Description for the TUSB3410

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 I2C. 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 I2C 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.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships  tube or tray  devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
