22.4.5 Usage Note
The specifications of the H8S/2128 F-ZTAT version and H8S/2124 Series mask ROM version
differ in terms of on-chip module functions provided and port (P47, P52) output specifications.
Also, while the F-ZTAT and mask ROM versions both satisfy the electrical characteristics shown
in this manual, actual electrical characteristic values, operating margins, noise margins, and other
properties may vary due to differences in manufacturing process, on-chip ROM, layout patterns,
etc.
When system evaluation testing is carried out using the H8S/2128 F-ZTAT version, the above
differences must be taken into consideration in system design, and the same evaluation testing
should also be conducted for the mask ROM version when changing over to that version.
