values for electrical characteristics shown in this manual. However, actual performance
figures, operating margins, noise margins, and other properties may vary due to differences in
the manufacturing process, on-chip ROM, layout patterns, etc.
When system evaluation testing is carried out using the F-ZTAT version, the same evaluation
tests should also be conducted for the mask ROM version when changing over to that version.
The H8S/2148 F-ZTAT does not incorporate an internal power supply step-down circuit.
When changing over to F-ZTAT versions or mask ROM versions incorporating an internal
step-down circuit, the VCC2 pin has the same pin location as the VCL pin in a step-down
circuit.
Therefore, note that the circuit patterns differ between these two types of products.
