Preliminary data.

Details of how to find the Technology Process in the marking are given in AN1995, see also Section 13: Part numbering.

tCH + tCL must be greater than or equal to 1/ fC

Value guaranteed by characterization, not 100% tested in production.

Only applicable as a constraint for a WRSR instruction when SRWD is set at 1.

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).

int(A) corresponds to the upper integer part of A. E.g. int(12/8) = 2, int(32/8) = 4 int(15.3) =16.
