See
Waveform of PSRAM 4-Word Page Read Operation” on page 25
Spec’s only applicable to parts 38F1030W0YxQF & 38F2030W0YxQF
At any given temperature and voltage condition, t
to device interconnection.
Timings of t
referenced to output voltage levels.
4-Word Page read only available for 16-Mbit PSRAM. No page mode feature for 8-Mbit PSRAM. Parts 38F1030W0YxQF &
38F2030W0YxQF do not support page mode, so this spec will not apply to them
CE# must go high and be maintained high for a minimum of 10ns at least once every 8,000ns
Applicable to 70ns initial access P-SRAM’s ( 38F1030W0YxQ2, 38F1030W0ZxQ0, 38F2030W0YxQ1, 38F2030W0YxQ2,
38F2030W0YxQF, 38F2030W0ZxQ2)
