TUSB3410IVFG4

Overview

The TUSB3410IVFG4 is a USB-to-serial bridge controller manufactured by Texas Instruments. It integrates an 8052-based CMOS microcontroller with USB 2.0 connectivity, enabling high-speed data transfers up to 921,600 bit/s. The device features 10K bytes of ROM, 16K bytes of program RAM, and 256 bytes of on-chip RAM. Key peripherals include two timers/counters, a watchdog timer, four GPIO ports, two DMA channels, and an I2C interface. Designed for applications requiring MSP430 Flash code download through the USB port, it supports serial UART communication with enhanced interface capabilities.

Feature Summary

• Integrated 8052-based microcontroller with USB 2.0 support
• High-speed serial data transfer rates up to 921,600 bit/s
• Includes 10K bytes ROM, 16K bytes Program RAM, and 256 bytes On-chip RAM
• Peripherals: 2 Timers/Counters, Watchdog Timer, 4 GPIO Ports, 2 DMA Channels, I2C Interface

Applications

• MSP430 microcontroller USB connectivity reference designs

Procurement Notes

Verify the specific suffix IVFG4 against official Texas Instruments documentation to confirm package type, temperature range, and RoHS compliance status. Ensure compatibility with required development tools such as the Keil PK51 Professional Developer's Kit or iSystem MetaICE-XF emulator for firmware deployment and debugging.

Selection Notes

Select this component when a combined USB host/device capability and serial UART conversion are needed within a single IC. The integrated 8052 core reduces external component count compared to discrete solutions. Verify that the available memory (10K ROM, 16K Program RAM) suffices for the target application's firmware requirements before finalizing the design.

Part Context

The TUSB3410 series serves as a bridge between USB interfaces and legacy serial devices. The TUSB3410IVFG4 variant specifically denotes the industrial temperature grade and VQFN package configuration. It is often utilized in evaluation kits like the TUSB3410 GPIOPDK to demonstrate connectivity solutions for Texas Instruments microcontrollers.

Replacement Considerations

Publicly confirmed direct substitute part numbers for the TUSB3410IVFG4 were not identified in the provided source material. Designers should consult Texas Instruments' official obsolescence notices or contact technical support for current alternative recommendations if this part is discontinued.
