NOTES:
1.
WE
is high for a read cycle.
2.
OE
= V
IH
or V
IL
. If
OE
= V
IH
during write cycle, the output buffers remain in a high impedance state.
3.
t
WP
is specified as the logical AND of
CE
and
WE
. t
WP
is measured from the latter of
CE
or
WE
going low to the earlier of
CE
or
WE
going high.
4.
t
DH
, t
DS
are measured from the earlier of
CE
or
WE
going high.
5.
These parameters are sampled with a 50 pF load and are not 100% tested.
6.
If the
CE
low transition occurs simultaneously with or later than the
WE
low transition in Write
Cycle 1, the output buffers remain in a high impedance state during this period.
7.
If the
CE
high transition occurs prior to or simultaneously with the
WE
high transition, the output
buffers remain in a high impedance state during this period.
8.
If
WE
is low or the
WE
low transition occurs prior to or simultaneously with the
CE
low transition,
the output buffers remain in a high impedance state during this period.
9.
The expected t
DR
is defined as cumulative time in the absence of V
CC
with the clock oscillator
running.
10.
t
WR
is a function of the latter occurring edge of
WE
or
CE
.
11.
t
DH
and t
DS
are a function of the first occurring edge of
WE
or
CE
.
12.
RST (Pin1) has an internal pull–up resistor.
13.
Real–Time Clock Modules can be successfully processed through conventional wave–soldering
techniques as long as temperature exposure to the lithium energy source contained within does not
exceed +85°C. Post-solder cleaning with water washing techniques is acceptable, provided that
ultrasonic vibration is not used.
