USB-C: Everything you need to know!

USB-C: Everything you need to know

USB Type-C, which has a new interface size, Type-C follows the USB 3.1 standard and can be inserted and used very easily. And the USB-C interface is faster, reaching 5Gbps or 10Gbps, with 100W power supply capability.

Interface pin:

The following figure shows the interface pin diagram of TYPE-C. Each pin has a different function, and the center point is symmetrical so that it supports forward and reverse insertion.

TX/RX: two sets of differential signals for data transmission

CC1/CC2: Two key pins, a lot of functions

   Probe connection to distinguish between DFP and UFP

   Configure Vbus with USB Type-c and USB Power Delivery mode

   Configure Vconn. When there is a chip in the cable, a cc transmits a signal, and a cc becomes a power supply Vconn.

   Configure other modes, audio accessories, etc.

GND and VBus, each 4, so the transmission power is strong

D+ and D- are standard before being compatible with USB

USB Type-C has added new current detection and usage functions. Three new current modes are added: default USB power mode (500mA/900mA), 1.5A, 3.0A. Three current modes are transmitted and detected by CC pin. For DFPs that require broadcast current output capability, it is necessary to use different values of CC pull-up resistor Rp. For UFP, it is necessary to detect the voltage value on the CC pin to obtain the current output capability of the other DFP.

With the popularity of the USB Type-C interface, the Power Delivery (PD) protocol not only provides a unified fast charging standard for all electronic devices using the Type-C interface, including mobile phones, but also accelerates the development of battery direct charging solutions. popular.

Noun Note: DFP: Downstream Facing Port downstream port. Can be understood as Host, DFP provides VBUS, can also provide data. A typical DFP device is a power adapter because it always provides power. UFP: Upstream Facing Port) Upstream port. Can be understood as Device, UFP takes power from VBUS and can provide data. Typical devices are USB drives, which move hard drives because they are always read and taken from VBUS. DRP: Dual Role port dual role port. DRP: It can be used as DFP (Host) or UFP (Device), or it can be dynamically switched between DFP and UFP. A typical DRP device is a computer (the computer can act as a USB host or as a charged device).
