AC CHARACTERISTICS
Notes:
1. Figure shows total number of wait states set to seven cycles. The total number of wait states can be programmed from two
cycles to seven cycles.
2. If any burst address occurs at a 64-word boundary, two additional clock cycle are inserted, and is indicated by RDY.
3. The device is in synchronous mode.
Figure 16.
CLK Synchronous Burst Mode Read (rising active CLK)
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, two additional clock cycle are inserted, and is indicated by RDY.
3. The device is in synchronous mode.
