| Time | Description | |
|---|---|---|
| Name | Type | Description |
| USB TYPE-C C | CONNECTOR INTER | RFACE |
| CC1/CC2 | I/O | Type-C connector Configuration Channel (CC) pins. Initially used to determine when an attach has occurred and what the orientation of the insertion is. Functionality after attach depends on mode of operation detected. Operating as a host: 1. Sets the allowable charging current for VBUS to be sensed by the attached device 2. Used to communicate with devices using USB BMC Power Delivery 3. Used to detect when a detach has occurred Operating as a device: 1. Indicates what the allowable sink current is from the attached host. Used to communicate with devices using USB BMC Power Delivery |
| GND | Ground | Ground |
| VBUS | Input | VBUS input pin for attach and detach detection when operating as an upstream facing port (Device). Expected to be an OVP protected input. |
| POWER INTER | RFACE | |
| VDD | Power | Input supply voltage. |
| VCONN | Power Switch | Regulated input to be switched to correct CC pin as VCONN to power USB3.1 full-featured cables and other accessories. |
| SIGNAL INTER | RFACE | |
| SCL | Input | I 2 C serial clock signal to be connected to the phone-based I 2 C master. |
| SDA | Open-Drain I/O | I 2 C serial data signal to be connected to the phone-based I 2 C master |
| INT_N | Open-Drain Output | Active LOW open drain interrupt output used to prompt the processor to read the I 2 C register bits |
CONFIGURATION CHANNEL SWITCH
The FUSB302B integrates the control and detection functionality required to implement a USB Type-C host, device or dual-role port including:
- Device Port Pull-Down (RD)
- Host Port Pull-Up (IP)
- VCONN Power Switch with OCP for Full-Featured USB3.1 Cables
- USB BMC Power Delivery Physical Layer
- Configuration Channel (CC) Threshold Comparators
Each CC pin contains a flexible switch matrix that allows the host software to control what type of Type-C port is implemented. The switches are shown in Figure 6.
