Notes: 1. Delays are measured from the time VCC is stable until the speciï¬ed operation can be initiated. These parameters are periodically sampled
and not 100% tested.
2. Typical values are for TA = 25ËC and VCC = 5.0V

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.
