CPS8821B
Application
Passive USB Type-C cables such as full-featured C-to-C cables
This chip is an electronic marker for USB Type-C passive cables with extremely low BOM cost, which makes the cable connectors compact. This chip supports structured VDM Discover Identity Command directed to SOP’, which provides a method to determine the characteristics of cables, e.g. current-carrying capability, performance and vendor identification. Being compliant to PD3.0 V2.0, this chip also supports extended message Get_Manufacture_Info and will respond by returning a Manufacture_Info message containing manufacturer info data block (MIDB). Customized data can be stored in the MTP and in-cable programmed through CC PIN.
