1Introduction
PI5USB30213A is a dual differential channel bi-directional Mux/Demux switch with plug-in detector for USB 3.1
Type-C connector applications.
PI5USB30213A is designed for USB 3.1 Gen2 (10 Gbps) application.
The device includes:
1) The Plug-in Detector for Type-C connector (CC Sensing)
a) Supports Source/Sink/DRP/Try.SRC DRP/Try.SNK DRP
2) Integrated 2:1 USB3.0 Mux/DeMux
a) Auto-configure ports orientation through CC Sensing
3) Integrated VCONN switch to power active cable
PI5USB30213A detects the plug-in orientation of the cable at a Type-C connector and switches between the USB
controller and the new Type-C connector. It supports Host(Source/DFP) mode, Device(Sink/UFP) mode, Dual Role
Port(DRP), Try.SRC DRP and Try.SNK DRP with automatic configuration based on the voltage levels detected on CC
pins. It offers excellent signal integrity for high-speed signals at low power dissipation. PI5USB30213A enters disabled
state when ENB pin is pulled up to VDD through an internal resistor.
PI5USB30213A supports both pin and I2C control base on ADDR pin setting. It allows the system choose between pin
control and I2C control mode. In pin control mode, the PORT input pin determines the port setting in which Source(DFP)
only mode, Sink(UFP) only mode or Try.SNK DRP can be selected. Enabling I2C control mode allows higher flexibility for
port control and communications through registers read/write in PI5USB30213A. There is also flexibility to support Default,
1.5A and 3A current modes. An interrupt signal for indicating changes with the I2C registers is sent to the master to notify
the system any change in the Type-C connector while in parallel the system can still monitor ID pin.
This user manual describes the components and the usage of PI5USB30213A Demo Board Rev.B.
2Overview
Figure 1 is the block diagram of Diodes PI5USB30213A demo board and figure 2 shows the demo board layout. A USB-C
cable can be connected between the USB-C receptacle connector (J1) on PI5USB30213A demo board and another USB-
C device. A USB-C to USB-A cable can be connected between J1 and a USB host, such as PC. A USB-C to USB-A
receptacle adapter can be connected between J1 and a USB device, such as USB flash drive. One USB3 micro-AB
receptacle (J2) is used to connect mobile phones/notebook/tablet/PC to transmit USB3 data to/from J1.
Slide switch at reference SW1 is used to set control mode (GPIO/I2C) and operating mode (Source/Sink/DRP) of
PI5USB30213A and LED indicator to SDA/SCL/INTB/ID pins of PI5USB30213A. The processor can connect to
SDA/SCL/INTB/ID pins through pin header JP18/JP17/JP15 or Test Header J3.
+5V can be employed to the demo board via 5VPW header pin or mini-B receptacle (J4).
VBUS of Type-C connector can be source from on-board VBUS switch via JP4.
