Notes:
1) Capacitive loading on ports 0 and 2 may cause spurious noise pulses to be superimposed on the
V
of ALE
and port 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 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
DD
specification when the address lines are stabilizing.
3) Power-down modes:
I
PD1
is measured under following conditions:
EA = Port 0 =
V
; RESET =
V
.; XTAL2 = XTAL4 = N.C.; XTAL1 = XTAL3 =
V
SS
;
V
AGND
=
V
SS
;
V
AREF
=
V
DD
; all other pins are disconnected.
Conditions for
I
and
I
are similar except that XTAL3 and XTAL4 have a valid input from the 32.768 KHz
crystal and the power supply limits.
4)
I
DD
(active mode) is measured with:
XTAL1 driven with
t
R
/
t
F
= 5 ns, 50% duty cycle ,
V
=
V
SS
+ 0.5 V,
V
=
V
– 0.5 V; XTAL2 = N.C.;
EA = Port0 = RESET =
V
DD
; all other pins are disconnected.
I
DD
would be slightly higher if a crystal oscillator
is used (approx. 1 mA)
5)
I
(idle mode) is measured with all output pins disconnected and with all peripherals disabled;
XTAL1 driven with
t
R
/
t
F
= 5 ns, 50% duty cycle,
V
IL
=
V
SS
+ 0.5 V,
V
IH
=
V
DD
– 0.5 V; XTAL2 = N.C.;
RESET = EA =
V
SS
; Port0 =
V
DD
; all other pins are disconnected; the microcontroller is put into idle mode by
software;
6)
I
DD
(active mode with slow-down) is measured with all output pins disconnected and with all peripherals
disabled; XTAL1 driven with
t
R
/
t
F
= 5 ns, 50% duty cycle,
V
IL
=
V
SS
+ 0.5 V,
V
IH
=
V
DD
– 0.5 V; XTAL2 = N.C.;
RESET = EA =
V
SS
; all other pins are disconnected; the microcontroller is put into slow-down mode by
software;
7)
I
DD
(idle mode with slow-down) is measured with all output pins disconnected and with all peripherals disabled;
XTAL1 driven with
t
R
/
t
= 5 ns, 50% duty cycle,
V
=
V
+ 0.5 V,
V
=
V
– 0.5 V; XTAL2 = N.C.;
RESET = EA =
V
SS
; Port0 =
V
DD
; all other pins are disconnected; the microcontroller is put into idle mode
with slow-down enabled by software;
8) Overload conditions under operating conditions occur if the voltage on the respective pin exceeds the
specified operating range (i.e.
V
OV
>
V
DD
+
0.5V or
V
OV
<
V
SS
–
0.5V). The absolute sum of input overload
currents on all port pins may not exceed
50 mA
. The supply voltage (
V
DD
and
V
SS
) must remain within the
specified limits.
9) Not 100% tested, guaranteed by design characterization
10) The typical
I
DD
values are periodically measured at
T
A
= + 25
°
C but not 100% tested.
11) The maximum
I
DD
values are measured under worst case conditions (
T
A
= 0
°
C or – 40
°
C and
V
DD
= 5.5 V)
12) Only valid in programming mode.
