E-Marker chips are used in USB Power Delivery cables, including USB Type-C, to report the characteristics a cable supports, such as current-carrying capability, protocols supported and vendor identification. The USB Type-C standard is gaining rapid support with top-tier PC and electronics manufacturers by enabling slim industrial designs, easy-to-use connectors and cables, and the ability to transmit multiple protocols and deliver up to 100W of power. The USB Type-C standard’s 2.4-mm-high connector plug is significantly smaller than current 4.5-mm USB Type-A standard connector. It also allows for transport of USB signals and PCIe or DisplayPort signals on the same connector.
“USB Type-C is revolutionising universal connectivity and enabling new usage models for computing and mobile applications,” said Jeff Ravencraft, USB-IF President and COO. “The programmability and field-upgradability of our EZ-PD USB Type-C solutions has enabled our customers to make last-minute changes using reliable and compliant USB-IF certified E-Markers,” adds Ganesh Subramaniam, Senior Director of the USB product line at Cypress.
The EZ-PD CCG1 USB Type-C port controllers are based on Cypress’s PSoC 4 programmable system-on-chip architecture. PSoC’s programmability enabled Cypress to integrate the transceiver for USB Type-C communication within a matter of weeks. The controllers provide design flexibility for multiple USB Type-C applications such as cables, power adapters, notebooks, dongles and monitors.
Optimised for 2.4-mm thin USB Type-C cable connectors, the programmable EZ-PD CCG2 controller is capable of supporting any USB Type-C Downstream Facing Port (DFP), Upstream Facing Port (UFP) or Dual Role Port (DRP) applications. EZ-PD CCG2 is available in a 3.3 mm ² 20-ball Wafer Level Chip Scale Package (WLCSP), a 14-pin DFN and a 24-pin QFN. EZ-PD CCG2 is, Cypress says, the first programmable solution to fully integrate the USB Type-C transceiver, system-level ESD protection, and termination resistors needed for all USB Type-C applications.
EZ-PD CCG1 (CYPD1103) and EZ-PD CCG2 (CYPD2103) controllers have received Product Test IDs 1095059 and 1095054 respectively.
