DESCRIPTION
The LM71 is a low-power, high-resolution digital
temperature sensor with an SPI and MICROWIRE
compatible interface, available in the 5-pin SOT-23 or
the 6-pin WSON (no pull back) package. The host
can query the LM71 at any time to read temperature.
Its low operating current is useful in systems where
low power consumption is critical.
The LM71 has 13-bit plus sign temperature resolution
(0.03125°C per LSB) while operating over a
temperature range of −40°C to +150°C.
The LM71’s 2.65V to 5.5V supply voltage range, fast
conversion rate, low supply current, and simple SPI
interface make it ideal for a wide range of
applications. The LM71Q is available in the 5-lead
SOT-23 package only.

The LM71 will operate properly over the V supply voltage range of 2.65V to 5.5V.
Typicals are at TA = 25°C and represent most likely parametric norm.
Limits are ensured to AOQL (Average Outgoing Quality Level).
For best accuracy, minimize output loading. Higher sink currents can affect sensor accuracy with internal heating. This can cause an
error of 0.64°C at full rated sink current and saturation voltage based on junction-to-ambient thermal resistance.
This specification is provided only to indicate how often temperature data is updated. The LM71 can be read at any time without regard
to conversion state (and will yield last conversion result). A conversion in progress will not be interrupted. The output shift register will be
updated at the completion of the read and a new conversion restarted.

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.
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.
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.
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.
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.

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.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
