[Coco] Panasonic IC Identification

[Andrew]

All:

I have a Panasonic card reader that has a couple of IC's (same #) that I 
am trying to identify/locate a datasheet for. I suspect that they are 
ADC's of some sort, but I am not completely certain.

The part # is MN6541 - I have checked panasonic semiconductor's site, 
but it didn't have any datasheet for the part (new or discontinued - and 
I paged through that for a long while to get to the MN#### parts - their 
search system is BROKEN).

The only reason I suspect an ADC is because of how the read head is 
hooked up, and the lines lead into a RJ45 plug - four of the lines are 
5VDC, GND, RED LED and GREEN LED - the other four are ???.

I suspect either one is "clock" and the others are a 3-bit ADC output - 
or maybe a couple are clock and a single line is 1-bit ADC output - dunno...

Thanks for any help you can provide - I just want to play with this 
surplus card reader...
