The maximum read once time is given by
A.3.1.5
The programming time for a single phrase of four P-Flash words + associated eight ECC bits is dependant
on the bus frequency as a well as on the frequency f
following formulas.
The typical phrase programming time can be calculated using the following equation
The maximum phrase programming time can be calculated using the following equation
