1. Internal step-down products

The H8S/2148 B-masked product (HD64F2148B) includes an internal step-down circuit to
step down the microprocessor internal power supply voltage to the appropriate level.
One or two (in parallel) internal voltage regulating capacitors (0.47 µF) should be inserted
between the internal step-down pin (VCL pin) and VSS pin. The method of connecting the
external capacitor(s) is shown in figure 27.5.
For the 5-V and 4-V version products whose power supply (VCC) voltage exceeds 3.6 V, do
not connect the VCC power supply to the VCL pin of the internal step-down product. (Connect
the VCC power supply to the VCC1 pin, as usual.)
For the 3-V version product whose power supply (VCC) voltage is 3.6 V or less, connect the
system power supply to the VCL pin together with the VCC1 pins.
When switching from the F-ZTAT version product without the internal step-down function to
the F-ZTAT B-masked product with the internal step-down function, note that the VCL pin is
allocated to the same location as the VCC2 pin of the product without the internal step-down
function. Therefore, the difference in the circuits between before and after the switchover
should be considered when designing the PC board patterns.
