说明

The TUSB3410 provides bridging between a USB port and an enhanced UART serial port. The TUSB3410 contains all the necessary logic to communicate with the host computer using the USB bus. It contains an 8052 microcontroller unit (MCU) with 16K bytes 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 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 under the auspices 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.
