GENERAL DESCRIPTION
The Am486DE2 microprocessor is an addition to the
AMD Am486 microprocessor family. The Am486DE2
enhances system performance by incorporating flexible
clock control and enhanced SMM.
The Am486DE2 CPU clock control feature permits the
CPU to be stopped under controlled conditions, allowing
reduced power consumption during system inactivity.
The SMM function is implemented with an industry-stan-
dard, two-pin interface.
