ADM1023
ACPI‐Compliant, High
Accuracy Microprocessor
System Temperature Monitor
The ADM1023 is a 2-channel digital thermometer and
under/overtemperature alarm for use in personal computers and other
systems requiring thermal monitoring and management. Optimized
for the Pentium ? III, the higher accuracy allows systems designers to
safely reduce temperature guard banding and increase system
performance. The device can measure the temperature of a
microprocessor using a diode-connected PNP transistor, which may be
provided on-chip with the Pentium ? III or similar processors; or it can
be a low-cost, discrete NPN/PNP device such as the 2N3904/2N3906.
A novel measurement technique cancels out the absolute value of the
transistor ’s base emitter voltage so that no calibration is required. The
second measurement channel measures the output of an on-chip

temperature sensor to monitor the temperature of the device and its
environment.
The ADM1023 communicates over a 2-wire serial interface
compatible with SMBus standards. Under/overtemperature limits can
be programmed into the device over the serial bus, and an ALERT
output signals when the on-chip or remote temperature is out of range.
This output can be used as an interrupt or as an SMBus ALERT.
