1.1 Hardware

Figure 1–1 shows the equipment necessary to perform evaluation of the

TUSB3200EVM2.

Figure 1–1.TUSB3200EVM2 Design Platform Equipment

USB EVM2

The TUSB3200EVM2 hardware platform measures 6.0′′ X 5.5′′ (W ×L).

Throughout this document text inside of parentheses (ex.) represents

reference designators that identify components located on the

TUSB3200EVM2.

The hardware setup for the TUSB3200EVM2 can be accomplished by two

separate methods—EEPROM evaluation and in-circuit emulator (ICE)

evaluation.UseoftheEEPROMinstalledon theboardisrecommendedwhen

performing a quick initial check to verify if the board works properly. The

respective evaluation procedures are detailed in the following section.

1.1.1 EEPROM Evaluation (Internal Mode)

The TUSB3200EVM2 comes with a preprogrammed EEPROM. This

EEPROM is inserted in the 8-pin DIP socket. The jumper configuration for the

internalmode is listed inTable 1–1.Usethefollowingprocedurefor EEPROM

evaluation:

Set J8 to position 1–2 to bus-power the TUSB3200EVM2; set J8 to 2–3

to put the TUSB3200EVM2 in self-powered mode (a power supply is

required).

In self-powered mode, a single 9-V dc at 500-mA supply must be

connected to the power terminals 9V and ground (GND) of the

TUSB3200EVM2. Once the board is powered, GPIO, and the LEDs

should turn on, and the power drawn from the supply should not exceed

the USB specification of 500 mA.

Connect a USB cable from the root hub of the PC to type-B connector J1

on the EVM. This should start the USB enumeration on a host PC.

Enumeration signals that a USB (audio) device has been detected by the

should show up once the enumeration is complete. Double click this icon

to confirm that the USB is the preferred device for audio output; if not,

reconfigure the PC for USB audio output.

tor.

Attach emulator POD to TUSB3200EVM2 ICE Socket (J3). A 40-pin ex-

tension adapter may be required to allow enough clearance for access to

thebuttons,jumpers, and connectors. Pin 1 isdesignatedbyatriangleon

the opposite side of the J3 reference designator.
