上图DFP (Downstream Facing Port)也就是主， UFP (Upstream Facing Port) 为从。 除了DFP、UFP，还有个DRP (Dual Role port)，DRP可以做DFP也可以做UFP。当DPR接 到UFP，DRP转化为DFP。当DRP接到DFP，DRP转化为UFP。两个DRP接在一起，这时就是 任意一方为DFP，另一方为UFP。 在DFP的CC pin有上拉电阻Rp，在UFP有下拉电阻Rd。未连接时，DFP的VBUS是无输出 的。连接后，CC pin相连，DFP的CC pin会检测到UFP的下拉电阻Rd，说明连接上了， DFP就打开Vbus电源开关，输出电源给UFP。 而哪个CC pin（CC1，CC2）检测到下拉 电阻就确定接口插入的方向，顺便切换RX/TX。 电阻Rd=5.1KΩ，电阻Rp＝56KΩ，根据前面的图看到USB Type-C有几种供电模式，靠 什么来识别？就靠Rp/Rp电阻，电阻值不一样，CC pin检测到的电压就不一样，然后 来控制DFP端执行哪种供电模式。 需要注意的是，上图里画了两个CC，实际上在不含芯片的线缆里只有一根CC线。 含芯片的线缆也不是两根cc线，而是一根cc，一根Vconn，用来给线缆里的芯片供电 （3.3V或5V），这时就cc端没有下拉电阻Rd，而是下拉电阻Ra，800-1200欧。

The USB 2.0 Type-C plug is shown in Figure 3-9. The following design simplifications may be made when only USB 2.0 is supported:∙Only the contacts necessary to support USB PD and USB 2.0 are required in the plug.All other pin locations may be unpopulated. See Table 3-5. All contacts are required to be present in the mating interface of the USB Type-C receptacle connector.∙Unlike the USB Full-Featured Type-C plug, the internal EMC springs may be formed from the same strip as the signal, power, and ground contacts. The internal EMC springs contact the inner surface of the plug shell and mate with the receptacle EMC pads when the plug is seated in the receptacle.∙ A paddle card inside the plug may not be necessary if wires are directly attac hed to the contact pins.Figure 3-9 USB 2.0 Type-C Plug Interface Dimensions3.2.2Reference DesignsThis section provides reference designs for a few key features of the USB Type-C connector. The reference designs are provided as acceptable design examples. They are not normative.3.2.2.1Receptacle Mid-Plate (Informative)The signals between the top and bottom of the receptacle tongue are isolated by a mid-plate inside the tongue. Figure 3-10 shows a reference design of the mid-plate. It is important to pay attention to the following features of the middle plate:∙The distance between the signal contacts and the mid-plate should be accurately controlled since the variation of this distance may significantly impact impedance of the connector.∙The mid-plate in this particular design protrudes slightly beyond the front surface of the tongue. This is to protect the tongue front surface from damage caused by miss-insertion of small objects into the receptacle.∙The mid-plate is required to be directly connected to the PCB ground with at least two grounding points.∙The sides of the mid-plate mate with the plug side latches, making ground connections to reduce EMC. Proper surface finishes are necessary in the areaswhere the side latches and mid-plate connections occur.Figure 3-10 Reference Design of Receptacle Mid-Plate3.2.2.2Side Latch (informative)The side latches (retention latches) are located in the plug. Figure 3-11 shows a reference design of a blanked side latch. The plug side latches should contact the receptacle mid-plate to provide an additional ground return path.Figure 3-11 Reference Design of the Retention LatchFigure 3-12 Illustration of the Latch Soldered to the Paddle Card Ground3.2.2.3Internal EMI Springs and Pads (Informative)Figure 3-13 is a reference design of the internal EMC spring located inside the USB Full-Featured Type-C plug. Figure 3-14 is a reference design of the internal EMC spring located inside the USB 2.0 Type-C plug.Figure 3-13 Reference Design of the USB Full-Featured Type-C Plug Internal EMCSpringFigure 3-14 Reference Design of the USB 2.0 Type-C Plug Internal EMC SpringIt is critical that the internal EMC spring contacts the plug shell as close to the EMC spring mating interface as possible to minimize the length of the return path.The internal EMC pad (i.e., ground plate) shown in Figure 3-15 is inside the receptacle. It mates with the EMC spring in the plug. To provide an effective ground return, the EMC pads should have multiple connections with the receptacle shell.Figure 3-15 Reference Design of Internal EMC Pad3.2.2.4Optional External Receptacle EMC Springs (Informative)Some applications may use receptacles with EMC springs that contact the outside of the plug shell. Figure 3-16 shows a reference receptacle design with external EMC springs. The EMC spring contact landing zones for the fully mated condition are normative and defined in Section 3.2.1.Figure 3-16 Reference Design of a USB Type-C Receptacle with External EMC Springs。

