LM83  
Triple-Diode Input and Local Digital Temperature Sensor  
with Two-Wire Interface  
n On-board local temperature sensing  
General Description  
n SMBus and I2C compatible interface, supports  
The LM83 is a digital temperature sensor with a 2 wire serial  
SMBus 1.1 TIMEOUT  
interface that senses the voltage and thus the temperature of  
n Two interrupt outputs: INT and T_CRIT_A  
three remote diodes using a Delta-Sigma analog-to-digital  
converter with a digital over-temperature detector. The LM83  
accurately senses its own temperature as well as the tem-  
n Register readback capability  
n 7 bit plus sign temperature data format, 1 ˚C resolution  
perature of three external devices, such as Pentium II® Pro-  
cessors or diode connected 2N3904s. The temperature of  
any ASIC can be detected using the LM83 as long as a dedi-  
cated diode (semiconductor junction) is available on the die.  
Using the SMBus interface a host can access the LM83’s  
registers at any time. Activation of a T_CRIT_A output oc-  
curs when any temperature is greater than a programmable  
comparator limit, T_CRIT. Activation of an INT output occurs  
when any temperature is greater than its corresponding pro-  
grammable comparator HIGH limit.  
n 2 address select pins allow connection of 9 LM83s on a  
single bus

n Remote Diode Temp Accuracy (includes quantization

The host can program as well as read back the state of the  
T_CRIT register and the four T_HIGH registers. Three state  
logic inputs allow two pins (ADD0, ADD1) to select up to 9  
SMBus address locations for the LM83. The sensor powers  
up with default thresholds of 127˚C for T_CRIT and all  
T_HIGHs. The LM83 is pin for pin and register compatible  
with the LM84 as well as the Maxim MAX1617 and the Ana-  
log Devices ADM1021.
