Information
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 “address + 1”, “address + 2”, or “address + 3”, additional clock delay cycles are inserted, and are indicated
by RDY.
3. The device is in synchronous mode with wrap around.
4. D8–DF in data waveform indicate the order of data within a given 8-word address range, from lowest to highest. Starting address in figure
is the 4th address in range (0-F).

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 “address + 1”, “address + 2”, or “address + 3”, additional clock delay cycles are inserted, and are indicated
by RDY.
3. The device is in asynchronous mode with out wrap around.
4. DC–D13 in data waveform indicate the order of data within a given 8-word address range, from lowest to highest. Starting address in figure
is the 1st address in range (c-13).
