AC Characteristics
Notes:
1. Figure shows total number of wait states set to four cycles. The total number of wait states can be programmed from
two cycles to seven cycles. Clock is set for active falling edge.
2. If any burst address occurs at a 64-word boundary, one additional clock cycle is inserted, and is indicated by RDY.
3. The device is in synchronous mode.
4. In the Burst Mode Configuration Register, A17 = 0.
