STi-C sensor ID

I purchased a new STi-C camera in February of 2013. I used it to do a color experiment during the 2017 eclipse. In analyzing the data, I see the ON-Semi data sheet shows substantial red response differences between the Gen-1 and Gen-2 versions of the KAI-0340 chip. My STi-C serial number is #5111111. Can you tell me which sensor is used in my camera?

Thanks,

Thanks for your quick reply. That chip has the better response curve for my project.
