TUSB3410IVF - USB to UART Bridge | Texas Instruments
MPN: TUSB3410IVF ✓ نشطTUSB3410IVF نظرة عامة
A USB-to-UART bridge is an interface IC that translates between the packet-based Universal Serial Bus and a character-oriented serial peripheral. Positioned within interface ICs, bridge controllers, serial interface devices, and data-conversion semiconductors, the TUSB3410 reduces the need for a host to implement a proprietary serial protocol directly. Its integrated controller manages USB-to-serial command exchange while external circuitry connects to the system-side serial interface.
The TUSB3410IVF combines a 3 V to 3.6 V operating range with integrated ROM and an industrial temperature grade. Its supported UART, I2C, and IrDA connectivity allows one bridge to serve conventional serial equipment or infrared-oriented peripherals. The 32-lead LQFP package provides a conventional surface-mount footprint suitable for automated assembly and compact industrial controller layouts.
The device is built around an 8052-compatible microcontroller core with 10 kB of ROM, as identified in the manufacturer product listing. Firmware or configuration can be loaded by the USB host or through external onboard memory using I2C, according to the device documentation. This architecture makes the bridge useful when peripheral behavior must be adapted through firmware rather than implemented entirely in fixed hardware.
Typical applications include industrial serial adapters, USB-connected control panels, legacy equipment interfaces, infrared data links, configuration ports, and embedded systems requiring a USB uplink from a UART-based peripheral. The industrial temperature specification supports equipment deployed in factory, instrumentation, and communications environments where consumer-temperature components may be unsuitable.
Designers should preserve the exact pin assignments and reference circuitry shown in the manufacturer datasheet, especially for external memory, clock, USB, and serial-interface connections. Power and decoupling should follow the recommended topology, while USB signal routing requires a controlled impedance path and short connection from the controller to the connector.
This product page combines the official device description, package and temperature information, replacement considerations, and design-focused guidance. It highlights the practical trade-offs between the industrial TUSB3410IVF and related TUSB3410 ordering variants while keeping sourcing and technical decisions tied to manufacturer documentation.

التطبيقات النموذجية
TUSB3410IVF مناسب لـ 6 التطبيقs: Industrial USB-to-UART Adapter, Legacy Equipment USB Retrofit, IrDA Data-Link Adapter, Instrumentation Control Console, USB Configuration Port, Factory Automation Serial Gateway.
Industrial USB-to-UART Adapter
The TUSB3410IVF fits an industrial USB-to-UART adapter because it operates from 3 V to 3.6 V and is rated from -40°C to +85°C. Its integrated 8052 core and 10 kB ROM manage USB-to-serial command handling, while the UART interface connects to legacy equipment. The 32-pin LQFP package supports compact surface-mount construction, but USB differential routing, connector placement, and firmware loading must follow the manufacturer’s reference implementation.
موصى به
Legacy Equipment USB Retrofit
The TUSB3410IVF can modernize equipment that originally communicates through a UART or IrDA peripheral by presenting that serial function to a modern USB host. Its 8052 controller core and I2C configuration path make the bridge adaptable to firmware-based peripheral identification and control. For long cable runs or legacy logic levels, add the appropriate line transceiver and isolation; the bridge itself handles USB-side enumeration rather than solving every physical-layer requirement.
موصى به
IrDA Data-Link Adapter
The TUSB3410IVF is applicable to an IrDA-oriented adapter because IrDA is one of its documented serial interface options alongside UART and I2C. A USB host can use the bridge as the communication path to an infrared peripheral while the integrated controller handles USB command exchange. Actual infrared range and signaling depend on the external IrDA transceiver and optical hardware, so the bridge should be paired with a compatible physical-layer device and reviewed against timing requirements.
موصى به
Instrumentation Control Console
The TUSB3410IVF is well suited to a USB-enabled instrumentation console that must connect a host computer to an internal UART-based controller. Its industrial temperature range supports unheated equipment cabinets, while the 8052 core and 10 kB ROM provide a dedicated interface processor rather than placing USB enumeration burden on the main embedded controller. Power, USB routing, and firmware loading should be designed according to the datasheet, with logic-level conversion added when the target instrument uses a different voltage domain.
موصى به
USB Configuration Port
The TUSB3410IVF can implement a USB configuration port for an embedded system whose embedded controller is configured through UART, I2C, or IrDA. Firmware may be loaded by the USB host or from external onboard memory through I2C, allowing the bridge to participate in device initialization. Designers should define the enumeration descriptors, bootloader behavior, timeout handling, and recovery path before production use, then validate them on the target USB host and operating-system combination.
موصى به
Factory Automation Serial Gateway
The TUSB3410IVF can serve as the USB uplink in a factory automation gateway that connects a host computer to controller boards or service equipment. Its -40°C to +85°C industrial rating covers many unheated enclosure environments, while UART, I2C, and IrDA support allows one bridge design to cover several service-port configurations. For motor-control or noisy factory environments, maintain separation between USB and power paths, use appropriate transceiver protection, and validate electrostatic and conducted-immunity performance at the system level.

ملاحظات التصميم
Place the TUSB3410IVF close to the USB connector and route the D+ and D+ signals as a matched differential pair. Minimize vias, stubs, and discontinuities, use the geometry specified by the PCB stack-up, and provide the connector-side ESD protection required by the system design. Keep the USB pair away from switching-power nodes and high-current motor traces.
Operate the bridge only within its specified 3 V to 3.6 V supply range. Place the recommended input and bypass capacitors adjacent to the appropriate supply and ground pins, and check startup sequencing if the bridge shares a rail with external memory or a microcontroller. Confirm that USB signaling levels, I2C pull-ups, and any external memory operate from compatible supply domains.
Use the datasheet pin-configuration diagram as the authority for all 32 LQFP connections, including clock, reset, serial, I2C, and USB signals. Preserve the indicated ground connections and avoid assigning functions by position alone. When external onboard memory is used, keep its address, data, and clock routing compact and validate timing with the actual pull-up and loading configuration.
Do not treat TUSB3410VF as an unconditional replacement for TUSB3410IVF: its documented minimum temperature is 0°C rather than -40°C. Also avoid assuming that USB-to-UART support includes RS-232, RS-485, or IrDA optical signaling. Add the required transceiver, protection, and logic-level conversion, and validate host enumeration, firmware loading, and peripheral communication together.
