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
Deleted “contact factory” note in Ordering Information; updated Pin Description and
Pin Configurations to reflect changes in pin assignment of UCSPR package
Corrected part number in Ordering Information table
Deleted the automotive version reference in the Features section
Added the automotive version reference to the Features section
