration is for it to run in the advanced mode.

To select SMBus configuration, set the Config. Select switch to "Strap", position 2-3.
The green LED will light.

The SMBus must have correct pull up resistors applied by external circuitry to function
properly. The SMBus signals may be accessed at J8, pins 1 and 3.

Remember, if configured for SMBus operation the USB5744 will wait indefinitely for
data from the SMBus.

FIGURE 2-2: SMBUS SELECT

2.1.3 Configuration Source - Internal Default

When the USB5744 does not detect a valid SPI Flash image or SMBus configuration
upon power-up, the EVB-USB5744 uses internal default register settings. It also sets
the Vendor ID, Product ID, Language ID, and Device ID, and additional settings from
internal ROM code.

2.1.4 Strapping Option

If configuration is not done through SPI, additional configuration is available through
two functions: CFG_BC and CFG_Non-Rem. The controls are configured by selecting
on of six resistor values for each pin. These are read by the USB5744 device and the
BC and Non-Rem behavior of the downstream facing ports are determined.

DS50002306B-page 12  2015 Microchip Technology Inc.

To use the strapping option, set the Config. Select switch to "Strap", position 2-3. The
green LED will light. Select the desired CFG_BC and CFG_Non-Rem options by
enabling only one position for each of the Config_Bat_Chrg Select and Con­fig_Non_Rem Select switches (SW5 and SW6).

6 Reserved

2.1.5 Port Power Options: Port Enable and Port Disable Select

Any downstream facing port on the EVB-USB5744 can be disabled if desired. When
both DP & DM signals are pulled up to +3.3V, by default the USB5744 automatically
disables the port, reports the corrected number of available ports to the host, and drives
the PRT_CTRL line for the disabled port(s) low.

To enable a port, use its Port Enable switch to select the “EN.” position. The associated
“Enabled” LED will light.

To disable a port, slide its Port Enable switch to the “Dis.” position. The “Enabled” LED
will extinguish.

2.2 POWER SOURCE - SELF-POWERED

The EVB-USB5744 only supports self-powered operation, and is powered through one +12.0 V
regulated 'wall wart' external power supply. The power supply plugs into the 2.5 mm connector
J9 on the board. Alternatively, an external voltage can be injected onto the J6 Ext. 12 V header,
which is not populated by default. The +12.0 V feeds a 6 A regulator which outputs +5.25 V
across the board. This +5.25 V output supplies the +3.3 V and +1.2 V onboard regulators.

Switch Position LED

2.3 DOWNSTREAM PORT POWER CONTROL

USB power to the four downstream ports are controlled via port power controllers with
auto-discharge function. This provides up to 2.1 A of USB battery charging power to
each port, limited to a total of 5 A at any one time.
