WARNING Stressing the device beyond the ‘‘Absolute
Maximum Ratings’’ may cause permanent damage
These are stress ratings only Operation beyond the
‘‘Operating Conditions’’ is not recommended and ex-
tended exposure beyond the ‘‘Operating Conditions’’
may affect device reliability
When the frequency is reduced below the minumum
operating frequency specified in the AC Characteris-
tics table the internal states of the M80C287 may
become indeterminate The M80C287 clock cannot
be stopped otherwise ICC would increase signifi-
cantly beyond what the equation above indicates
