9 Functional Description
The LM71 temperature sensor incorporates a temperature sensor and 13-bit plus sign ΔΣ ADC (Delta-Sigma
Analog-to-Digital Converter). Compatibility of the LM71's three wire serial interface with SPI and MICROWIRE
allows simple communications with common microcontrollers and processors. Shutdown mode can be used to
optimize current drain for different applications. A Manufacture's/Device ID register identifies the LM71 as TI
product.
9.1 POWER UP AND POWER DOWN
The LM71 always powers up in a known state. The power up default condition is continuous conversion mode.
Immediately after power up the LM71 will output an erroneous code until the first temperature conversion has
completed.
When the supply voltage is less than about 1.6V (typical), the LM71 is considered powered down. As the supply
voltage rises above the nominal 1.6V power up threshold, the internal registers are reset to the power up default
state described above.
9.2 SERIAL BUS INTERFACE
The LM71 operates as a slave and is compatible with SPI or MICROWIRE bus specifications. Data is clocked
out on the falling edge of the serial clock (SC), while data is clocked in on the rising edge of SC. A complete
transmit/receive communication will consist of 32 serial clocks. The first 16 clocks comprise the transmit phase of
communication, while the second 16 clocks are the receive phase.
When CS is high SI/O will be in TRI-STATE. Communication should be initiated by taking chip select (CS) low.
This should not be done when SC is changing from a low to high state. Once CS is low the serial I/O pin (SI/O)
will transmit the first bit of data. The master can then read this bit with the rising edge of SC. The remainder of
the data will be clocked out by the falling edge of SC. CS can be taken high at any time during the transmit
phase. If CS is brought low in the middle of a conversion the LM71 will complete the conversion and the output
shift register will be updated after CS is brought back high.
The receive phase of a communication starts after 16 SC periods. CS can remain low for 32 SC cycles. The
LM71 will read the data available on the SI/O line on the rising edge of the serial clock. Input data is to an 8-bit
shift register. The part will detect the last eight bits shifted into the register. The receive phase can last up to 16
SC periods. All ones must be shifted in order to place the part into shutdown. All zeros must be shifted in order to
place the LM71 into continuous conversion mode. Only the following codes should be transmitted to the LM71:
•
•
00 hex for continuous conversion
FF hex for shutdown
Another code may place the part into a test mode. Test modes are used by TI to thoroughly test the function of
the LM71 during production testing. Only eight bits have been defined above since only the last eight transmitted
are detected by the LM71, before CS is taken HIGH.
The following communication can be used to determine the Manufacturer's/Device ID and then immediately place
the part into continuous conversion mode. With CS continuously low:
•
•
•
•
•
Read 16 bits of temperature data
Write 16 bits of data commanding shutdown
Read 16 bits of Manufacture's/Device ID data
Write 8 to 16 bits of data commanding Conversion Mode
Take CS HIGH.
Note that 300 ms will have to pass for a conversion to complete before the LM71 actually transmits temperature
data.

The first data byte is the most significant byte with most significant bit first, permitting only as much data as
necessary to be read to determine temperature condition. For instance, if the first four bits of the temperature
data indicate an overtemperature condition, the host processor could immediately take action to remedy the
excessive temperatures.
9.4 SHUTDOWN MODE/MANUFACTURER'S ID
Shutdown mode is enabled by writing XX FF to the LM71 as shown in Figure 13. The serial bus is still active
when the LM71 is in shutdown. When in shutdown mode the LM71 always will output 1000 0000 0000 1111. This
is the manufacturer's/Device ID information. The first 5-bits of the field (1000 0XXX) are reserved for
manufacturer's ID.
9.5 INTERNAL REGISTER STRUCTURE
The LM71 has three registers, the temperature register, the configuration register and the manufacturer's/device
identification register. The temperature and manufacturer's/device identification registers are read only. The
configuration register is write only.

LM71 will stop responding as described. These test modes are to be used for TI production testing only. See

9.7 Application Hints
To get the expected results when measuring temperature with an integrated circuit temperature sensor like the
LM71, it is important to understand that the sensor measures its own die temperature. For the LM71, the best
thermal path between the die and the outside world is through the LM71's pins. In the SOT-23 package, all the
pins on the LM71 will have an equal effect on the die temperature. Because the pins represent a good thermal
path to the LM71 die, the LM71 will provide an accurate measurement of the temperature of the printed circuit
board on which it is mounted. There is a less efficient thermal path between the plastic package and the LM71
die. If the ambient air temperature is significantly different from the printed circuit board temperature, it will have
a small effect on the measured temperature.
In probe-type applications, the LM71 can be mounted inside a sealed-end metal tube, and can then be dipped
into a bath or screwed into a threaded hole in a tank. As with any IC, the LM71 and accompanying wiring and
circuits must be kept insulated and dry, to avoid leakage and corrosion. This is especially true if the circuit may
operate at cold temperatures where condensation can occur. Printed-circuit coatings and varnishes such as
Humiseal and epoxy paints or dips are often used to insure that moisture cannot corrode the LM71 or its
connections.
