AC Characteristics
Notes:
1. PA = Program Address, PD = Program Data, VA = Valid Address for reading status bits.
2. “In progress” and “complete” refer to status of program operation.
3. A20–A12 are don’t care during command sequence unlock cycles.
4. Addresses are latched on the first of either the rising edge of AVD# or the active edge of CLK.
5. Either CS# or AVD# is required to go from low to high in between programming command sequences.
6. The Synchronous programming operation is independent of the Set Device Read Mode bit in the Burst Mode
Configuration Register.
7. AVD# must toggle during command sequence unlock cycles.
8. t
AH
= 45 ns.
9. CLK must not have an active edge while WE# is at V
IL
.
