Windows device driver information for TUSB3410 UART EVM

The TUSB3410 bridges the gap between the USB port and an enhanced UART serial port and contains all the necessary logic to communicate with the host computer using the USB bus. It contains an 8052 microcontroller unit (MCU) with 16 kilobytes (KB) of RAM that can be loaded from the host or from the external on-board memory via an I2C bus. It also contains 10K bytes of read only memory (ROM) that allow the MCU to configure the USB port at boot time. The ROM code also contains an I2C boot loader. All device functions, such as the USB command decoding, UART setup, and error reporting, are managed by the internal MCU firmware with the support of the PC host. The TUSB3410 can be used to build an interface between a legacy serial peripheral device and a PC with USB ports, such as a legacy-free PC. Once configured, data flows from the host to the TUSB3410 via USB OUT commands and then out from the TUSB3410 on the SOUT line. Conversely, data flows into the TUSB3410 on the SIN line and then into the host via USB IN commands.

Outdated Drivers?

Unless you update your drivers regularly you may face hardware performance issues.

To check your drivers you should manually verify every device on your system for driver updates

The hardware features of the TUSB3410UARTEVM include an Evaluation Module for the TUSB3410 while the evaluation module is a printed circuit board with a resident TUSB3410 and RS232 serial port, a USB–IF Certified Cable and RS232 Serial Cable. The software components include drivers which also enable the firmware stored on the host to download to the TUSB3410 integrated 8052 RAM. Next is the application firmware which is a binary object code version that performs RS232-to-USB conversion included in the driver install files. The utilities include an App Loader, which is a utility that enables firmware stored on the host to download to the TUSB3410 integrated 8052 RAM. It however does not update the EEPROM. Conflicts might occur where multiple devices are using the default VID and PID. The following devices are however not included; USB traffic monitoring utilities, compilers as the TUSB3410 is based upon the industry-standard 8052 microcontroller, a USB host and a power source as the TUSB3410 supports self-powered operation. It is highly recommended you run a free registry scan for and TUSB3410 UART EVM errors before installing any driver updates.
