Note 1 : ICC is measured with all output pins
disconnected ; XTAL1 driven with TCLCH, TCHCL =
5 ns, VIL = VSS + .5 V, VIH = VCC –.5 V ; XTAL2
N.C. ; EA = RST = Port 0 = VCC. ICC would be slighty
higher if a crystal oscillator used.
Idle ICC is measured with all output pins disconnected ;
XTAL1 driven with TCLCH, TCHCL = 5 ns, VIL =
VSS + 5 V, VIH = VCC –.5 V ; XTAL2 N.C ; Port 0 =
VCC ; EA = RST = VSS.
Power Down ICC is measured with all output pins
disconnected ; EA = PORT 0 = VCC ; XTAL2 N.C. ;
RST = VSS.
Note 2 : Capacitance loading on Ports 0 and 2 may cause
spurious noise pulses to be superimposed on the VOLS of
ALE and Ports 1 and 3. The noise is due to external bus
capacitance discharging into the Port 0 and Port 2 pins
when these pins make 1 to 0 transitions during bus
operations. In the worst cases (capacitive loading 100
pF), the noise pulse on the ALE line may exceed 0.45 V
may exceed 0,45 V with maxi VOL peak 0.6 V. A Schmitt
Trigger use is not necessary.
