SERIAL NONVOLATILE WRITE CYCLE TIMING
Note:
(5) t
WC
is the time from a valid stop condition at the end of a write sequence to the end of the self-timed internal nonvolatile write cycle. It is
the minimum cycle time to be allowed for any nonvolatile write by the user, unless acknowledge polling is used.
