20.3.7
The H8S/2319C F-ZTAT has an on-chip voltage step down circuit that automatically lowers the
power supply voltage, inside the microcomputer, to an adequate level. A capacitor (0.1 µF) should
be connected between the internal voltage step down circuit pin (V

20.4
Although both the F-ZTAT and mask ROM versions fully meet the electrical specifications listed
in this manual, there may be differences in the actual values of the electrical characteristics,
operating margins, noise margins, and so forth, due to differences in the fabrication process, the
on-chip ROM, and the layout patterns.
If the F-ZTAT version is used to carry out system evaluation and testing, therefore, when
switching to the mask ROM version the same evaluation and testing procedures should also be
conducted on this version.
