Write Cycle Timing
Power-up Timing
Notes: (1) Delays are measured from the time V
CC
is stable until the specified operation can be initiated. These parameters are not 100% tested.
V
CC
slew rate should be between 0.2mV/μsec and 50mV/μsec.
(2) Typical values are for T
A
= 25°C and V
CC
= 5.0V
Nonvolatile Write Cycle Timing
Note:
(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.
