TUSB8042RGCT

Controllers Overview

The TUSB8042RGCT is a four-port USB 3.1 hub controller manufactured by Texas Instruments, designed for SuperSpeed data transfer at rates up to 5 Gb/s. It operates within a supply voltage range of 990 mV to 3.6 V and supports standard I2C interface communication. The device functions in an ambient temperature environment between 0°C and +70°C, drawing a typical operating current of 15 µA. It is housed in a compact 64-pin VQFN package with dimensions of 9 mm, suitable for surface mount applications requiring high-density integration.

Controllers Feature Summary

• Supports four downstream ports for simultaneous connection of multiple USB devices
• Enables SuperSpeed data transmission compliant with USB 3.1 standards
• Integrates I2C interface for host configuration and control

Controllers Applications

• Desktop computer hubs
• All-in-one printers
• Industrial automation controllers

Controllers Procurement Notes

Verify the specific suffix RGCT against the manufacturer's official datasheet to confirm the package type and reel specifications. Ensure compatibility with the target PCB footprint for the 64-VQFN form factor. Confirm that the procurement channel provides genuine components with traceable origin to avoid counterfeit risks associated with integrated circuit supplies.

Controllers Selection Notes

Select this component when a four-port solution supporting USB 3.1 SuperSpeed is required for commercial or industrial environments. Compare power consumption metrics against alternatives if battery-operated constraints exist, noting the low standby current. Verify that the system design accommodates the thermal requirements for operation up to 70°C without additional cooling infrastructure.

Controllers Part Context

This part belongs to the TUSB8042 series of USB hub controllers from Texas Instruments. It serves as a successor to earlier USB 3.0 hub solutions, offering enhanced speed capabilities while maintaining similar pinout configurations for easier migration. The series includes variants such as the TUSB8042A and TUSB8043, which may offer extended temperature ranges or different feature sets.

Controllers Replacement Considerations

The TUSB8042ARGCT is a related variant within the same family. Verify functional equivalence regarding port count and speed before substitution. Check for any differences in operating temperature ranges or package markings that might affect mechanical assembly.
