I have given some toughts to this already...

--> either SC16IS750. Has 3.3V operation, but you'll need I2C levelconverter (e.g. PCA9517) and 1.8V regulator. Easier to interface to the 232 transceiver.



--> or SC16IS850L. Has 1.8V operation, no need for I2C level converter, but needs 1.8V regulator. and some tricks to interface to 232 transceiver.
