TUSB8042A1RGCR

Controllers Overview

The TUSB8042A1RGCR is a four-port USB 3.2 Gen 1 hub controller manufactured by Texas Instruments, designed for high-speed data connectivity in compact electronic systems. It operates within a supply voltage range of 990 mV to 3.6 V and supports SuperSpeed data rates up to 5 Gb/s. The device utilizes a VQFN-64 package suitable for surface-mount installation and functions with I2C interface control. It maintains an operating temperature range from -40°C to +85°C and draws a typical quiescent current of 15 µA. This component integrates essential hub logic for managing multiple downstream USB connections while ensuring compliance with USB 3.2 standards.

Controllers Feature Summary

• Supports four independent downstream ports for simultaneous device connectivity
• Enables SuperSpeed data transfer capabilities compliant with USB 3.2 Gen 1 specifications
• Integrates internal pull-up and pull-down resistors for simplified configuration of power management pins

Controllers Applications

• Desktop computer expansion docks requiring multiple peripheral connections
• Industrial embedded systems needing robust USB connectivity in extended temperature ranges
• Portable computing devices utilizing space-efficient surface-mount packaging

Controllers Procurement Notes

Verify the specific suffix '1' against the manufacturer's official documentation to confirm pinout or electrical variations compared to standard variants. Ensure compatibility with I2C host controllers and validate thermal performance within the specified operating temperature range during system integration.

Controllers Selection Notes

Select this component when a four-port USB 3.2 Gen 1 solution is required with low standby power consumption. Consider the VQFN-64 package constraints for PCB layout and ensure the host system provides stable 1.1 V and 3.3 V power rails. Verify that the application does not require billboard mode functionality, which is reserved for other models in the series.

Controllers Part Context

This part belongs to the TUSB8042 family of USB hub controllers, representing an evolution toward USB 3.2 Gen 1 standards. It shares architectural similarities with the TUSB8042 and TUSB8041 but offers updated feature sets aligned with newer USB specifications. The family focuses on providing reliable hub functionality for modern computing platforms.

Controllers Replacement Considerations

The TUSB8042AIRGCR serves as a direct functional substitute within the same package and specification profile. Designers should verify pin-to-pin compatibility and review any minor updates in the datasheet revision history before swapping components.
