Summary
Fixed package drawing dimensions.
Operating table. Changed V
Changed to Pre-Production status. Added text to Trickle Charger section.
Improved spec limits on V
limits in DC Operating table. Added companion register table with default
values. Added Package Marking Scheme and board footprint. Devices marked
with Date Codes 0440 and higher comply with the revision of the datasheet.
Changed description of POR flag and manual reset (pg. 5, 10). Added notes to
Absolute Maximum Ratings.
Rewrote section on battery backup. Added comment about unused CNT pins.
Removed -S packaging option which is Not Recommended for New Designs.
Added ESD and MSL ratings which are valid for Date Codes 0440 and higher.
Not recommended for new designs. As an alternative, use FM3127xB for 5V
designs or FM31L27xB for 3V designs.
Changed to Production status. These products are no longer Not
Recommended for New Designs (NRND). Updated ESD ratings. Updated lead
temperature rating in Abs Max table. Removed battery insertion sequence text
(p. 6). The sequence is no longer necessary for devices with date codes after
0701.
