DESCRIPTION
Initial release
Replaced Pin Configuration
In the Electrical Characteristics table, changed V TL(MIN) from 0.5V to 0.46V and
V TL(MAX) from 4.1V to 4.4V; changed V HY(MIN) from 0.22V to 0.21V
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 PROG (programming time) EC
table parameter from 12.5ms to 10ms for version A2 (see also pages 1, 13).
Removed t FPD and updated t PDH , t MSP , t W0L accordingly. Changed I PROG max to

Electrical Characteristics table, changed V TH , V TL based on V PUP and data retention
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 IL(MAX) spec from 0.3V to 0.5V;

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
