USB Type-C port controllers enable quick development

Expanding its USB Type-C product family, Lattice Semiconductor has introduced three port controllers which deliver space, cost and power efficient designs that provide flexibility. The SiI7012, SiI7013 and SiI7014 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 ideal 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.

Cheng Hwee Chee, Senior Director, Consumer Marketing, Lattice Semiconductor, commented: “Our cost-effective USB Type-C port controllers deliver the critical functionalities that manufacturers need - a reversible connector, intelligent power delivery and USB data. We’re excited to offer a broadened portfolio of USB Type-C products to support the rapidly growing USB Type-C market.”
