If the SRAM includes a second chip enable pin
(E2), this pin should be tied to V
OUT
.
If data retention lifetime is a critical parameter for
the system,it is important to review the data reten-
tion
current
specifications
SRAMs being evaluated. Most SRAMs specify a
data retention current at 3.0V. Manufacturers gen-
erally specify a typical condition for room temper-
ature along with a worst case condition (generally
at elevated temperatures). The system level re-
quirements will determine the choice of which val-
ue to use.
for
the
particular
Thedata retentioncurrent value of theSRAMs can
then be added tothe I
BAT
value of the M48T212Y/
V to determine the total current requirements for
data retention. The available battery capacity for
the SNAPHAT of your choice can then be divided
by this current to determine theamount of data re-
tention available (see Table 15).

lations, please see Application Note AN1012.
