• 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.”

1.3 GENERAL DESCRIPTION

The EVB-USB2642 is a demonstration and evaluation platform featuring the USB2642
Ultra Fast USB 2.0 Multi-Format Flash Media Controller, the UCS1001 Port Power
Controller with charger emulation and the USB hub combo on a 4-layer RoHS
compliant Printed Circuit Board (PCB). It is designed to support internal default
settings, an external certification chip, an SMBus header interface and an SPI flash
both for external firmware download, and also an external I
functionality.

An 8-Mbit SPI flash device can be populated on the evaluation board to provide
firmware updates via USB by using the provided USBDM utility. For more information,
please see the USBDM manual.

The default configuration can be changed by the SPI flash device, the SMBus header
interface or the external certification chip. Alternatively, the default configuration can be
changed by installing an EEPROM into the provided footprint. When this is done, the
SPI flash device must be removed to avoid signaling conflicts. Figure 1-1 and

Figure 1-2 show the top and bottom level silk screen and copper layers, respectively.

Chapter 2. Getting Started

2.1 INTRODUCTION

The EVB-USB2642 is configured by internal default registers. In this default
configuration, it operates as a USB 2.0 combo device with a 3-port USB hub (two
external ports) and a Flash Media Controller with standard VID/PID/DID settings and
USB to I

The UCS1001 on port 3 is configured to the data Pass-Through mode by default.

2.2 EVB-USB2642 CONFIGURATION

The EVB-USB2642 is designed for flexible configuration solutions. It may be
configured to operate with default internal register settings, USB host downloadable
configuration via SMBus header interface or EEPROM or USB host downloadable
external firmware to an SPI flash.

The UCS81001 can be configured using the J9, J10, J11 jumpers at startup or via the
EVB-USB2642 GUI. In the default mode, M1, M2 and EM_EN are set to ‘100’.

5 1 0 1 Dedicated Charger Emulation Cycle

6 1 1 0 Data Pass-through

7 1 1 1 BC1.2 CDPDta

Note 1: Per the BC1.2 specification, BC1.2 SDP behaves the same as the Data

Pass-Through mode with the exception that it is preceded by a VBUS
discharge when the mode is entered.

For more information, please visit the UCS1001 page.

When the EVB-USB2642 does not detect an EEPROM or a valid SPI flash image upon
power-up, the EVB-USB2642 uses internal default register settings. It sets the Vendor
ID, Product ID, Language ID, Device ID and a few other selections from internal ROM
code.

2.2.1 Configuration Source – External Certification Chip

When an iPhone, iPad or iPod is connected to the USB2642 evaluation board’s USB
interface, the external certification chip can communicate via the upstream
microprocessor over the USB to I
attached, the external certification chip is not involved in the data communication
between the control application and attached device.

Note: If the certification chip is installed, the 10.0 kΩ pull down resistor R26 must

also be installed.

EVB-USB2642 Evaluation Board User’s Guide

2.2.2 Configuration Source – External SPI Flash

The installed SPI flash is initially blank. In this scenario, the internal firmware will
execute. External firmware updates can be downloaded via USB using the utility
USBDM to the SPI flash. After downloading, the EVB-USB2642 will execute from the
SPI flash.

Note: If the SPI flash is installed, the 10.0 k

Ω pull up resistor R13 must also be

2.2.3 Configuration Source – External EEPROM

Upon power-up, the EVB-USB2642 looks for an attached EEPROM on its I2C interface.
The EVB-USB2642 provides a footprint at U10 where an external EEPROM
(embedded in a DFN8 package of type 24C0x) can be soldered to customize the Media
Controller’s settings. The EEPROM contains 512 bytes of user customizable settings.
Among the settings are Vendor ID, Product ID and Device ID numbers. To use the
EEPROM, the SPI flash device U4 must be removed first.

Note: If the EEPROM is installed, the 10.0 kΩ pull up resistor R13 must also be

installed.

2.2.4 Configuration Source – USB Upstream

The EEPROM supporting the USB2642 is configured with the USBDM configuration
tool via a USB2642 cable connected to the upstream connector. This tool allows for
modification of Vendor ID, Product ID, Language ID, Device ID and other configuration
settings.

For more information, please see the USBDM manual.
