DC and AC parameters
Table 34.
1. tCH + tCL must be greater than or equal to 1/ fC.
2. Typical values given for TA = 25 °C
3. Value guaranteed by characterization, not 100% tested in production.
4. Expressed as a slew-rate.
5. Only applicable as a constraint for a WRSR instruction when SRWD is set to '1'.
6. VPPH should be kept at a valid level until the program or erase operation has completed and its result (success or failure)
7. When using the page program (PP) instruction to program consecutive bytes, optimized timings are obtained with one
8. int(A) corresponds to the upper integer part of A. For example int(12/8) = 2, int(32/8) = 4 int(15.3) =16.
