(1) The F-ZTAT and mask ROM versions have been confirmed as fully meeting the reference
(2) On-chip power supply step-down circuit
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 following products incorporate an internal power supply step-down circuit, which
automatically drops down the internal power supply voltage to the optimum internal voltage
level: the F-ZTAT A-mask versions of the H8S/2148, H8S/2147, and H8S/2144
(HD64F2148A, HD64F2147A, and HD64F2144A) and the mask ROM versions of the
H8S/2148, H8S/2147, H8S/2144, and H8S/2143 (HD6432148S, HD6432148SW,
HD6432147S, HD6432147SW, HD6432144S, and HD6432143S).
The voltage-stabilization capacitor (0.47 F one or two connected in group) must be connected
between the VCL (internal power supply step-down) and VSS pins.
Figure 26.3 shows the connection of the external capacitors.

For the 3-V version whose power supply (V
VCL and VCC1 pins to the system power supply.
When changing from the F-ZTAT versions not incorporating an internal step-down circuit to
the F-ZTAT A-mask versions or mask ROM versions incorporating an internal step-down
circuit, the VCL pin has the same pin location as the VCC2 pin. Therefore, note that the circuit
patterns differ between these two types of products.
