Notes
:
1) Capacitive loading on ports 0 and 2 may cause spurious noise pulses to be superimposed on the
V
OL
of ALE
and port 1, 3, 4, 5, 6, and 9. 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/RDF 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 = RESET =
V
CC
; Port0 = Port7 = Port8 =
V
CC
; XTAL1 = N.C.; XTAL2 =
V
SS
; PE/SWD = OWE =
V
SS
;
HWDP =
V
CC
;
V
AREF
=
V
CC
;
V
AGND
=
V
SS
; all other pins are disconnected.
Hardware power down mode current (
I
PD
) is measured with OWE =
V
CC
or
V
SS
.
4)
I
CC
(active mode) is measured with:
XTAL2 driven with
t
R
/
t
F
= 5 ns ,
V
IL
=
V
SS
+ 0.5 V,
V
IH
=
V
CC
– 0.5 V; XTAL1 = N.C.; EA = PE/SWD=
V
CC
;
Port0 = Port7 = Port8 =
V
CC
; HWPD =
V
CC
; RESET =
V
SS
; all other pins are disconnected.
I
CC
would be
slightly higher if a crystal oscillator is used.
5)
I
CC
(idle mode) is measured with all output pins disconnected and with all peripherals disabled;
XTAL2 driven with
t
R
/
t
F
= 5 ns,
V
IL
=
V
SS
+ 0.5 V,
V
IH
=
V
CC
– 0.5 V; XTAL1 = N.C.; RESET =
V
CC
;
HWPD =
V
CC
; Port0 = Port7 = Port8 =
V
CC
; EA = PE/SWD =
V
SS
; all other pins are disconnected;
6)
I
CC
(slow down mode) is measured with all output pins disconnected and with all peripherals disabled;
XTAL2 driven with
t
R
/
t
F
= 5 ns,
V
IL
=
V
SS
+ 0.5 V,
V
IH
=
V
CC
– 0.5 V; XTAL1 = N.C.; RESET =
V
CC
;
HWPD =
V
CC
; Port7 = Port8 =
V
CC
; EA = PE/SWD =
V
SS
; all other pins are disconnected;
7) Input leakage current for port 0 is measured with RESET =
V
CC
.
8)
I
CC max
at other frequencies is given by:
active mode:TBD
idle mode:TBD
where
f
osc
is the oscillator frequency in MHz.
I
CC
values are given in mA and measured at
V
CC
= 5 V.
9) Typical power supply current (
I
CC typ
) with test conditiones as defined in note 4 and 5 is given by:
active mode, 12 MHz :45 mA
active mode, 16 MHz :72 mA
idle mode, 16 MHz :29 mA
10)Overload conditions occur if the standard operating conditions are exeeded, 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.
11)Not 100% tested, guaranteed by design characterization.
12)The typical
I
CC
values are periodically measured at
T
A
= +25 C but not 100% tested.
