TUSB8040A1RKMR Description

Short technical summary and product information.

The TUSB8040A1RKMR from Texas Instruments is a USB 3.0 compliant hub controller designed for high-speed data transfer applications. This device supports SuperSpeed USB connections at 5Gbps, offering four downstream ports that are individually configurable for SuperSpeed, high-speed, full-speed, or low-speed connections.

 

Key features include support for USB 2.0 hub functionalities with a Multiple Transaction Translator (MTT) hub, providing four transaction translators, each with four asynchronous endpoint buffers for enhanced throughput. The controller also supports battery charging applications, functioning as a Charging Downstream Port (CDP) or Dedicated Charging Port (DCP) according to Battery Charging 1.2 and YD/T 1591-2009 standards.

 

Packaged in a 100-WQFN-MR (9x9 mm) with an exposed pad, the TUSB8040A1RKMR operates within a temperature range of 0°C to 70°C and requires a supply voltage between 3V and 3.6V. It offers per-port or ganged power switching and overcurrent notification inputs, along with status outputs for upstream connection and suspension states. Configuration can be managed via an optional serial EEPROM or SMBus target interface.

 

Note: This part is not recommended for new designs. Consider the TUSB8042A as a newer generation alternative.
