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.

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

7025 FM T12

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.
