use. The data retention current value of the SRAMs can then be added to the IBAT value of
the M41T315Y/V/W 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 the amount of data retention available (see
Table 17 on page
