Table 13. AC Characteristics (33MHz operation)

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

3. 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)

4. Details of how to find the date of marking are given in Application Note, AN1995.

Test conditions specified in Table 8. and Table 9.
