TMP451EVM Hardware Setup
The TMP451EVM hardware consists of the SM-USB-DIG and TMP451EVM; these are easily connected
through a 10 pin board-to-board connector that should be attached to the SM-USB-DIG and TMP451EVM
PCBs. Once these two boards are connected, simply plug the USB device from the SM-USB-DIG into the
computer as shown in Figure 2-1.
Figure 2-1. TMP451EVM Hardware Setup
2.1 Theory of Operation for TMP451 Hardware
The TMP451EVM only requires the two-wire I2C™ lines (SDA and SCLK) and VDUT/GND to supply a
constant 3.3 V and power return as shown in Figure 2-2. The TMP451EVM also has test points to monitor
these signal lines, and ground in case the user may want to use their own signals or verify I2C
communications.
Figure 2-2. TMP451EVM Test Board Block Diagram
2.2 Signal Definitions of H1 (10-Pin Male Connector Socket)
Table 2-1 shows the pin out for the 10-Pin connector socket used to communicate between the
TMP451EVM and the SM-DIG. It should be noted that the TMP451EVM only uses the necessary I2C
communication lines (pins 1 and 3) and the VDUT and GND (pin 6 and 8) pins to issue commands to the
TMP451 sensors.

2.3 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.

TMP451EVM Hardware Overview
WARNING
Many of the components on the TMP451EVM are susceptible to
damage by electrostatic discharge (ESD). Customers are advised
to observe proper ESD handling precautions when unpacking and
handling the EVM, including the use of a grounded wrist strap at
an approved ESD workstation.
3.1 Connecting the Hardware
To connect the TMP451EVM and the SM-USB-DIG Platform together, gently slide the male and female
ends of the 10-pin connectors together. Make sure that the two connectors are completely pushed
together; loose connections may cause intermittent operation.
3.2 Connecting the USB Cable to the DIG
Figure 3-1 shows the typical response to connecting the SM-USB-DIG platform board to a PC USB port
for the first time. Typically, the computer responds with a Found New Hardware, USB device pop-up
dialog. The pop-up window then likely changes to Found New Hardware, USB Human Interface Device.
This pop-up indicates that the device is ready to be used. The SM-USB-DIG platform uses the human
interface device drivers that are part of the Microsoft Windows®operating system.
In some cases, the Windows Add Hardware Wizard is shown. If this prompt occurs, allow the system
device manager to install the human interface drivers by clicking Yes when requested to install drivers.
Windows confirms installation of the drivers with the message shown in Figure 3-2.

3.2.1 Optional 10-pin Connector Ribbon Extender
The TMP451EVM kit is shipped with an optional ribbon cable for extending the connection between the
SM-USB-DIG and the PCB. This can be useful if high temperature tests need to be run on the test board,
since the SM-USB-DIG is not rated for high temperatures. To connect the ribbon cable, attach the cable to
the EVM and SM-USB-DIG as shown in Figure 3-3.
Figure 3-3. 10-Pin Ribbon Cable Extender
3.3 TMP451EVM Features
This section describes some of the hardware features present on the TMP451EVM.
3.3.1 I2C Translator and Test Points
One of the features of the TMP451 is the ability of the part to be powered at 1.8 V while the
communication is still at 3.3 V. The TMP451EVM is equipped with an on board I2C level translator. This
allows the TMP451 and the I2C to be operated at 3.3 V or 1.8 V by shunting 3.3 V or 1.8 V on J3 and J2.
The I2C test points SDAB and SCLB are connected to the I2C line of the SM-USB-DIG and run to the input
of the level translator, U2. The I2C test points SDAA and SCLA are connected to the output of the level
translator, U2, and run to the clock and data lines of the TMP451.
3.3.2 Remote Temperature Terminal Block, J4
The TMP451EVM has a terminal block, J4, used for attaching a remote temperature sensor, in this case a
NPN transistor which is included in the kit. To connect the transistor, attach the base and collector to D+
and the emitter to D- as shown in Figure 3-4.

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 0°C–127°C
to its extended temperature range of –64°C–191°C. 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.
