Usage Note

The F-ZTAT and mask ROM versions both satisfy the electrical characteristics shown in this
manual, but actual electrical characteristic values, operating margins, noise margins, and other
properties may vary due to differences in manufacturing process, on-chip ROM, layout patterns,
and so on.
When system evaluation testing is carried out using the F-ZTAT version, the same evaluation
testing should also be conducted for the mask ROM version when changing over to that version.
