DS1236A
20 of 20
NOTES:
1.
All voltages referenced to ground. A 0.1
μ
F capacitor is recommended between V
CC
and GND.
2.
Measured with V
CCO
,
CEO
, PF,
PF
,
ST
,
PBRST
, RST,
RST
, and
NMI
pin open. I
BAT
specified at
25
°
C.
3.
I
CCO1
is the maximum average load which the DS1236A can supply at V
CC
-0.3V through the V
CCO
pin
during normal 5-volt operation.
4.
I
CCO2
is the maximum average load which the DS1236A can supply through the V
CCO
pin during data
retention battery supply operation, with a maximum drop of 0.8 volts.
5.
With t
R
= 5
μ
s.
6.
V
CCO
is approximately V
BAT
-0.5V at 1
μ
A load.
7.
Sleep mode is not invoked.
8.
Sleep mode is invoked.
9.
t
REC
is the minimum time required before
CEI
/
CEO
memory access is allowed.
10.
t
CE
maximum must be met to ensure data integrity on power loss.
11.
IN input is less than V
TP
but V
CC
greater than V
CCTP
.
12.
All outputs except RST which is 25
μ
A maximum.
13.
All outputs except
RST
and
NMI
, which is 25
μ
A minimum.
14.
Pulse width of
NMI
requires that the IN pin remain below V
TP
. If the IN pin returns to a level above
V
TP
for a period longer than t
IPD
and before the t
NMI
period has elapsed, the
NMI
pin will immediately
return to a high.
15.
IN pin greater than V
TP
when V
CC
supply rises to V
BAT
. Example: IN tied to GND.
16.
IN pin less than V
TP
when V
CC
supply rises to V
BAT
.
17.
CEI
low.
18.
The WC/
SC
pin contains an internal latch which drives back on to the pin. This latch requires +200
μ
amps to switch states. The
ST
pin will sink
±
50
μ
amps in normal operation and
±
1
μ
amp in the
sleep mode.
19.
If no battery is attached (i.e., V
BAT
=GND) then V
OHL
will track V
CC
.
20.
ST
should be active low before the watchdog is disabled (i.e., before the
ST
input is tristated).
