在前面此间少年写过几篇帖子，简略地介绍了一下USB type C这个神奇的接口,下面有两篇文章 仅供大家参考：
小观一下 USB Type C
USB Type C 缺点
目前，据我所知，有三家厂商发布了 USB Type C 芯片
1、赛普拉斯
CCG1 提供了一个完整的USB Type-C 和USB 电源供应端口控制解决方案。
CCG1 的内核架构使能了一个基本的Type-C 解决方案， 通过备用模式复用支持，它可被扩展为一个能够提供高达100 W 电能的完整USB 电源。
CCG1 还是主动和被动线缆的Type-C 线缆 ID IC。CCG1 控制器检测了连接器插入、插入方向和VCONN 切换信号。
通过使用CCG1，将USB 电源供应添加到任意架构内变得 更加方便，这是因为CCG1 提供了控制信号（用于管理外部VBUS 和VCONN 电源管理解决方案）以及外部复用控制信号（用于大 部分使用单线缆的对接解决方案）。
从下图就可以看到正反两面插入开发板都是可以的。

2、TI
TPS65982
The TPS65982 is a stand-alone USB Type-C & Power Delivery (PD) controller providing cable plug and orientation detection at the USB Type-C connector. Upon cable detection, the TPS65982 communicates on the CC wire using the USB PD protocol. When cable detection and USB PD negotiation are complete, the TPS65982 enables the appropriate power path and configures alternate mode settings for internal and (optional) external multiplexers.

3、恩智浦
PTN5100 is a single port USB Type-C Power Delivery (PD) PHY and Protocol IC that provides Type-C Configuration channel interface and USB PD Physical and Protocol layer functions to a System PD Port Policy Controller (Policy Engine and Device Policy Manager, Alternate mode controller). It complies with USB PD and Type-C specifications and delta updates of PD spec. This IC is targeted for a wide range of platforms (Standard Notebook PCs, Desktop PCs, Chromebooks, Tablets, Convertibles, Smart phones) and PC Accessories (e.g. Docks, Monitors, Cable adapters etc.) applications. PTN5100 is architected to deliver robust performance, compliant behavior, configurability and system implementation flexibility that are essential to tide over interoperability and compliance hurdles in the platform applications.
Supports implementation of various system PD roles: P, P/C, C, C/P
Supports Type-C role configurability
Type-C role (DFP, UFP, DRP) is Non-Volatile Memory (NVM) and register
programmable based on OEM platform requirements
Implements UFP role pull down behavior to handle dead battery condition on
battery powered platforms
Supports register programmable and variable ‘Rp’ indication (for DRP/DFP usage
and accessory detection)
Implements 'Rd' indication on CC pin (for Device side implementation)
CC detection/indication scheme based on Type-C role
Indication of orientation detection via CC_ORIENT pin and status register(s)
Debug and Audio Accessory detection and indication in status register(s)
