DS1238A
13 of 13
NOTES:
1.
All voltages referenced to ground.
2.
Measured with V
CCO
,
CEO
, PF,
ST
, RST,
RST
, and
NMI
pin open.
3.
I
CCO1
is the maximum average load which the DS1238A can supply at V
CC
-.3V through the V
CCO
pin
during normal 5-volt operation.
4.
I
CCO2
is the maximum average load which the DS1238A can supply through the V
CCO
pin during data
retention battery supply operation, with a maximum drop of 0.8 volts for commercial, 1.0V for
industrial.
5.
With t
R
= 5
μ
s.
6.
V
CCO
is approximately V
BAT
-0.5V at 1
μ
A load.
7.
t
REC
is the minimum time required before
CEI
/
CEO
memory access is allowed.
8.
t
CE
maximum must be met to insure data integrity on power loss.
9.
All outputs except RST which is 25
μ
A max.
10.
All outputs except
RST
,
RTV
, and
NMI
which is 25
μ
A min.
11.
The
ST
pin will sink
±
50
μ
A in normal operation. The OSCIN pin will sink
±
5
μ
A in normal
operation. The OSCSEL pin will sink
±
10
μ
A in normal operation.
12.
I
BAT
is measured with V
BAT
=3.0V.
13.
ST
should be active low before the watchdog is disabled (i.e., before the
ST
input is tristated).