USBUSB ,是英文Universal Serial BUS（通用串行总线）的缩写，而其中文简称为“通串线，是一个外部总线标准，用于规范电脑与外部设备的连接和通讯.是应用在PC领域的接口技术。

USB接口支持设备的即插即用和热插拔功能.USB是在1994年底由英特尔、康柏、IB M、Microsoft等多家公司联合提出的。

简述不过直到近期，它才得到广泛地应用。

从1994年11月11日发表了USB V0。

7版本以后,USB版本经历了多年的发展，到现在已经发展为3.0版本,成为目前电脑中的标准扩展接口.目前主板中主要是采用USB1.1和USB2。

0,各USB版本间能很好的兼容。

USB用一个4针（USB3.0标准为8针）插头作为标准插头，采用菊花链形式可以把所有的外设连接起来，最多可以连接127个外部设备，并且不会损失带宽。

USB需要主机硬件、操作系统和外设三个方面的支持才能工作。

目前的主板一般都采用支持USB功能的控制芯片组，主板上也安装有USB接口插座，而且除了背板的插座之外，主板上还预留有USB插针,可以通过连线接到机箱前面作为前置USB接口以方便使用（注意，在接线时要仔细阅读主板说明书并按图连接,千万不可接错而使设备损坏）。

而且USB接口还可以通过专门的USB连机线实现双机互连，并可以通过Hub扩展出更多的接口.USB具有传输速度快（USB1。

1是12Mbps,USB2。

0是480Mbps，USB3。

0是5 Gbps），使用方便，支持热插拔,连接灵活，独立供电等优点，可以连接鼠标、键盘、打印机、扫描仪、摄像头、闪存盘、MP3机、手机、数码相机、移动硬盘、外置光软驱、USB网卡、ADSL Modem、Cable Modem等，几乎所有的外部设备。

USB接口可用于连接多达127个外设，如鼠标、调制解调器和键盘等。

USB自从1996年推出后，已成功替代串口和并口,并成为当今个人电脑和大量智能设备的必配的接口之一。

Jay Tseng Fong-Jim WangRevision HistoryOctober 20, 2015Interface Specification1 IntroductionWith the continued success of USB Power Delivery, there exists a need to define a commoninterface from a USB Type-C TM Port Manager to a Simple USB Type-C Port Controller. This specification defines this interface.Figure 1-1 shows the interconnection between the USB Type-C Port Manager, TCPM, and three USB Type-C Port Controllers, TCPCs. One TCPM may be used to drive multiple TCPCs subjectbetween theFigure 1-1. USB Type-C Port Manager to USB Type-C Port Controller Interface1.1 PurposeThe USB Type-C Port Controller Interface, TCPCI, is the interface between a USB Type-C Port Manager and a USB Type-C Port Controller. This specification standardizes the communication between the USB Type-C Port Manager (TCPM) and the USB Type-C Port Controller (TCPC) while meeting the USB Type-C Power Delivery requirements.The goal of the USB Type-C Port Controller Interface (TCPCI) is to provide a defined interface between a TCPC and a TCPM in order to standardize and simplify USB Type-C Port Manager implementations.The TCPC is a functional block which encapsulates V BUS and V CONN power controls, USB Type-C CC logic, and the USB PD BMC physical layer and protocol layer other than the message creation.1.2 ScopeThis specification is intended as a supplement to USB 3.1, USB Type-C , and USB PDspecifications. It addresses only the elements required to implement and support the USB Type-C Port Controller.Normative information is provided to allow interoperability of components designed to this specification.

