TUSB3410UART EVM Board Overview
The TUSB3410UART evaluation module (EVM) provided in this kit is specifically designed to
showcase the TUSB3410 as a compact USB to serial interface bridge. TUSB3410 interfaces
full-speed (12Mbps) USB to a high-speed UART. The EVM adds an RS232 driver to interface to
standard serial port devices.
Included in the TUSB3410 EVM design are an I2C serial EEPROM, a 12MHz crystal, and a 5V-
to-.3V low-dropout voltage regulator. The EEPROM contains code to boot the TUSB3410’s
internal 8052 micro controller and other configuration parameters while the 12MHz crystal
provides the clock source for the device. The 5V-to-3.3V voltage regulator converts the 5V USB
bus power to 3.3V, which is required by the TUSB3410.
The EVM operates from 5V USB bus power. A TUSB3410 solution may be either self-powered
or bus powered.
The EVM is 3cm by 6cm. See Fig. 1.

System Setup and Procedure
Download the software per the instructions in the “Getting Started” document accompanying this
kit. Install the driver according to the instructions.
Please run the installer included in the driver package rather than allowing Windows to conduct
the installation.
While it is possible to do a proper install by first attaching the EVM and allowing
Windows to complete the installation, running the installer is more automated. The installer
seeks out and resolves any conflicts that could prevent the driver from working properly.
Be sure to run the appropriate version of the installer depending on your version of Windows
(Windows 98/ME or Windows 2000/XP). The installer places both the driver and a firmware file
that will be downloaded to the EVM when it is attached.
Fig. 2 shows the typical system setup.
