TUSB3410VFG4

Overview

The TUSB3410VFG4 is a USB-to-serial port controller manufactured by Texas Instruments, designed to bridge USB 2.0 Full Speed (12 Mb/s) connections with serial interfaces such as RS-232 and IrDA. Operating within a voltage range of 3 V to 3.6 V, the device draws a typical operating current of 15 mA. It supports data transfer rates up to 921,600 bit/s for serial communication and facilitates MSP430 Flash code downloads via the USB port. The component is housed in a VQFN-32 surface-mount package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates USB 2.0 Full Speed interface with RS-232/IrDA serial ports
• Supports high-speed serial data transfers up to 921,600 bit/s
• Enables direct MSP430 Flash code download through the USB connection
• Operates on a single 3.3 V supply with low quiescent current consumption

Applications

• MSP430 microcontroller connectivity reference designs
• Embedded system serial port expansion
• Industrial control equipment requiring USB-to-serial conversion
• Consumer electronics utilizing IrDA or RS-232 interfaces

Procurement Notes

Verify the specific suffix 'VFG4' against official Texas Instruments documentation to confirm pinout compatibility and RoHS status. Ensure that ordering suffixes do not alter functional parameters unless explicitly stated in the datasheet. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when a USB 2.0 Full Speed interface is required to replace legacy RS-232 or IrDA connections. It is suitable for applications needing low power consumption and support for MSP430 firmware updates. Consider the VQFN-32 package constraints for PCB layout and thermal management during the design phase.

Part Context

The TUSB3410 series serves as a bridge controller within Texas Instruments' USB interface portfolio. It simplifies the integration of USB connectivity into systems previously reliant on standard serial ports. The device is often paired with development kits like the TUSB3410UARTPDK for rapid prototyping and validation of serial communication protocols.

Replacement Considerations

Publicly confirmed substitute part numbers for the TUSB3410VFG4 are not available in the provided source material. Verify compatibility with alternative USB-to-serial controllers based on specific interface requirements and package dimensions.
