The LM95235EVAL Evaluation Board is used together with the Texas Instruments SensorEval software (downloaded on the web), and with a USB cable (not provided in the kit), and with an external personal computer (PC). Power to the LM95235EVAL/NOPB Evaluation Board is provided by the +5 VDC line from the USB connection. No external power supply or signal sources are required for operation of the LM95235 evaluation board. Before connecting the PC to the LM95235EVAL evaluation board through the USB cable, the PC is first turned on and allowed to go through its boot-up procedure. The user installs and initiates the SensorEval software after downloading from http://www.ti.com/tool/sensoreval. August 2012 LM95235EVAL User’s Guide 1 After the SensorEval software is running, the user can connect the USB cable first to the computer and then to the LM95235EVAL/NOPB Evaluation Board. The PC should be able to recognize the board, and the user simply selects the LM95235 Evaluation Board radio button. The block diagram below describes the LM95235EVAL/NOPB Evaluation Board. The USB input provides the +5.0 VDC power to the board, which is regulated down to 3.3 VDC to power the IC’s. The EEPROM is programmed at the factory with a unique ID code for this particular board. When the USB cable is plugged in, the PC interrogates the USB devices and can identify this device as the LM95235 Evaluation Board. The microcontroller on the board provides the serial SMBus clock (SMBCLK), provides the SMBus data (SMBDAT) signal, and relays the information from the LM95235 to the PC via the USB lines. The block in the lower right of the Block Diagram shows the signals that are available to probe by the user for the LM95235 device on the board. 1.1 Block Diagram USB D+ USB Input USB DSMBCLK GND +5.0 VDC Microcontroller Circuitry SMBDAT EEPROM Circuit GND +3.3 VDC Voltage Regulator Circuit VDD SMBCLK SMBDAT U3 LM95235 T_Crit J5 GND OS/A0 J6 GND Figure 1: LM95235 Block Diagram 2 LM95235EVAL User’s Guide August 2012 The EVM contains one sensor which is attached to the EVM (See Table 1).
