The H8S/2258 Group, H8S/2238B, and H8S/2236B incorporates an internal power supply step-
down circuit. Use of this circuit enables the internal power supply to be fixed at a constant level of
approximately 3.0 V, independently of the voltage of the power supply connected to the external
V
above can be held down to virtually the same low level as when used at approximately 3.0 V. If
the external power supply is 3.0 V or below, the internal voltage will be practically the same as the
external voltage.
The H8S/2239 Group, H8S/2238R, H8S/2236R, H8S/2237 Group, and H8S/2227 Group do not
have an on-chip internal power supply voltage step-down circuit.
An external power supply should be connected to the V
