27.5 Usage Note
Although both the F-ZTAT and mask ROM versions fully meet the electrical specifications listed
in this manual, due to differences in the fabrication process, the on-chip ROM, and the layout
patterns, there will be differences in the actual values of the electrical characteristics, the operating
margins, the noise margins, and other aspects.
Therefore, if a system is evaluated using the F-ZTAT version, a similar evaluation should also be
performed using the mask ROM version.
