1 What is the TUSB320 EVM?
The TUSB320 EVM is designed to evaluate TUSB320 devices. The EVM can be configured to operate in
DFP, UFP, or DRP mode via DIP switch selection and/or I2C control. All of the control inputs are also
selectable via DIP switch configuration. The TUSB320 devices can be used with legacy USB systems or
Type-C systems for evaluation purposes.

2 TUSB320 EVM Features
The EVM can be configured to be used for the evaluation of DFP, UFP, or DRP Type-C implementation.
The EVM can also be configured to operate in I2C or GPIO mode. Default configuration is I2C.
This section describes features provided by the EVM to enable users to evaluate Type-C implementations
in different modes of operation.
2.1 Power
The EVM can be powered by USB VBUS or 5-V to 5.5-V DC IN through a power jack J5 (2 mm positive
tip, 6.5 mm negative outer shield). The VBUS can be provided via a legacy connection or Type-C
connection. When the EVM operates in DFP mode, the VBUS is provided through micro-AB connector J6,
if the board is connected to a USB host or VBUS source. When the EVM operates in UFP mode, the
VBUS is provided through Type-C connector J1, if the board is connected to a USB host or VBUS source
through a Type-C cable. The 5-V DC IN (J5) can also be used to supply power if a stand-alone operation
is desired without connecting to a USB VBUS power source. If D9 is installed on the board, do not
connect the EVM to a USB Host system through the micro-AB USB2 connector(J6) at the same time 5 V
is supplied through 5-V DC IN J5 or Type-C Connector J7. Due to diode/IR drop in the test setup, the
VBUS on the connector may be below the desired level. The board is designed to take up to 5.5 V
through DC_5V IN or TP5(PWRIN) header for test purposes.
Test loops and headers to power rails and GND are provided for test purposes. Some power rails can be
isolated from the main power supply by removing ferrite beads or passive components. Refer to the
schematics for power rail connection details. Do not supply external power through the test headers/loops
unless the power rail has been isolated from other power sources. In normal operation, power must be
provided through the USB connectors or DC power barrel only: J7, J6, or J5.
2.2 VBUS
2.2.1 VBUSOff time
To meet the VBUSOff time of 650 ms, remove the 10-µF capacitor C1 . Current limiting can be reduced to
3 A–3.5 A by changing the R30 value to 47 kΩ.
2.2.2 VBUS Min Level
VBUS, provided on J1 or J6 may be lower than 4.75 V. For bus-powered devices to be attached to the
EVM for test purposes, TI recommends using a 5.5-V external power supply through J5 or TP5.

2.3 DIP Switch Setting
The DIP switch (SW1) is provided to configured the EVM in different modes of operation.
Table 1. DIP Switch Modes of Operation
Reference SW Control Default Description
Designator Function Switch Setting
SW1.1 EN# ON EN_N= High, if SW1.1 = OFF
EN_N = Low, if SW1.1 = ON
SW1.2 OUT2 OFF OUT2 = SCL with a pullup, if SW1.2 = OFF
OUT2 connected to LED, if SW1.2 = ON
SW1.3 OUT1 OFF OUT1 = SDA with a pullup, if SW1.2 = OFF
OUT2 connected to LED, if SW1.2 = ON
SW1.4 ADDR OFF For I2C mode of operation:
ADDR = High, if SW1.4 = OFF
ADDR = Low, if SW1.4 = ON
For GPIO mode of operation:
Remove R12 and SW1.4 = OFF
SW1.5 INT OFF INT = High, if SW1.5 = OFF
INT = OUT3, if SW1.5 = ON
SW1.6 320_VBUS OFF 320_VBUS = high/low or open if option resistors are populated.
Don’t care in normal operation.
SW1.7 PORT_H OFF PORT = Open, if SW1.7 = OFF
PORT = High, if SW1.7 = ON
SW1.8 PORT_L ON PORT = Open, if SW1.8 = OFF
PORT = Low, if SW1.8 = ON
2.4 I2C
The I2C bus can be accessed through a header: J1 or J2. 4.7-kΩpullups to 3.3 V are added on I2C SCL
and SDA. The ADDR pin can be pulled high or low through DIP SW configuration described in
Section 2.3,DIP Switch Setting. The ADDR pin determines the last bit of the TUSB320 I2C address to be
high or low. J1 is intended to match the Aardvark I2C programmer dongle pinout
2.5 LEDs
Several LEDs are provided for easier debug purposes.
Table 2. LEDs Debug Descriptions
Reference Designator LED Name Description
D1 OUT1 Valid only in GPIO mode. Illuminates if OUT1 pin driven low.
D2 OUT2 Valid only in GPIO mode. Illuminates if OUT2 pin driven low.
D3 OUT3 Valid only in GPIO mode. Illuminates if OUT3 pin driven low.
D4 320 ID Illuminates if the ID pin of TUSB320 is driven low.
D10 POWER Illuminates if 5-V power is available.
Note that the OUT1, OUT2, OUT3 LEDs are used in GPIO mode of operation. The DIP SW must be
configured accordingly to configure TUSB320 EVM in GPIO mode of operation. The LED may light up dim
even when OUT pins are not driven due to a pullup to 3.3 V.

