FEATURES  
P RO D UCT D ESCRIP TIO N  
Six Direct Voltage Measurem ent Inputs (Including Tw o  
Processor Core Voltages) w ith On-Chip Attenuators  
On-Chip Tem perature Sensor  
T he ADM9240 is a complete system hardware monitor for  
microprocessor-based systems, providing measurement and  
limit comparison of up to four power supplies and two proces-  
sor core voltages, plus temperature, two fan speeds and chassis  
intrusion. Measured values can be read out via an I2C-compat-  
ible serial System Management Bus, and values for limit com-  
parisons can be programmed in over the same serial bus. T he  
high speed successive approximation ADC allows frequent  
sampling of all analog channels to ensure a fast interrupt  
response to any out-of-limit measurement.  
Five Digital Inputs for VID Bits  
Fully Supports Intel’s LANDesk Client Manager (LDCM)  
Register-Com patible w ith LM7x Products  
Tw o Fan Speed Monitoring Inputs  
I2C® Com patible System Managem ent Bus (SMBus)  
Chassis Intrusion Detect  
Interrupt Output  
Program m able RESET I/ O Pin  
Shutdow n Mode to Minim ize Pow er Consum ption  
Lim it Com parison of all Monitored Values  
T he ADM9240’s 2.85 V to 5.75 V supply voltage range, low  
supply current and I2C compatible interface, make it ideal for a  
wide range of applications. T hese include hardware monitoring  
and protection applications in personal computers, electronic  
test equipment and office electronics.
