Chapter 1 Equipment This user’s guide describes the setup and operation of the TUSB3200EVM2 platform. This PCB contains two main active parts: TUSB3200A STC (TI USB streaming controller) and crystal CS4228 codec. This PCB is referred to as the TUSB3200EVM2 from this point on. Familiarity with emulator hardware and software is required and assumed throughout this user’s guide.
EEPROM is inserted in the 8-pin DIP socket. The jumper configuration for the internal mode is listed in Table 1–1. Use the following procedure for 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).
Install the emulator. Refer to the respective ICE user’s guide for the emula- 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 the buttons, jumpers, and connectors. Pin 1 is designated by a triangle on the opposite side of the J3 reference designator.

EVM board and another end of the cable to a PC root port. 2.4 Light Emitting Diode (LED) A set of green and yellow LEDs is installed on the TUSB3200EVM2 board for quick and easy GPIO evaluation. The green LEDs are connected to port 1 bits 0 through 7 of the in-circuit emulator for external mode.
2.7 EEPROM The EEPROM is used to set up the TUSB3200EVM2. The EEPROM is recommended to be 8K bytes to match the RAM memory size. Firmware for the TUSB3200EVM2 must be loaded for correct operation. An 8-pin DIP socket allows easy installation and removal of the EEPROM.
