Actually the part number is CSB238 for the board alone and
CDK238 for the board mounted in an enclosure with a 1/4VGA
passive color LCD and touch screen.

BTW, the CS89712 is an EP7312 die and a CS8900a die
mounted in the same package.  If you look at the specs you will
see that the CS89712 uses Chip Select 2 (nCS2) and external 
interrupt 3 (EINT3) to talk to the CS8900a die.
