7 Chapter 1 Additional Hardware and Software The TUSB3200 EVM was designed for use with additional hardware and software. The emulator hardware should consist of a PC card, an interface cable, and an emulator pod. The pod may or may not have an extension module included. These components may or may not be sold independently depending on the vendor. The emulator software should include everything required to run the hardware. If programming in C++ instead of assembly code is desired, then a C++ to assembly code compiler is also a nice tool to add to the shopping list. It is recommended to check the compiler and the emulator for compatibility before making a selection. A USB cable is required to interface the TUSB3200 EVM to the PC. For an emulator from Nohau, visit the web site For an emulator from Phyton, visit the web site For a C compiler available from Keil, visit the web site Topic Page 1.1 Hardware Equipment Hardware Setup Additional Hardware and Software 1-1

8 Hardware Equipment 1.1 Hardware Equipment Figure 1 1. TUSB3200 Evaluation Platform Equipment ICE USB EVM POD 1.2 Hardware Setup The TUSB3200 EVM hardware platform is (W L). Throughout this document, text inside of parenthesis (ex.) represents reference designators found on the TUSB3200 EVM (see Figure 2 for a visual reference). First, install the hardware emulator card and the emulator software on the PC. Additionally, install the C++ compiler software, if available, on the same PC. Next, the emulator card must be interfaced to the emulator pod, which must have a 40-pin DIP connector attached. A 40-pin extension adapter may be required to allow enough clearance for access to the buttons, jumpers, and connectors. The emulator pod must be plugged into the TUSB3200 EVM at socket (J3). Make sure the orientation is correct. Pin 1 is designated by a square pad near the J3 reference designator. Look underneath the EVM platform to visually locate Pin 1. A USB cable is plugged into the root hub of the PC and connected to the TUSB3200 EVM type B connector (J1). Alternatively, the EVM platform may be evaluated with an EPROM (U4) versus the in-circuit emulator. A single 5-V dc power supply must be connected to the TUSB3200 EVM power terminals ground (P1B) and 5 V (P1A). If using the oscillator, be sure to plug it into the appropriate socket prior to powering up the EVM platform. The C-Port/I2C and GPIO ports use 20-pin and 26-pin IDC connectors respectively. An RS-232 connector is available for making a serial connection to a PC running a monitoring application. For convenience, a complete system is available on the EVM platform for evaluation. A microphone (J2) and two speakers (LOUT and ROUT) may be connected directly to the TUSB3200 EVM. Additionally, an analog line in (J6) source may also be plugged directly into the EVM platform. 1-2

11 Chapter 2 EVM Operation This chapter describes the setup and operation of the TUSB3200 evaluation module. Topic Page 2.1 TUSB3200 Setup Interfaces and Ports Power Supplies Light Emitting Diodes (LEDs) Jumpers and Switches Human Interface Device (HID) TIA/EIA-232-F (RS-232) Complete Analog Stage EPROM EVM Operation 2-1

12 TUSB3200 Setup 2.1 TUSB3200 Setup The TUSB3200 EVM allows development and evaluation of the TUSB3200 for controlling streams of data. The USB controller (U1) accepts USB data streams and generates output at the C-port, I 2 C port, and or GPIO port. The TUSB3200 data manual fully explains the configuration of the TUSB3200 to control the streaming data and set up the interface ports and registers. A standard USB cable is required to connect the EVM platform to a downstream port. The EVM uses a standard type-b connector. OSC1 may be used as a clock source for MCLKI. Set JP1 to position 1-2 for this function. Set JP3 to position 2-3 to send the MCLKO to the codec. For normal mode operation, set JP3 to position 2-3. This action disables the external interrupt signal to the TUSB3200. Note that an arrow always designates position 1 of any jumper. To use the in-circuit emulator, the TUSB3200 must be set to external mode. The TUSB3200 EVM board is shipped in internal mode. For internal mode, JP4 is open and JP15 is closed. To switch to external mode, simply move the jumper from JP15 to JP Interfaces and Ports The in-circuit emulator and the USB port interfaces are the only connections required. All other connections increase functionality allowing further development and evaluation. The USB connector has four pins defined as VBUS (pin 1), D+ (pin 2), D (pin 3), and GND (pin 4). The documentation for the in-circuit emulator provides the definition for the 40-pin interface. C-port/I2C (JB1) and GPIO port (JB2) are defined in Tables 2 1 and 2 2, respectively. These ports may be used as monitoring ports or to interface to another hardware platform. Typically, an oscilloscope or a logic analyzer is used in monitoring. An example of another hardware platform is a DSP EVM board. Table 2 1.

This supply must be regulated or come from a stable source, and must be capable of supplying 500 ma of current. An on board low dropout regulator is used to generate 3.3-V dc supply from the 5-V dc external supply. When the platform is powered, the red LED (LED1) is on. A diode provides protection in case the wrong polarity is applied to the power terminals. 2.4 Light Emitting Diodes (LEDs) A set of green and yellow LEDs are on the TUSB3200 EVM for quick and easy GPIO evaluation. The green LEDs are connected to port 1 bits 0 through 7 of the in-circuit emulator. These LEDs should only be evaluated in external mode. The yellow LEDs are connected to port 1 bits 0 through 7 and port 3 bits 0, 1, and 3-5 of the TUSB3200. These should only be evaluated in normal mode. Note that they illuminate in external mode but are not GPIO functions and should not be treated as such. 2.5 Jumpers and Switches Table 2 1 is provided to help setting up and configuring the EVM platform jumpers to the desired mode of operation. The switch descriptions are also defined in Table 2 1. EVM Operation 2-3

Switches S1A through S3A are connected to the TUSB3200, and switches S1B through S3B are connected to the in-circuit emulator. This allows HID control functions developed on the ICE to run from the EPROM in normal mode. 2-4

15 TIA/EIA-232-F (RS-232) 2.7 TIA/EIA-232-F (RS-232) An RS-232-like port provides for possible real-time monitoring applications. The port may be used in both internal and external modes. Set jumpers 6 and 7 according to table 3. Receive data (Rx) and transmit data (Tx) are the only two signals used for the serial interface. Electrical signal levels are RS-232 compliant but no handshake communication is present. 2.8 Complete Analog Stage A complete analog stage is provided on the EVM platform to eliminate the need for back-end development for evaluation purposes. The EVM platform contains: 20-dB gain monaural microphone preamplifier with a 3.5 mm input jack 1-V rms full-scale stereo line input with a 3.5 mm input jack Stereo headphone amplifier with a 3.5 mm output jack 2-watt audio-power-amplifier stereo differential output with RCA output jacks TLV320AIC27 AC 97 codec This allows connection of a microphone, an analog input source, and speakers or headphones. To use the analog stage, simply set jumpers JP8 through JP13 to position 2 3. This interfaces the TUSB3200 to the AC 97 codec. Note that this stage requires the proper firmware to work. 2.9 EPROM The EPROM is used in internal mode. The EPROM, although not required, is recommended to be 8K bytes in size to match the RAM memory size. An 8-pin DIP socket allows easy installation and removal of the EPROMs. In internal mode, the TUSB3200 automatically downloads the data from the EPROM into memory and begins executing the code. A hard reset (RESET) also causes the EPROM to load the TUSB3200. The EPROM is bypassed in external mode. EVM Operation 2-5
