Overview

LM81 Serial Interface ACPI-Compatible Microprocessor System Hardware Monitor June 1999 LM81 Serial Interface ACPI-Compatible Microprocessor System Hardware Monitor General Description The LM81 is a highly integrated data acquisition system for hardware monitoring of servers, Personal Computers, or virtually any microprocessor-based system.
In a PC, the LM81 can be used to monitor power supply voltages, temperatures, and fan speeds.
Actual values for these inputs can be read at any time.
Programmable WATCHDOG™ limits in the LM81 activate a fully programmable and maskable interrupt system with two outputs (INT and T_CRIT_).
The LM81 has an on-chip digital output temperature sensor with 9-bit...
