November 3, 2008 FN6668.1 Complete overhaul of data sheet.
Revised with final specs and text. Changes include:
Added text and equations for Ibat for temp sense ON, and for relative accuracy for 1m vs 10m interval
Added text clarifying that no compensation at Vbat<2.7V
Revised entire Daylights savings time section
Added Application Example for DST
Added requirement for Vbat>1.8V in Vbat note.
Added applications circuit to survive Vbat<1.8V
Corrected all occurrences of Alpha tables
Corrected equations in NPPM section
Bolded and shaded the COMPENSATON registers in Table 1 to indicate READ ONLY and added note at top of table.
Added READ ONLY statements to IATR, ALPHA, BETA, XT0, ALPHAH
Fixed blank bits in register tables and in text.
Register table: Change default values for compensation to xx's, they are different with each device.
Added Datasheet curves
Add statement to applications section on crystal handling
Updated Pb-free note according to lead finish (Order Info)
Removed the "VDD" from the title on the first page
Global change for VBAT and VDD throughout document. Made the "BAT" and "DD" subscript.
Included Battery Reseal Function in Features and Description on page 1
Note 3 page 5, lower case "i" as in "inactive"
Included symbol "Temp" for temp sensor accuracy in DC table
First paragraph of DST Forward Registers had incorrect address stated (changed from 15h to 20h)
Corrected register 20h on page 22; added the DSTE bit to column 7
EQ2, page 19, corrected to "NPPM = IPPM+ALPHA(T-XT0)2/4096"
