Flash memory characteristics
VDDQ = 2.7 - 3.6V, VDD = 1.65 - 2V, TA = -40 / 85 °C unless otherwise specified.
Note:
Flash read access for sequential addresses is 0 wait states at 96 MHz.
Flash read access for non-sequential accesses requires 2 wait states when FMI clock is
above 66 MHz. See STR91xF Flash Programming Manual for more information.
