• Manufacturer: Meet Spansion Inc.

AC CHARACTERISTICS
Note: Figure assumes 6 wait states for initial access and synchronous read. The Set Configuration Register command sequence
has been written with A18=0; device will output RDY with valid data.
1) RDY goes low during the two-cycle latency during a boundary crossing.
2) RDY stays high when a burst sequence crosses no boundaries.
Note: Figure assumes 6 wait states for initial access and synchronous read. The Set Configuration Register command sequence
has been written with A18=0; device will output RDY with valid data.
1) Burst suspend during the initial synchronous access
2) Burst suspend after one clock cycle following the initial synchronous access
