USB Type-C port controllers add low-power options

August 20, 2015 // By Graham Prophet
Lattice Semiconductor’s port controllers offer space, cost and power efficient designs to support USB Type-C interfaces, enabling designers to quickly develop next-generation products.

These cost-effective USB Type-C port controllers deliver the reversible connector, intelligent power delivery and USB data: an expansion of Lattice’s USB Type-C product family sees the introduction of its latest SiI7012, SiI7013 and SiI7014 port controllers. Port controllers are used to configure the USB Type-C Upstream Facing Port (UFP) or Downstream Facing Port (DFP), detect cable orientation and negotiate Power Delivery (PD) on the USB Type-C connection.

The SiI7012 and SiI7013 port controllers offer a single integrated solution that can detect and decode Configuration Channel (CC) and Biphase Mark Code (BMC) messaging over USB Type-C connectors without the need for discrete components. These ICs work in conjunction with existing Application Processors (AP) and Embedded Controllers (EC) to provide cost-optimised USB Type-C port controllers. These solutions are compliant with the latest PD and CC requirements defined in the USB specifications.

The SiI7012 comes in a small CSP package suitable for smartphones, whereas the SiI7013’s QFN package is suitable for notebooks and accessories. The SiI7014 IC supports the auxiliary channel (AUX) and Hot Plug Detect (HPD) 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.
