Initial release.
Replaced Pin Configuration.
In the Electrical Characteristics table, changed V
V
In the Copy Scratchpad [55h] section, corrected the copy time from 13ms to 12.5ms.
Added the SFN package and updated the Ordering Information table.
In the Pin Configuration, added a note to the CSP package outline “*See package
reliability report for important guidelines on qualified usage conditions.”
In the Electrical Characteristics table, changed the t
table parameter from 12.5ms to 10ms for version A2 (see also pages 1, 13).
Removed t
0.8mA to match GBD.
Updated Memory Function Example table.
Added CSP package outline drawing number to Pin Configuration.
Changed V
In the Absolute Maximum Ratings, changed storage temp to -55°C to +125°C; in the
Electrical Characteristics table, changed V
to 40 years min at 85°C; added note to retention spec: “EEPROM writes can become
nonfunctional after the data-retention time is exceeded. Long-term storage at
elevated temperatures is not recommended; the device can lose its write capability
after 10 years at +125°C or 40 years at +85°C.”
In the Ordering Information table, removed all leaded part numbers and added the
TDFN-EP package.
In the Electrical Characteristics table, changed the V
removed from the t
Notes 17 and 18; corrected Note 20.
Added EP function to the Pin Description table.
Added to Figure 11 Write-Zero Time Slot.
In the Pin Configuration, added the package drawing information/weblink and a note
that the SFN package is qualified for electro-mechanical contact applications only,
not for soldering. Added the SFN Package Orientation on Tape-and-Reel section. In
the Ordering Information, added note to contact factory for availability of the UCSPR
package. Added note that TO-92 T&R leads are formed to approximately 100-mil
spacing.
In the SFN Pin Configuration, added reference to Application Note 4132.
Added Package Information table.
Created newer template-style data sheet.
