26 / 46 page 32WQ and 64WQ Family with Asynchronous RAM Datasheet November 2007 26 Order Number: 251407-13 32WQ and 64WQ Family with Asynchronous RAM W5 tAW Address Setup to R-WE# (P-CS#) Going High 60 – 60 – ns W6 tCW P-CS# (R-WE#) Setup to R-WE# (P-CS#) Going High 60 – 60 – ns W7 tDH Data Hold from R-WE# (P-CS#) High 0– 0 – ns W8 tWR Write Recovery 0 – 0 – ns 5 W9 tBW R-UB#, R-LB# Setup to R-WE# (P-CS#) Going High 60 – 60 – ns tCEL P-CE# low-time restriction – 8,000 – – ns 7,8 W10 tWPH Write High Pulse Width 10 – – – ns 8 Notes: 1. See Figure 9, “AC Waveform PSRAM Write Operation” . 2. A write occurs during the overlap (tWP) of low P-CS# and low R-WE#. A write begins when P-CS# goes low and R-WE# goes low with asserting R-UB# or R-LB# for single byte operation or simultaneously asserting R-UB# and R-LB# for double byte operation. A write ends at the earliest transition when P-CS# goes high and R-WE# goes high. 3. tWP is measured from P-CS# going low to end of a write. 4. tAS is measured from the address valid to the beginning of a write. 5. tWR is measured from the end of a write to the address change. tWR applied in case a write ends as P-CS# or R-WE# going high. 6. W3 is 70 ns for continuous write operations over 50 times. 7. P-CE# must go high and be maintained high for a minimum of 10ns at least once every 8,000ns 8. Spec’s only applicable to parts 38F1030W0YxQF & 38F2030W0YxQF 9. Applicable to 38F2020W0ZTQ1, 38F2020W0ZBQ1, 38F2030W0YTQ1, 38F2030W0YBQ1, 38F2030W0ZTQ2, 38F2030W0ZBQ2, 38F1030W0ZTQ0, 38F1030W0ZBQ0.
