Now sampling is the small footprint, integrated USB Type-C cable controller solution with power delivery (PD). In USB 3, cables and interconnects are active, and on every connection event there is a negotiation to determine the upstream/downstream status of the connected device, and the power levels that are requested and delivered (or deliverable). “Type-C” designates the new, reversible miniature connector that handles the higher power and data rates of USB 3.1. Optimised for 2.4-mm thin USB Type-C cable connectors, the programmable EZ-PD CCG2 controller is fully capable of supporting any USB Type-C Downstream Facing Port (DFP) or Upstream Facing Port (UFP) applications. EZ-PD CCG2 is available in a 3.3 mm ² wafer level chip scale package (WLCSP) and is claimed as the first programmable solution to fully integrate both the Type-C transceiver and termination resistors needed for Type-C communication.
The USB Type-C standard is gaining rapid support with top-tier PC makers by enabling slim industrial designs, easy-to-use connectors and cables, the ability to transmit multiple protocols, and 100W PD—a significant improvement over the previous 7.5W standard. However, the Type-C standard requires an Electronically Marked Cable Assembly (EMCA) that can report the characteristics a cable supports, such as current carrying capability, protocols supported, and vendor identification. A standard MCU may be used for the EMCA implementation, but it makes the design complex by requiring multiple external ICs and passive components. Cypress says its EZ-PD CCG2 Type-C controllers solve this challenge with integration and bill-of-materials savings with only five or fewer external components required. This suits them for Passive and Active EMCA cables, as well as for cable adapters that enable users to connect devices with a Type-C port to older devices with legacy ports such as DisplayPort or HDMI.
“Cypress’s CCG1 controllers opened up the path for quick adoption of USB Type-C for our top-tier customers, bringing the standard’s easy plug-and-play ability, multi-protocol connectivity, and power delivery to market,” said Ajay
