Interface and connectivity ICs

1) What is the difference between ST232A and ST202? The pin out and all data seems to be identical, but ST202 seems to be slightly cheaper. 2) Is it possible to use only the switch capacitor inverter, but not the voltage doubler?

I want to utilize the very low power supply current of typical 1.5 mA to make a galvanic separated RS-232 interface, which is driven by RTS and DTR (trough two diodes) on the RS-232 side. The plan is to connect the cathodes of the two diodes to V+ an...
