SNIS126A –MAY 2004–REVISED MARCH 2013  
LM90 ±3°C Accurate, Remote Diode and Local Digital Temperature Sensor with Two-Wire  
Interface  
Check for Samples: LM90

FEATURES  
DESCRIPTION  
The LM90 is an 11-bit digital temperature sensor with  
a 2-wire System Management Bus (SMBus) serial  
interface. The LM90 accurately measures its own  
temperature as well as the temperature of an external  
device, such as processor thermal diode or diode  
connected transistor such as the 2N3904. The  
temperature of any ASIC can be accurately  
determined using the LM90 as long as a dedicated  
diode (semiconductor junction) is available on the  
target die. The LM90 remote sensor accuracy of ±3°C  
is factory trimmed for the 1.008 typical non-ideality  
factor of the mobile Pentium III thermal diode. The  
LM90 has an Offset register to allow measuring other  
diodes without requiring continuous software  
management.

•
•
Diode Fault Detection Circuitry  
T_CRIT_A Output Useful for System Shutdown  
(Open Diode does not Activate T_CRIT_A)  
•
•
ALERT Output Supports SMBus 2.0 Protocol  
SMBus 2.0 Compatible Interface, Supports  
TIMEOUT  
Activation of the ALERT output occurs when any  
temperature goes outside a preprogrammed window  
set by the HIGH and LOW temperature limit registers  
or exceeds the T_CRIT temperature limit. Activation  
of the T_CRIT_A occurs when any temperature  
exceeds the T_CRIT programmed limit. The LM90 is  
pin and register compatible with the LM86, Analog  
Devices ADM1032 and Maxim MAX6657/8.
