I've tried posting this twice. I'm breaking it up into parts to see if
it posts.
My investigation of the CanoScan 8400F has so far found the following.
------------------------------------------------------
chips :
Scanner chip = GL843 [1]
I'm trying to get the datasheet on this. It's not
downloadable yet that I can see. I'll use the 842 datasheet for now.
I suspect the main differences between the 842 and 843 are increased
memory support and increased resolution support. The 8400F supports
3200x6400 scanning and any transparency up to 6x22cm.
Samsung K4S6411632H-UC75, 64Mb, 4Mb x 16 x 4 banks SDRAM = 8MB. [2]
Wolfson WM8199CDS image digitizer [3]
Allegro A3967SLB microstepping motor driver [4]
Allegro L6219DS Dual full-bridge PWM motor driver. [5]
A few other chips I didn't identify.
