NOTES:
1. Write pulse width (tWP) is defined from CE# or WE# going low (whichever goes low last) to CE# or WE# going high (whichever
goes high first). Hence, tWP = tWLWH = tELEH = tWLEH = tELWH. Similarly, write pulse width high (tWPH) is defined from CE# or
WE# going high (whichever goes high first) to CE# or WE# going low (whichever goes low last). Hence,
tWPH = tWHWL = tEHEL = tWHEL = tEHWL.
2. Refer to Table 7, “Command Bus Operations” on page 24 for valid AIN or DIN.
3. Sampled, but not 100% tested.
4. See Figure 11, “AC Input/Output Reference Waveform” on page 49 for timing measurements and maximum allowable input
slew rate.
5. See Figure 9, “Write Operations Waveform” on page 47.
6. VCCMax = 3.3 V for 32-Mbit 0.25 Micron product.
