EVM WARNINGS AND RESTRICTIONS
It is important to operate this EVM within the input voltage range of 4 V to 6 V and the output
voltage range of 3 V and 3.6 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.
Applyingloadsoutsideofthespecifiedoutputrangemayresultinunintendedoperationand/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.

Hardware and Software Required
Hardware and Software Required
The TUSB3210 generic EVM is designed for use with a personal computer
running a USB-enabled operating system. The PC should be USB 1.1
specification compliant. This implies that the BIOS, chipsets, and operating
systemareallUSB1.1specificationcompliant.IftheBIOSisnot specification
compliant, the system may not boot up when USB devices are connected at
power up, and the EVM may not function. Note that an ac/dc power supply
adapter is optional equipment (but included), since the EVM can function in
either bus-powered mode or self-powered mode.

1.2 Hardware Overview
The TUSB3210 EVM hardware platform is 11 cm wide by 13 cm long.
Throughout this document, text inside of parenthesis (ex.) denotes reference
designators found on the TUSB3210 EVM. See Figure 1–2 for a photograph
of the EVM. All jumpers are installed with the factory settings. Refer to the
jumper table for a description of settings, and make any required adjustments
before using the EVM.
The TUSB3210 EVM design allows great evaluation flexibility and provides a
platform that is practical and easy to use. The EVM is designed to run on a
12-MHzcrystalandusesanI2CEEPROM.TheEVMissetupforbus-powered
operation using a 5-V to 3.3-V voltage regulator. The UART port is disabled.
The firmware installed in the EEPROM allows USB HID-class-enabled
operating systems such as Windows98, Windows2000, WindowsME,
and MacOSto directly access it like a keyboard, although it does not have
one.
Reference firmware is installed and the source code is available to
developers.TheRS-232 port is available formonitoring8052MCUactivityfor
debugging purposes. The port uses a one-to-one serial port cable instead of
a null modem. Several test points have been added to the EVM for probing.
Carefully review all setting changes prior to powering the EVM, as improper
use could result in damage to some of the EVM components.
