NOTES FOR AC ELECTRICAL CHARACTERISTICS:
1.
All parameters apply to both commercial and industrial temperature operation unless otherwise noted.
2.
The value t
MCS
is a function of the machine cycle clock in terms of the processor’s input clock
frequency. These relationships are described in the “Stretch Value Timing” table.
3.
All signals characterized with load capacitance of 80 pF except Port 0, ALE,
PSEN
,
RD
and
WR
with 100 pF.
4.
Interfacing to memory devices with float times (turn off times) over 25 ns may cause bus contention.
This will not damage the parts, but will cause an increase in operating current.
5.
Specifications assume a 50% duty cycle for the oscillator. Port 2 and ALE timing will change in
relation to duty cycle variation.
6.
Some AC timing characteristic drawings contain references to the CLK signal. This waveform is
provided to assist in determining the relative occurrence of events, and cannot be used to determine
the timing of signals relative to the external clock.
