Power Supply Current
1) Capacitive loading on ports 0 and 2 may cause spurious noise pulses to be superimposed on the
V
OL
of ALE
and ports1, 3, 4, and 5. 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 operation. In the worst case (capacitive loading > 100 pF),
the noise pulse on ALE line may exceed 0.8 V. In such cases it may be desirable to qualify ALE with a schmitt-
trigger, or use an address latch with a schmitt-trigger strobe input.
2) Capacitive loading on ports 0 and 2 may cause the
V
OH
on ALE and PSEN to momentarily fall below the
0.9
V
CC
specification when the address lines are stabilizing.
3)
I
PD
(power-down mode) is measured under following conditions:
EA = Port 0 = Port 6 =
V
CC
; RESET =
V
CC
; XTAL1 = N.C.; PE = XTAL2 =
V
SS
;
V

AREF
=
V
CC
; all
other pins are disconnected. The typical
I
PD
current is measured at
V
CC
= 5 V.
4)
I
CC
(active mode) is measured with:
XTAL2 driven with
t
CLCH
,
t
CHCL
= 5 ns ,
V
IL
=
V
SS
+ 0.5 V,
V
IH
=
V
CC
– 0.5 V; XTAL1 = N.C.;
EA = Port 0 = Port 6 =
V
CC
; RESET =
V
SS
; all other pins are disconnected.
5)
I
CC
(idle mode) is measured with all output pins disconnected and with all peripherals disabled;
XTAL2 driven with
t
CLCH
,
t
CHCL
= 5 ns,
V
IL
=
V
SS
+ 0.5 V,
V
IH
=
V
CC
– 0.5 V; XTAL1 = N.C.;
EA = Port 0 = Port 6 =
V
CC
; RESET =
V
CC
; all other pins are disconnected;
6)
I
CC
(active mode with slow-down mode) is measured : TBD
7)
I
CC
(active mode with slow-down mode) is measured : TBD
8) Overload conditions occur if the standard operating conditions are exceeded, ie. the voltage on any pin
exceeds the specified range (i.e.
V
OV
>
V
CC
+ 0.5 V or
V
OV
<
V
SS
- 0.5 V). The supply voltage
V
CC
and
V
SS
must
remain within the specified limits. The absolute sum of input currents on all port pins may not exceed 50 mA.
9) Not 100% tested, guaranteed by design characterization
10)The typical
I
CC
values are periodically measured at
T
A
= +25
°
C but not 100% tested.