3 TUSB320 EVM Configuration Examples
This section provides different configuration examples of the TUSB320 EVM: DRP, DFP or UFP operation.
The PORT pins and the I2C 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 I2C 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.
Figure 1 describes an example configuration using HD3SS2522 and TUSB320 EVMs. The HD3SS2522 is
a TI’s DFP CC controller compliant to USB Type-C spec v1.1.
Figure 1. Example Configuration Using HD3SS2522 and TUSB320 EVMs

SW1.8 PORT_L ON
2. Connect the HD3SS2522 EVM to a USB host.
3. Connect TUSB320 to the HD3SS2522 using a Type-C Cable. VBUS should be provided over the
Type-C cable connection. LED D10 should illuminate on the TUSB320 board. D3 and D4 should
illuminate on the HD3S2522 indicating an UFP connection. Please refer to the HD3SS2522 users
manual (SLLU215) for the details of the HD3SS2522 EVM operation.
4. USB devices plugged into the Micro AB USB receptacle(J6) of the TUSB320 UFP EVM should
enumerate at USB2 speed: HS, FS, or LS.

3.2 DFP Operation
The board can be configured to operate in DFP mode using the PORT pin on the board or I2C register
setting. If the PORT pin is to be used, the SW1.7 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 reprogram
unless it has been reconfigured for other modes of operation.
Figure 2 describes an example configuration using two TUSB320 EVMs: one configured as DFP, the other
configured as UFP. Refer to Section 3.1 for TUSB320 UFP EVM configuration.

2. Connect TUSB320 DFP EVM to a legacy USB host using a Type-A to micro-B cable via micro-AB
connector (J5) provided on board. The LED D10 should illuminate by the VBUS provided by the legacy
USB host over the Type-A to micro-B cable connection.
3. Connect TUSB320 UFP EVM to the TUSB320 DFP EVM using a Type-C Cable. The TUSB320 UFP
EVM should be powered by VBUS provided over the Type-C cable connection. The LED D10 on the
TUSB320 UFP EVM should also light up. Upon the Type-C cable, attach to the TUSB320 DFP EVM,
D4 should light up indicating the ID pin has been driven low from the TUSB320.
4. USB device plugged into the micro-AB USB receptacle(J6) of the TUSB320 UFP EVM should
enumerate at USB2 speed: HS, FS, or LS.

3.3 DRP Operation
The board can be configured to operate in DFP mode using the PORT pin on the board or I2C register
setting. If PORT pin is to be used, the SW1.7 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 reprogram unless it
has been reconfigured for other modes of operation. It is important that both SW settings are in the OFF
position to have the PORT input to the TUSB320 open.
Figure 3 illustrates an example configuration using HD3SS2522 and TUSB320 EVMs. The HD3SS2522 is
TI’s DFP CC controller, compliant to USB Type-C spec v1.1.

by the legacy USB host over the Type-A to micro-B cable connection.
3. Connect the TUSB320 UFP EVM to the TUSB320 DFP EVM using a Type-C cable. The TUSB320
UFP EVM should be powered by VBUS provided over the Type-C cable connection. The LED D10 on
the TUSB320 UFP EVM should also light up. Upon the Type-C cable attach to the TUSB320 DFP
EVM, D4 should light up indicating the ID pin has been driven low from the TUSB320.
4. The USB device plugged into the micro-AB USB receptacle (J6) of the TUSB320 UFP EVM should
enumerate at USB2 speed: HS, FS, or LS.
NOTE: Two TUSB320 EVMs can be used for DRP to DRP connection. In this configuration, it is not
recommended to connect the EVM to legacy USB systems as the role cannot be predicted
until both sides enters the attach state. This configuration can be used for evaluation
purposes with 5 V provided via DC IN (J5) on both boards.
