Power Up Timing

Notes: 1.

Delays are measured from the time VCC is stable until the speciﬁed operation can be initiated.These parameters are periodically sampled

and not 100% tested.

Typical values are for TA = 25˚C and VCC = 5.0V

Nonvolatile Write Cycle Timing

Notes: 1.

tWC 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.
