TUSB8041RGCR

Controllers Overview

The TUSB8041RGCR is a four-port USB 3.0 hub controller manufactured by Texas Instruments, designed for high-speed data transfer applications. It operates at Super Speed (SS) with a data rate of 5 Gb/s and supports the USB 3.0 standard. The device functions within a supply voltage range of 990 mV to 3.6 V, utilizing working voltages of 1.1 V and 3.3 V. It draws a typical operating current of 28 mA and is rated for an extended industrial temperature range from -40°C to +85°C. The component is housed in a compact VQFN-64 package suitable for surface mount technology (SMD/SMT). It features I2C interface control and includes humidity sensitivity protection mechanisms.

Controllers Procurement Notes

Verify the specific suffix 'RGCR' against official Texas Instruments documentation to confirm the exact reel quantity and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the VQFN-64 package. Confirm that the procurement source provides valid traceability and authenticity guarantees for integrated circuits. Check for any recent product change notices regarding packaging or material composition updates.

Controllers Selection Notes

Select this component when a four-port USB 3.0 solution is required with support for the -40°C to +85°C industrial temperature range. Consider the VQFN-64 package dimensions during layout planning to ensure adequate thermal dissipation and soldering clearance. Verify that the host system can provide the necessary 1.1 V and 3.3 V power rails efficiently. Compare against the TUSB8040A1 series if lower power consumption or different pinout configurations are prioritized over the specific feature set of the TUSB8041.

Controllers Part Context

The TUSB8041 belongs to the TUSB804x family of USB 3.0 hub controllers from Texas Instruments. This family addresses the growing demand for high-bandwidth connectivity in modern computing platforms. The RGCR variant specifically denotes the commercial-grade temperature range and reel packaging format. It serves as a bridge between host controllers and multiple downstream USB peripherals, facilitating efficient data routing and power distribution in complex electronic systems.

Controllers Replacement Considerations

The TUSB8040A1RKMR is listed as a similar alternative in distributor databases. However, it carries a 'Not Recommended for New Designs' status. Verify pin-to-pin compatibility and functional equivalence through official datasheets before considering substitution. The TUSB8043RGCT offers USB 3.1 support but may require design adjustments due to protocol differences.
