3.2.2.24. USB

3.2.2.24.1. Introduction

The USB subsystem has a SuperSpeed (SS) USB3.1 Gen1 Dual-Role-Device (DRD) controller with on-chip SS (USB3.1 Gen1) PHY and HS/FS/LS (USB2.0) PHY.

Note

LowSpeed (LS) is only supported in host mode.

3.2.2.24.2. TI SoC Integration

The USB subsystem is integrated in TI J784S4 devices.

3.2.2.24.3. EVM

The following diagram depicts USB integration in J784S4 EVM.

The EVM supports one USB3.1 Gen1 Type C interface, which can function as DFP, UFP, or DRP.

Note

The Type-C config DIP switch (SW2) must be set for DRP (Dual-role-Port) operation. SW2.3 = ON, SW2.4 = OFF.

The EVM supports two USB2.0 Type A interfaces via an on-board USB hub. These ports can only function as Host. The processor supports a single USB interface. Therefore, the user must configure for either the USB3.1 Type C interface or the USB2.0 Type A interface. Both cannot be operated simultaneously.
