Recommended Connections
Power and ground connections must be made to
multiple VCC and VSS pins Every 80C186EA based
circuit board should contain separate power (VCC)
and ground (VSS) planes All VCC and VSS pins must
be connected to the appropriate plane Pins identi-
fied as ‘‘N C ’’ must not be connected in the system
Decoupling capacitors should be placed near the
processor The value and type of decoupling capac-
NOTICE This data sheet contains preliminary infor-
mation on new products in production It is valid for
the devices indicated in the revision history The
specifications 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
itors is application and board layout dependent The
processor can cause transient power surges when
its output buffers transition particularly when con-
nected to large capacitive loads
Always connect any unused input pins to an appro-
priate signal level In particular unused interrupt pins
(NMI INT3 0) should be connected to VSS to avoid
unwanted interrupts Leave any unused output pin
or any ‘‘N C ’’ pin unconnected
