Theory of Operation for USB DIG Platform Figure 2-3 shows the block diagram for the SM-USB-DIG platform. This platform is a general purpose data acquisition system that is used on several different Texas Instruments evaluation modules. The details of its operation are included in a separate document. The block diagram shown in Figure 2-3 is given as a brief overview of the platform. The brain of the SM-USB-DIG Platform is the TUSB3210. The TUSB3210 is an 8052 microcontroller that has a built in USB interface. The microcontroller receives information from the host computer that it interprets into power, I2C, SPI, and other digital I/O patterns. During the digital I/O transaction, the microcontroller reads the response of any device connected to the I/O interface. The response from the device is sent back to the PC where it is interpreted by the host computer.

In this tab you can read or set the ALERT and THERM limits for the TMP451. You can also set a temperature offset for the remote temperature sensor and enable a THERM hysteresis. Changing values in these controls automatically writes them. The Temperature Limits tab is shown in Figure 5-4. 16 TMP451EVM Software Overview SBOU131 - June 2013 Submit Documentation Feedback Copyright (c) 2013, Texas Instruments Incorporated Using the TMP451EVM Software www.ti.com Figure 5-4. Temperature Limits Tab 5.2.3 Configuration Register Tab The TMP451EVM software contains a tab for the configuration register, consecutive alert register, and status register. Changing values in this register automatically writes them. In the Configuration register the bit MASK1 masks the ALERT pin when enabled. R/S stands for RUN/STOP, when enabled this sets the TMP451 to standby. AL/TH stands for ALERT/THERM2. When this bit is enabled ALERT becomes a second THERM. The TRange bit switches the TMP451 from its normal temperature range of 0C-127C to its extended temperature range of -64C-191C. For the Consecutive Alert register the bit SMBus enables a 30-ms timeout while bits 1-3 determine how many out-of-limit measurements are needed to trigger an ALERT. Figure 5-5 shows the Configuration Register tab in the TMP451EVM software. See the data sheet for more information.
