Microprocessor System Hardware Monitor - National SemiconductorThe LM79 is a highly integrated Data Acquisition system for
hardware monitoring of servers, Personal Computers, or
virtually any Microprocessor based system. In a PC, the
LM79 CAN be used to monitor power supply voltages, tem-
peratures, and fan speeds. Actual values for these inputs
CAN be read at any time, and programmable WATCHDOG
limits in the LM79 activate a fully programmable and
maskable interrupt system with two outputs.
The LM79 has an on-chip Temperature Sensor 5 positive
Analog inputs, two inverting inputs (for monitoring negative
voltages), and an 8-bit ADC An input is provided for the
overtemperature outputs of additional Temperature Sensors
and this is linked to the interrupt system. The LM79 provides
inputs for three fan tachometer outputs. Additional inputs are
provided for Chassis Intrusion detection circuits, 5 VID moni-
tor inputs, and chainable interrupt. The LM79 provides both
ISA and Serial Bus Interfaces A 32-byte auto-increment
RAM is provided for POST (Power On Self Test) code stor-
age. By National Semiconductor Corporation