TCPC InterfaceThe USB Type-C Port Controller Interface, TCPCI, is the interface between a USB Type-C Port Manager and a USB Type-C Port Controller. The goal of the USB Type-C Port Controller Interface (TCPCI) is to provide a defined interface between a TCPC and a TCPM in order to standardize and simplify USB Type-C Port Manager implementations.The TCPC is a functional block which encapsulates V BUS and V CONN power controls, USB Type-C CC logic, and the USB PD BMC physical layer and protocol layer other than the message creation. The TCPC shall NOT include support for USB PD BFSK.3Type-C Port Controller RequirementsThis chapter describes the requirements of a USB Type-C Port Controller. The TCPC has three functions:∙USB Type-C Port Power Control for V BUS and V CONN (required)∙USB Type-C CC Control and sensing (required)∙USB PD Message delivery (required)∙Standard Inputs and Outputs are defined for simplified external interfacing (optional)The TCPC uses I2C to communicate with the TCPM. The TCPC is an I2C slave with Alert# signal for requesting attention.3.1Port Power Control for VBUS and VCONNA Source capable TCPC shall provide a register which allows the TCPM to control V BUS Sourcing. A Sink capable TCPC shall provide a register which allows the TCPM to ControlV BUS Sinking.To ensure safety in case the I2C interface fails, the TCPC that is sourcing V BUS higher than 5V shall autonomously stop sourcing V BUS if the Sink is detached.The TCPC shall implement a force discharge circuit. A low current bleed discharge may also be implemented. The force discharge is a larger current discharge used to discharge to below vSafe0V upon detecting a Disconnect per USB Type-C (exiting the Attached.SRC state). The discharge shall be available for both Source and Sink.A TCPC shall include monitoring for the presence of V BUS (VSafe5V, VSafe0V). The TCPC shall implement high and low voltage alarms if it Sinks or Sources voltage greater tha n VSafe5V.A Source or DRP TCPC shall include control for V CONN sourcing. A Sink TCPC shall include control for V CONN sourcing if V CONN Swap or Sink w/Accessory is supported. V CONN sourcing shall meet the tV CONN ON and tV CONN OFF timing requirement per USB Type-C.A TCPC shall implement low power states as defined in this specification.3.2USB CC LogicThe TCPC shall implement logic for controlling the CC pins on the USB Type-C Connector. The TCPC shall implement a method to control the Port Power Role and to report the state of the CC lines, Rp/Rd control, and CC sense/debounce/interrupt.3.3USB-PD Message DeliveryThe TCPC shall implement BMC encoding. The TCPC shall NOT include support for USB PD BFSK. The TCPC shall implement the portion of the Protocol layer in the USB PD specification as shown in Figure 3-2, and 3-3. The TCPC is opaque from a USB PD point of view. The TCPC sends and receives messages constructed in the TCPM and places them on the CC connections. The TCPC does not interpret the USB PD messages.The TCPC shall implement the entire USB PD PHY layer with BMC encoding. The TCPC shall implement a portion of the Transmit state machine.∙CRCReceiveTimer (PRL_Tx_wait_for_Phy_Response_state)∙RetryCounter (PRL_Tx_Check_RetryCounter State)∙MessageID is not checked in the TCPC when a non-GoodCRC message is received.Retried messages that are received are passed to the TCPM via I2C ∙Received GoodCRC must match the transmitted MessageID and SOP type before it is considered valid∙Two things allow the TCPM to track the MessageID even when asynchronous messages are receivedo If ALERT.ReceiveSOP*MessageStatus is not cleared when the TCPM requestsa TRANSMIT then the I2C command is NAK’d orTransmitSOP*MessageDiscarded bit in the ALERT register is asserted.o If a message is received before the TCPC has processed a transmit request, it asserts the TransmitSOP*MessageDiscarded bit in the ALERT register.∙BIST handling shall be as follows: Each incoming BIST message may be passed up to the policy engine as is any other incoming USB PD Message, or responded to with a GoodCRC without passing to the policy engine. The TCPC shall provide a mechanism to allow the policy engine to send a BIST Continuous Carrier Mode 2 message fortBistContMode.3.4Debug Accessory DetectionThe TCPC may implement autonomous detection of the Debug Accessory State (vRd/vRd) per USB Type-C. This allows the TCPC to indicate a vRd/vRd connection without TCPM involvement, and indicates this via the DebugAccessoryConnected# output andPOWER_STATUS.DebugAccessoryConnected. The TCPC performs autonomous detection of the Debug Accessory state if TCPC_CONTROL.DebugAccessoryControl=0b.The TCPM may control entry to the Debug Accessory Detected state by settingTCPC_CONTROL.DebugAccessoryControl=1b.The behavior in the Debug Accessory state is defined in USB Type-C in Appendix B.3.5 TCPC State-MachinesThis section describes the normative State-Machines for the TCPC. The informative TCPM State-Machines can be found in Appendix A.Figure 3-1. Rx State-Machine Implemented in TCPC1becomes idle again (see USB-PD specification). Two alternate allowable transitions are shown.2Messages do not include Hard Reset or Cable Reset signals or expected GoodCRC messages (GoodCRC messages are only expected after the TCPC PHY has received the tx message and the TCPC Tx state-machine is in the PRL_Tx_Wait_for_PHY_response state).3The TCPC may not discard the transmission if the received message is a Ping message.1The CRCReceiveTimer is only started after the PHY has sent the message. If the message is not sent due to a busy channel then the CRCReceiveTimer will not be started (see USB-PD Rev2.0 v1.1 Section 6.5.1).2This indication is sent by the PHY Layer when a message has been discarded due to V BUS or CC being busy, and after V BUS or CC becomes idle again (see USB-PD REv2.0 v1.1 Section 5.8). The CRCReceiveTimer is not running in this case since no message has been sent.Figure 3-2. Tx State-Machine Implemented in TCPCFigure 3-3. Hard Reset Transmission State-Machine implemented in the TCPC3.6USB Type-C Port Controller Requirements for Source, Sink, and DRP3.6.1Source RequirementsA TCPC, which supports Source port operation, is defined as follow:1.

