MMA8652 vs MMA8451

Hi,

 

I am just in the process of selecting a new Accelerator.  I have rounded my selection down to two chips, the MMA8652 and the MMA8451.  Am I correct in thinking other than one is 12bit and the other 14bit, and they have different packages, they are both similar in complexity?  My meaning is, one is not easier to program and configure over the other chip.

 

Also from a design point of view on low power battery powered products, is it better to have the INT pins pull-up or pull-down?

 

Lastly looking at the datasheet on the MMA8652, the circuit diagram shows polarized capacitors around the chip, I think these should be none polarized.  Am I correct?

 

Thanks,
