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 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
CC
specification when the address lines are stabilizing.
3) 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.
4) Not 100% tested, guaranteed by design characterization.
5) Only valid for C505A and C505CA.
6) Only valid for C505A and C505CA in programming mode.
7)
I
CC
(active mode) is measured with:
XTAL1 driven with
t
R
,
t
F
= 5 ns, 50% duty cycle ,
V
IL
=
V
SS
+ 0.5 V,
V
IH
=
V
CC
– 0.5 V; XTAL2 = N.C.;
EA = Port 0 = RESET =
V
CC
; all other pins are disconnected.
8)
I
CC
(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
CC
– 0.5 V; XTAL2 = N.C.;
RESET = EA =
V
SS
; Port0 =
V
CC
; all other pins are disconnected;
9)
I
CC
(active mode with slow-down mode) is measured : TBD
10)
I
CC
(idle mode with slow-down mode) is measured : TBD
11)
I
PD
(power-down mode) is measured under following conditions:
EA = Port 0 =
V
CC
; RESET =
V
SS
; XTAL2 = N.C.; XTAL1 =
V
SS
;
V
AGND
=
V
SS
;
V
AREF
=
V
CC
;
all other pins are disconnected.
12) The typical
I
CC
values are periodically measured at
T
A
= + 25
°
C but not 100% tested.
13) The maximum
I
CC
values are measured under worst case conditions (
T
A
= 0
°
C or – 40
°
C and
V
CC
= 5.5 V)
