Write Cycle Timing
Power Up Timing
1.
Delays are measured from the time V
CC
is stable until the specified operation can be initiated. These parameters are peri-
odically sampled and not 100% tested.
Nonvolatile Write Cycle Timing
1.
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.
