I think they are gold.  It isn't really clear from the datasheet, or pkg
info on the website for the device.  It doesn't really look like the pkg
changes for RoHS, and yet they have a different PN for RoHS.  So I don't
know.  I have put a question to the manufacturer of the device, as well.

Hi Genny,

What is the plating on the CASON package?   I have not seen any problems
using a QFN (very similar package) with lead bearing solderpaste.

We have an IC we are using that is a "CASON" package.
Instead of leads, it just has pads on the bottom of the device. I think
it fits in a small outline layout.
The only other "leadless" device I am familiar with, really, is a BGA,
and those, the general consensus is that they shouldn't be switched to
RoHS without switching the solder paste, as well.
So my question is, are there any issues with switching a CASON pkg to
RoHS while still using SnPb solder paste?
