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. Clock is set for active rising 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. This waveform represents a synchronous burst mode, the device will also operate in reduced wait-state

handshaking under a CLK synchronous burst mode.
