1. See Important note on page 6.
2. Details of how to find the technology process in the marking are given in AN1995, see also Section 13: Ordering
information.
3. tCH + tCL must be greater than or equal to 1/ fC.
4. Value guaranteed by characterization, not 100% tested in production.
5. Only applicable as a constraint for a WRSR instruction when SRWD is set to ‘1’.
6. When using PP and PW instructions to update consecutive bytes, optimized timings are obtained with one sequence
including all the bytes versus several sequences of only a few bytes (1 ≤n ≤256).
7. int(A) corresponds to the upper integer part of A. E.g. int(12/8) = 2, int(32/8) = 4 int(15.3) =16.
