NOTES:
CE0#, CEX# and OE# are switched low after Power-Up.
1. The tYLPH/tYHPH and tPHEL3/tPHEL5 times must be strictly followed to guarantee all other read and program specifications.
2. The power supply may start to switch concurrently with RP# going low.
3. The address access time and RP# high to data valid time are shown for the DD28F032SA-80 and 5.0V VCC operation.
Refer to the AC Characteristics-Read Only Operations for 3.3V VCC operation and all other speed options.
