I've been reading an app note found on line about this controller, but I can't find data sheets for the IC itself.
App note:

Can someone point me to the data sheet? Or answer this question: I see it used in a battery controller (indeed, the app note shows how). Does the ST6210 in such a charger application contain custom ROM code (provided by the product designer)? Or is this version of the controller already custom-tailored by SGS-Thomson to the charger application? The app note would have the reader believe that it's ready to plug in, add some supporting components, and power it on.
To support this, the app note goes into great detail about measuring voltage, and the means by which the controller determines the state-of-charge: by the slope of the voltage plot.
Any insight would be greatly appreciated.
Thanks,
