NOTICE This is a production data sheet The specifi-
cations are subject to change without notice
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
Power and Frequency Requirements
The typical relationship between I_CC and the fre-
quency of operation F is as follows
I_CCtyp e 55a 5 F mA
where F is in MHz
When the frequency is reduced below the minimum
operating frequency specified in the AC Characteris-
tics table the internal states of the 80C187 may be-
come indeterminate The 80C187 clock cannot be
stopped otherwise I_CC would increase significantly
beyond what the equation above indicates
