Notes: (5) Typical values are for TA = 25°C and nominal supply voltage.
(6) tWC is the minimum cycle time to be allowed from the system perspective unless polling techniques are used. It is the maximum
time the device requires to automatically complete the internal write operation.
(7) tWPH and tDW are periodically sampled and not 100% tested.
