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.

TUSB3210 Setup
2-2
2.1 TUSB3210 Setup
The TUSB3210 EVM is designed to support many USB applications. The
jumpers allow the flexibility to configure the EVM in various modes for
evaluation purposes. Note that some modes require additional components
not included with the EVM kit. The EVM comes in a default configuration that
requires no additional components on the EVM. A full description of the
TUSB3210 device is specified in the data manual. The PC must be running a
USB-capable operating system.
If necessary, configure the EVM based on the desired settings specified later
in this section. Use a standard USB cable to connect the TUSB3210 EVM to
a downstream port on the PC or to a USB HUB tier.
2.2 Interfaces and USB Port
The EVM uses a standard type-B connector for the upstream port. An I2C
serial interface is provided to access an I2C EEPROM. A UART port is
embedded in the microcontroller and is connected to the RS-232 port on the
EVM. The RS-232 port connection can be broken using the jumpers. See
jumper settings for more details. All GPIO signals are available on the 50-pin
connector JP1 for use by the specific application.
2.3 Power Supplies
TheTUSB3210EVMrequiresasinglepositive5-Vpowersupplyforoperation.
There are two options for supplying power to the EVM:
-Self-powered mode: a switching 5-V dc power supply plugged into (J1)
-Bus-powered mode: 5-V power is supplied by the USB cable.
Notethatthesupply needs to have a ratingofatleast0.5A.TheEVMmayfail
tooperateproperlywithlesspower.Anonboardlow-dropoutregulatorisused
to generate a 3.3-V supply from the 5-V external supply. The red LED (D4) is

UART.

JP3 Position 1–2 on: connect P3.1 to T1IN; position 1–2 off: disconnect P3.1 from T1IN
JP4 Position 1–2 on: enable RS–232 port; position 1–2 off: disable RS–232 port
2.6 EEPROM
The I2C EEPROM is used to provide application-specific firmware. The
TUSB3210 automatically reads the EEPROM at power up via the I2C bus. A
header must be added to the application firmware before loading into the
EEPROM. Please refer to the TUSB3210 Bootcode document for a
description of the header definition. The header may be generated
automatically using the I2C Header Generation Utility software provided with
the device.
The EVM ships with a preprogrammed EEPROM that has either keyboard
controller firmware or compact flash reader firmware. It enumerates properly
when connected to a USB host.
