Notes: (5) tNVWC is the time from the falling edge of OE or CE (whichever occurs last) of the second read cycle in the
“start nonvolatile write cycle” sequence until the self-timed, internal nonvolatile write cycle is completed.
(6) Data is latched into the X84041 on the rising edge of CE or WE, whichever occurs first.
(7) Periodically sampled, but not 100% tested.
