NOTES:

CE0#, CE1# 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 5V VCC operation of the 28F016SA-080. Refer to

the AC Characteristics Read Only Operations for 3.3V VCC and all other speed options.
