If time is not absoulely critical, you can use the internal RC. Set it
to 32KHz regularly and boost it to 2MHz (for 19200 baud) for data dump.
You also need to switch off the RS232 drivers (eg. Max232), since it
draws 10mA all the time. You can log the start and end real time to
recalibate your data stream.

I would advise against using any Maxim part. In this case, you may be
much better off making your own RS-232 driver. An RS-232 signal needs to
rest at -3V or more. Instead of making your own minus voltage, I suggest
you use the RS-232 signal from the PC used to read out the data as a
supply.
