Lattice Semiconductor Corporation has announced the expansion of its USB Type-C product family with the introduction of its latest SiI7012, SiI7013 and SiI7014 port controllers. Port controllers are used to configure the USB Type-C Upstream Facing Port or Downstream Facing Port, detect cable orientation and negotiate Power Delivery on the USB Type-C connection.

The SiI7012 and SiI7013 port controllers can detect and decode Configuration Channel and Biphase Mark Code messaging over USB Type-C connectors without the need for discrete components. These ICs work in conjunction with existing Application Processors and Embedded Controllers to provide cost-optimised USB Type-C port controllers. The SiI7012 comes in a CSP package suitable for smartphones, whereas the SiI7013's QFN package is suited for notebooks and accessories.

The SiI7014 IC supports the auxiliary channel and Hot Plug Detect signal required to implement DisplayPort over USB Type-C. In addition, both the SiI7013 and SiI7014 support multiple Type-C ports that are required for notebooks.
