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.

XXX

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.
