TUSB320-LA-EVM and TUSB320-HA-EVM Configuration Examples
This section provides different configuration examples of the TUSB320-LA-EVM and TUSB320-HA-EVM:
DRP, DFP, or UFP operation. The PORT pins and the I
2
C must be programmed for the corresponding
mode of operation. No external 5-V DC IN is needed unless the board is to operate standalone without
any connections to the USB upstream or downstream port.
3.1
UFP Operation
The board can be configured to operate in UFP mode using the PORT pin on the board or I
2
C register
setting. If the PORT pin is to be used, SW1.8 must be switched ON and the Mode_Select bits at addr0x0A
bit 5:4 must be set to 00b. The Mode_Select is 00b by default, so there is no need to re-program unless it
has been reconfigured for other modes of operation.
describes an example configuration using HD3SS2522 and TUSB320-xA-EVM. The HD3SS2522
is a TI DFP CC controller, compliant to USB Type-C spec v1.1.

2. Connect the HD3SS2522 EVM to a USB host.
3. Connect TUSB320LA/HA to the HD3SS2522 using a Type-C Cable. VBUS should be provided over
the Type-C cable connection. LED D10 should illuminate on the TUSB320LA/HA board. D3 and D4
should illuminate on the HD3S2522 indicating an UFP connection. Refer to the HD3SS2522 users
manual (
) for the details of the HD3SS2522 EVM operation.
4. USB devices plugged into the Micro AB USB receptacle (J6) of the TUSB320LA/HA UFP EVM should
enumerate at USB2 speed: HS, FS, or LS.
