RECOMMENDED CONNECTIONS

Power and ground connections must be made to

multiple VCC and VSS pins Every M80C186EB-

based circuit board should include separate power

(VCC) and ground (VSS) planes Every VCC pin must

be connected to the power plane and every VSS pin

must be connected to the ground plane Pins identi-

fied as ‘‘NC’’ must not be connected in the system

Liberal decoupling capacitance should be placed

near the M80C186EB The processor can cause

transient power surges when its output buffers tran-

sition particularly when connected to large capaci-

tive loads

Low inductance capacitors and interconnects are

recommended for best high frequency electrical per-

formance Inductance is reduced by placing the de-

coupling capacitors as close as possible to the

M80C186EB VCC and VSS package pins

Always connect any unused input to an appropriate

signal level In particular unused interrupt inputs

(INT04) should be connected to VCC through a pull-

up resistor (in the range of 50 KX) Leave any un-

used output pin or any NC pin unconnected