A DRP TCPC shall provide a mechanism for detecting vSafe0V.4USB Type-C Port Controller InterfaceThe USB Type-C Port Controller Interface (TCPCI) is a low level interface which handles V BUS and V CONN power connections, CC communication and USB-PD message delivery through a simple register interface. Communication between the TCPC and the USB Type-C Port Manager (TCPM) is over an I2C bus.The TCPCI uses the I2C protocol with the following behaviors:1.The TCPM is the only master on the I2C bus.2.The TCPC is a slave device on the I2C bus.3.The TCPM designer must meet the I2C bus loading requirements when determiningthe maximum number of devices on the I2C bus.4.Each USB Type-C port has its own unique I2C slave address.

TheTCPM should assume the register information returned from a Write only register is not valid.12.The TCPC shall not NAK if the TCPM writes to a register or bit that is notimplemented or reserved.。

USB Type-C是什么？感谢把我给崩了的投递时间：2015-03-14 来源：三联北京时间3月10日凌晨，苹果在美国旧金山芳草地艺术中心发布了新款Macbook，它的轻薄给无数消费者留下了深刻的印象。

再一次，追求极致的苹果对 Macbook 12上的各种接口挥起了屠刀，在砍掉原有全部接口的情况下，向我们介绍了一种如 Lightning 接口般轻薄小巧的新型 USB 接口：USB Type-C。

那么问题来了，USB Type-C是什么?为什么苹果会选择 USB 而不是力推多年的Thunderbolt，USB Type-C是何方神圣?下面百事网小编为大家详细介绍下下。

USB Type-C是什么?USB Type-C简称为USB-C，它的诞生并不久远，早在13年12月，USB 3.0推广团队就已经公布了下一代USB Type-C连接器的渲染图，在2014年8月发布的USB 3.1标准中才刚刚定稿。

它是一种新型 USB 线缆及连接器的规范，定义了包括连接器、端口、容器和线缆等在内的一整套全新的USB物理规格。

USB Type-C是一种和iPhone手机中Lightning接口般轻薄小巧的新型USB接口，可以扩展成电源/USB传输/VGA或HDMI三个接口，通过适配器，还可以兼容USB3.0、USB2.0等上一代接口。

USB Type-C具有全新的接口尺寸和略显酷炫的名称，非常容易使第一次听到这个名词的消费者以为这是一种全新的USB标准，但实际上并不是。

USB Type-C 只是 USB 3.1 标准的一部分，而不是一个新的标准。

另外，需要说明的是，与常见的 USB 2.0 类似，USB 3.1 标准仍有Type-A(常见于电脑主机)和 Micro-B(常见于安卓手机)等接口，Type-C 并不是消费者享受 USB 3.1 高速数据传输的唯一选择。

苹果Mac 12单USB-C接口揭秘为什么USB组织需要推出一种新的物理接口规范呢?随着越来越多新型设备对于轻量化小型化的追求，传统 USB 接口的“庞大”尺寸已经很难满足设备生产厂商和消费者的需求。

新版USBType-C新规范出炉继电器USB Type-C接口有可能成为未来多数笔记本电脑、智能手机的唯一数据接口，但这些仅支持USB接口的设备仍必须与那些非USB接口的设备进行交互，比如显示器、电视机等。

因此，设计人员需要考虑如何在单个连接器中实现USB和其他高速接口的转换，其中涉及到切换引脚功能、提供诸如ESD的外部瞬变保护以及维护信号质量等问题。

USB Type-C标准通过定义备用模式(Alt Mode)来满足这些需求，这种方法能够动态地更改引脚的功能，从而支持非USB的数据传输协议。

本文对各类标准进行了介绍，有了这些标准，USB Type-C才能连接到HDMI或其他非USB形式的数据接口。

本文中还包含将HDMI备用模式增加到USB Type-C接口时需要考虑的主要问题。

USB规范介绍HDMI Forum于2016年底发布了USB Type-C备用模式规范，此最新版USB标准共包括以下三个部分：USB Type-C接口规范USB Type-C接口规范在我们所熟知的Type-A和Type-B规范基础上进行了大幅度的修改。

