1.3 Description
The TUSB3410 device provides bridging between a USB port and an enhanced UART serial port. The
device contains an 8052 microcontroller unit (MCU) with 16KB of RAM that can be loaded from the host or
from the external onboard memory through an I
2
C. The device also contains 10KB of ROM that allows the
MCU to configure the USB port at boot time. The ROM code also contains an I
2
C bootloader. All device
functions (such as the USB command decoding, UART setup, and error reporting) are managed by the
internal MCU firmware in unison with the PC host.
