Note 11:
All parameters apply to both commercial and industrial temperature operation unless otherwise noted. The value tMCS 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. All signals characterized with load capacitance of 80pF except Port 0, ALE,
PSEN, RD, and WR with 100pF.
Interfacing to memory devices with float times (turn off times) over 25ns can cause bus contention. This does not damage the
parts, but causes an increase in operating current. Specifications assume a 50% duty cycle for the oscillator. Port 2 and ALE timing
changes in relation to duty cycle variation. 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. AC timing is characterized and guaranteed by design but is not production tested.
