2 Detailed Description

This section of the document discusses what the CC controller portfolio of the USB team contains, and key differentiation criteria to help in the part selection process.

There are four main product families and three generations of parts in the CC controller portfolio. Figure 2-1 shows a visualization of the product families and the generations.

The four families of products can be divided based on the following identifiers:

  1. PD Family: This family of products supports PD PHYs. The only part in this family is the TUSB422 which was released to be fully compliant with PD specification revision 1.2. For newer PD offerings, reach out to TI's PD controller team.
  2. Automotive Family: The family of products that are AEQ Q100 qualified. The only part in this family of products is the TUSB319-Q1. This is a DFP only CC controller.
  3. GPIO Family: This family of products were designed for GPIO applications. They are all designed with an external DIR which is used to control a USB Superspeed MUX. These parts are best designed for USB 3.x applications of a USB Type-C system. There are three parts in this family of products: TUSB321I, TUSB321AI, and TUSB322I.
  4. I2C Family: This family of products are designed for I2C and GPIO applications. The products are designed to operate with USB 2.0 systems in GPIO mode as the products do not have an external DIR pin. However, in I2C mode these parts can operate in USB 2.0 and USB 3.x applications. These parts also provide the flexibility of an EN pin which can be active high or active low. The parts in this family are: TUSB230I, TUSB320LI, TUSB320HI, TUSB320LAI, and TUSB320HAI.

In addition to the four families of products, TI's CC controller portfolio can further be broken down into generations. The following figure highlights the key changes between generations. Keep in mind all three generations of products exist independently, meaning that a newer generation does not make older generations obsolete. The PD controller family is not included here as there is only one generation of the TUSB422.
