Purpose
The RT1710S is a type-C E-marked IC. It can request cable current ,speed limit and cable type. This document explains the function and use of the RT1710S evaluation board (EVB).
Introduction
General Product Information
The RT1710S is a Type-C cable ID for active and passive cables.All USB Full-Featured Type-C cables shall be electronically marked. Electronically marked cables shall support USB Power Delivery Structured VDM Discover Identity command directed to SOP'. This provides a method to determine the characteristics of the cable, e.g. its current carrying capability, its performance, vendor identification, etc. This may be referred to as the USB Type-C Cable ID function. RT1710S is available in a WDFN-8L 2x2 package.
