.
4. Value guaranteed by characterization, not 100% tested in production.
5. Expressed as a slew-rate.
6. Only applicable as a constraint for a WRSR instruction when SRWD is set to ‘1’.
7. V
PPH
should be kept at a valid level until the program or erase operation has completed and its result
(success or failure) is known.
8. When using the page program (PP) instruction to program consecutive bytes, optimized timings are
obtained with one sequence including all the bytes versus several sequences of only a few bytes (1
≤
n
≤
256).
9. int(A) corresponds to the upper integer part of A. For example int(12/8) = 2, int(32/8) = 4 int(15.3) =16.
