EZ-PD™ CMG1 USB-C EMCA Controller

EZ-PD™ CMG1 is Cypress’ dedicated Electronically marked cable assembly (EMCA) controller targeting passive non-Thunderbolt and Thunderbolt Type-C cables. CMG1 supports Power delivery 3.0, Type-C 1.3, integrated VBUS-CC short protection, VBUS-VCONN short protection and ESD protection all offered in a small footprint 9-ball WLCSP package.

CMG1 is built to operate from 2.7-5.5 V VCONN supply range with a 40 byte of storage for vendor- and cable-specific configuration data.

CMG1 passive EMCA paddle card reference design is available here to speed up the design cycle.

Product Features

  • Supports USB PD3.0 spec and USB Type-C spec version 1.3
  • Integrated high-voltage protection on CC, VCONN1, and VCONN2 pins to protect against accidental shorts to the VBUS pin on the Type-C connector
  • Integrated 40 bytes for storing vendor- and cable-specific configuration data
  • Termination resistor RA on VCONN1 and VCONN2
  • Supports RA weakening to reduce power consumption
  • IEC ESD protection on VCONN and CC
  • Wide operating voltages: 2.7 – 5.5 V
  • Packages: 9-ball WLCSP (1.35 x 1.35 mm)
  • Supports industrial temperature grade (-40 °C to +85 °C)

USB Type-C Specification

USB Type-C is the new USB-IF standard that solves several challenges faced by today's Type-A and Type-B cables and connectors. USB Type-C uses a slimmer connector (measuring only 2.4-mm in height) to allow for increasing miniaturization of consumer and industrial products. The specification allows for fully reversible plugs and enables transport of both USB signals and PCIe or DisplayPort signals on the same connector. The Type-C specification aslo increases the power delivery capability from 7.5 W to 100 W.
