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
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.
Addresses
Note: Figure assumes 7 wait states for initial access and automatic detect synchronous read. D0–D7 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 7th address in
range (A6). See “Requirements for Synchronous (Burst) Read Operation”. The Set Configuration Register command sequence
has been written with A18=1; device will output RDY with valid data.
