Yes.
I only have the pd69200 version but the three versions are theoretically
compatible and microchip advise obviously to use the last one.
I describe the three names in case of future specific things even if I hope
there won't be and to have a clear version of which version is supported. Do you
prefer to use pd692x0 compatible instead?
