 No, Gerhard, I haven't.

 The best I can find so far (and "best" includes "can actually purchase in
 20K volume") is the Phillips PCF8570.

Hi ANDY!
Since I am looking for somthing similar,  I found the Dallas DS2404.  It has
twice the ram as the Philips part and has a real time clock as well.  It will
work with the 1 wire protocol or a 3 wire protocol or both.  It also has a 48
bit unique serial number rom.
They are $3.89 in 1000 piece qty.