对于普通用户来说，有两点改动需要注意：Type-C 接口尺寸为8.3mmx2.5mm，较之USB Type-A和Type-B小了很多，但却包含24个引脚，之前的版本只有4个引脚。

Type-C接口支持正反逆插，这是因为Type-C接口采用了对称结构，无论哪一面在上，所有的信号引脚都处在相同的相对位置上。

USB Type-C还可以通过D+/D-和VBUS/GND引脚与传统的USB 2.0系统进行交互。

其引脚布局还包括其他两个规范中定义的新功能引脚(包括备用模式)。

图1显示的是Type-C接口标准和备用模式引脚映射。

USB3.1特有的TYPE-C数据线接口定义USB3.1特有的TYPE-C数据线接口定义TYPE-C数据线接口在之前USB3.1是啥这篇文章中，我们介绍了USB3.1与以往USB 版本速度上的区别。

今天重点介绍一下USB3.1特有的数据线接口USB TYPE-C接口。

USB Type-C接口，又称USB-C接口。

它是基于USB 3.1规范全新设计的连接器。

我们都知道苹果从在2012年发布iphone 5首次引入了Lightning数据线接口，其最大的特点是用户不再去区分手机数据线接口的正反面。

USB3.1的Type-C接口外观上最大特点也是数据线接口的上下端完全一致，用户也不必再去区分USB接口的正反面，如同苹果Lightning接口一样，两个方向都可以插入。

TYPE-C接口与Lightning接口的对比从上图中可以发现苹果数据线接口Lightning和USB Type-C数据线接口共同的特点是均不分正反面，Lightning接口我们可以认为它属于公头接口，Type-C接口属于母头接口。

通用性上Lightning接口只能用于苹果的产品，是苹果公司特有的数据线接口。

Type-C应用氛围更广，支持Type-C的数码产品均可使用。

Type-C数据线接口与其它USB接口的区别在以前关于USB2.0接口定义和USB3.0接口定义的文章中我们都介绍有USB的接口类型和USB封装，读者可详细了解。

这里重点介绍一下以往版本的中USB接口类型与Type-C接口的区别，从上图中可以发现USB2.0 接口规范中的Type-A、Type-B、mini-A、mini-B、Micro-A、Micro-B接口和USB3.0接口规范中的Type-B、Micro-B 接口都有一个共同的特点那就是防呆设计，而Type-C接口则不分正反面，USB3.1 Type-C的另一个大卖点就是对移动设备充电能力的的增强。

USB 3.1接口下的供电最高允许标准大幅提高到了20V/5A（仅限于Type-A/B），能够提供达100W的供电输出能力。

USBTYPEC拆解以及USB3.1规范详解USB全称为Universal Serial Bus，翻译为通用串行总线，是连接计算机系统与外部设备的一种串口总线标准，也是一种输入输出接口的技术规范，被广泛地应用于个人电脑和移动设备等信息通讯产品，并扩展至摄影器材、数字电视（机顶盒）、游戏机等其它相关领域。

随着IT行业不断进步，USB历经以下几个阶段：USB1.0：1.5Mbps(192KB/s)低速(Low-Speed)500mA，1996年1月；USB1.1：12Mbps(1.5MB/s)全速(Full-Speed)500mA，1998年9月；USB2.0：480Mbps(60MB/s)高速(High-Speed)500mA，2000年4月；USB3.0：5Gbps(640MB/s)超速(Super-Speed)900mA，2008年11月；USB3.1：10Gbps(1.25GB/s)超速加(SuperSpeed+)5A，2013年12月。

最新一代的USB 3.1 Gen2，传输速度为10Gbit/s，三段式电压5V/12V/20V，最大供电100W 。

而伴随USB3.1而来的C型USB接口：USB Type C大有一统消费电子接口的趋势，近期已占领各大品牌旗舰手机接口榜首。

一、USB Type C外观及引脚定义USB Type C接口以其纤薄、正反可插拔等诸多优势，得到了广泛运用，我们先看看USB Type C接头拆解图。

从上图拆解可见，USB Type C接口上下各有12个引脚，其引脚排列如下图：Type C母头引脚排列图Type C公头引脚排列图二、USB Type C三种工作模式USB3.1标准有三种工作模式：1：DRP。
