Note:
  1. Cycling over full temperature range.

Maximum operating frequencies are shown in the following table, but are limited by the Embedded Flash access time when the processor is fetching code out of it. These tables provide the device maximum operating frequency defined by the field FWS of the EEFC_FMR register. This field defines the number of wait states required to access the Embedded Flash Memory.
