EVM WARNINGS AND RESTRICTIONS

It is important to operate this EVM within the input voltage range of 4.75 V and the output
voltage range of 4.75 V and 5.25 V.

Exceeding the specified input range may cause unexpected operation and/or irreversible
damage to the EVM. If there are questions concerning the input range, please contact a TI
field representative prior to connecting the input power.

Applying loads outside of the specified output range may result in unintended operation and/or
possible permanent damage to the EVM. Please consult the EVM User’s Guide prior to
connecting any load to the EVM output. If there is uncertainty as to the load specification,
please contact a TI field representative.

During normal operation, some circuit components may have case temperatures greater than
50°C. The EVM is designed to operate properly with certain components above 60°C as long
as the input and output ranges are maintained. These components include but are not limited
to linear regulators, switching transistors, pass transistors, and current sense resistors. These
types of devices can be identified using the EVM schematic located in the EVM User’s Guide.
When placing measurement probes near these devices during operation, please be aware
that these devices may be very warm to the touch.

Required Hardware and Software

The TUSB3410 general-purpose input-output EVM was designed for use with
a personal computer running a USB-enabled operating system. The PC
should be USB 1.1 or USB 2.0 spec compliant. This implies the BIOS, chip­sets, and operating system are all spec compliant. If the BIOS is not spec com­pliant, the system may not boot when USB devices are connected at power
up and the EVM may not function. Note that the EVM can only function in the
bus-powered mode.

1.2 Hardware Overview

The TUSB3410 GPIO EVM hardware platform is 4,3 cm × 6,8 cm in width ×
length. Throughout this document, text inside of parentheses (ex.) is reference
designators found on the TUSB3210 EVM. See Figure 1–2 for a reference
picture of the EVM. First, all jumpers are installed with the factory settings. See
T able 2–3 for a description of jumper settings and make any required changes
before using the EVM. The TUSB3410 GPIO EVM is designed to allow great
flexibility in evaluation while being very easy and practical to use. The EVM is
designed to run using a 12-MHz crystal and an I
up for bus-powered operation using a 5-V to 3.3-V voltage regulator. The
firmware installed at the factory in the EEPROM is special USB keyboard
firmware, which makes it very easy for evaluation on any USB-enabled OS
without the need for a device driver. The firmware installed is reference
firmware and the source code is available for developers. The RS-232 port is
available for monitoring 8052 MCU activity for debugging purposes. The
RS-232 port requires a 1-to-1 cable, not a null-modem cable. Several test
points have been added to the EVM for probing. An LED (D2) displays the
suspend status of the TUSB3410 device. A USB cable should be plugged into
a USB port on a PC or USB hub and connected to the TUSB3410 EVM type-B
USB connector (U3).

TUSB3410 EVM Setup

2.1 TUSB3410 EVM Setup

The TUSB3410 general-purpose EVM is designed to support many USB
applications. The EVM comes in a default configuration that requires no
additional components on the EVM. A full description of the TUSB3410 device
is specified in the data manual. The PC must be running a USB-capable
operating system. Configure the EVM if required, based on desired settings
specified later in this section. Use a standard USB cable to connect the
TUSB3410 EVM to a downstream port of the PC or a USB hub tier.

2.2 Interfaces and USB Ports

The EVM uses a standard type-B connector for the upstream port. An I2C
serial interface is provided to access an I
embedded in the microcontroller and is connected to the RS-232 port on the
EVM. The RS-232 port connection can not be disabled by using the jumpers.
See jumper settings for more details. There are four buttons and four LEDs on
the EVM that can be used as general-purpose inputs and outputs to evaluate
how the system works.

2.6 Jumpers

Table 2–3 is provided to help set up and configure the EVM platform jumpers
for the desired mode of operation. The EVM can download firmware code from
the PC through a loading program (may or may not be supplied with your EVM)

or from an I

C EEPROM. JP2 and JP3 are used to connect P3.0 and P3.1 to
D3 and D4 respectively . JP4 is for separating the SCL pin of the I2C EEPROM
from SCL of the TUSB3410.

2.7 EEPROM

The I2C EEPROM is used to provide application-specific firmware. The
TUSB3410 automatically reads the EEPROM at power up via the I
header must be added to the application firmware before loading it into the
EEPROM. See the TUSB3410 data manual for a description of the header
definition. The header can be generated automatically using the I
header-generation utility software provided with the device.
