Overview
The TUSB3410IVF, produced by Texas Instruments, is a USB to Serial Port Controller designed to bridge the gap between a USB port and an enhanced UART serial port. This device integrates an 8052 microcontroller unit (MCU) with 16KB of RAM and 10KB of ROM, enabling it to manage USB and serial port communications efficiently. The MCU operates at 24 MHz, providing 2-MIPS operation, and includes features such as a master I2C controller, 128-ms watchdog timer, and enhanced UART capabilities. The device supports USB 2.0 full-speed specifications and can be configured for both bus-powered and self-powered operations.
