TUSB8040ARKMR Description

Short technical summary and product information.

The Texas Instruments TUSB8040ARKMR is a versatile four-port USB 3.0 compliant hub controller designed for high-speed data transfer and charging applications. It supports SuperSpeed USB, High-Speed, and Full-Speed connections on its upstream port, and offers similar support across its four downstream ports.

 

This hub controller features advanced USB 2.0 hub capabilities, including a Multi Transaction Translator (MTT) hub with four transaction translators, one per port. Each translator is equipped with four asynchronous endpoint buffers, enhancing throughput beyond the USB minimum requirements. The device is compliant with Battery Charging 1.2 specifications, supporting both Charging Downstream Port (CDP) and Dedicated Charging Port (DCP) modes.

 

Configuration options include support for an optional Serial EEPROM or SMBus slave interface for custom VID/PID, manufacturer, product strings, and serial numbers. Each downstream port can be independently enabled/disabled, marked as removable or permanently attached, and have battery charging enabled or disabled. The TUSB8040ARKMR operates within a temperature range of -40°C to 85°C and is housed in a 100-WQFN-MR (9x9) package, suitable for surface mount applications.

 

It requires a single 24-MHz clock input and does not need special drivers, ensuring seamless integration with operating systems supporting the USB stack. Status outputs provide information on upstream connection and suspension states for both High-Speed and SuperSpeed USB connections.
