Notes: 1. Typical values are for T
A
= 25°C and V
CC
= 5.0V
Notes: 1. Cb = total capacitance of one bus line in pF.
Notes: 1. Over recommended operating conditions, unless otherwise specified
Notes: 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.
Notes: 1. This parameter is not 100% tested.
