0.25°C Temperature Resolution.  
The LM70 is a temperature sensor, Delta-Sigma  
analog-to-digital converter with an SPI and  
MICROWIRE compatible interface available in WSON  
and VSSOP 8-pin packages. The host can query the  
LM70 at any time to read temperature. A shutdown  
mode decreases power consumption to less than 10  
µA. This mode is useful in systems where low  
average power consumption is critical.

SNIS112G JUNE 2000REVISED MARCH 2013  
FUNCTIONAL DESCRIPTION  
The LM70 temperature sensor incorporates a band-gap type temperature sensor and 10-bit plus sign ΔΣ ADC  
(Delta-Sigma Analog-to-Digital Converter). Compatibility of the LM70'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 ID register identifies the LM70 as a  
TI product.  
POWER UP AND POWER DOWN  
The LM70 always powers up in a known state. The power up default condition is continuous conversion mode.  
Immediatly after power up the LM70 will output an erroneous code until the first temperature conversion has  
completed.  
When the supply voltage is less than about 1.6V (typical), the LM70 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 LM70 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 TRISTATE. 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. Once the 14 bits of data (one sign bit, ten temperature bits  
and 3 high bits) are transmitted the SI/O line will go into TRI-STATE. CS can be taken high at any time during  
the transmit phase. If CS is brought low in the middle of a conversion the LM70 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  
LM70 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. A zero in any location will take the  
LM70 out of shutdown. The following codes only should be transmitted to the LM70:  
00 hex (normal operation)  
01 hex (normal operation)  
03 hex (normal operation)  
07 hex (normal operation)  
0F hex (normal operation)  
1F hex (normal operation)  
3F hex(normal operation)  
7F hex(normal operation)  
FF hex (Shutdown, transmit manufacturer's ID)  
any others may place the part into a Test Mode. Test Modes are used by TI to thoroughly test the function of the  
LM70 during production testing. Only eight bits have been defined above since only the last eight transmitted,  
before CS is taken HIGH, are detected by the LM70  
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: The last two bits are TRI-STATE and depicted as one in the table.  
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 LM70 as shown in Figure 14c. and discussed in Section 1.2.  
The serial bus is still active when the LM70 is in shutdown. Current draw drops to less than 10 µA between serial  
communications. When in shutdown mode the LM70 always will output 1000 0001 0000 00XX. This is the  
manufacturer's ID/Device ID information. The first 5-bits of the field (1000 0XXX) are reserved for manufacturer's  
ID.  
INTERNAL REGISTER STRUCTURE  
The LM70 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  
LM70, it is important to understand that the sensor measures its own die temperature. For the LM70, the best  
thermal path between the die and the outside world is through the LM70's pins. In the VSSOP-8 package the  
ground pin is connected to the back side of the LM70 die and thus has the most effect on the die temperature.  
Although the other pins will also have some effect on the LM70die temperature and therefore should not be  
discounted. The LM70 will provide an accurate measurement of the temperature of the printed circuit board on  
which it is mounted, because the pins represent a good thermal path to the die. A less efficient thermal path  
exists between the plastic package and the LM70 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 LM70 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 LM70 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 LM70 or its  
connections.

(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability  
information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that  
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between  
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight  
in homogeneous material)  
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

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.
