Hello,

I am working on some vintage circuits and need the datasheet for the Mostek MK6007 40-pin IC. I can't find anything anywhere on the internet other than it "might be similar to the Mostek MK5007", but that IC only has 28 pins. Anyone that might have this, it would be greatly appreciated!
I was reading through some posts and the member MrChips mentioned this chip in a post about a frequency counter, but just that it was and obsolete part, which I am aware, as the IC date code is 7321, so yeah, 1973!

That thread is here:
https://forum.allaboutcircuits.com/threads/frequency-counter-ic.194681/

Again, Any help would be much appreciated!

 

Here is the best I can find -block diagram and pinout:

Hello,

Have a look at this databook:

Thanks Bertus and Keith, I appreciate your responses, I'll keep digging, hopefully I can at least find the pin-out, seems this chip is an anomaly, not much anywhere about it....

 

You are wasting your time trying to find an archaic existing solution that you could have spent implementing the modern solution I suggested in the previous thread.

Presumably, this is because of lack of familiarity. If you would go with a modern microcontroller, you would learn a valuable skill for the future.

 

Pretty much any 8-bit device with a counter/timer peripheral will be able to handle this task. It is not overly difficult.

 

I appreciate the advice, but I am not using this for a modern circuit, nor am I unfamiliar with other micro-controllers, obviously if I wanted to design something new, I would not use this IC. I am a collector of vintage IC's and electronics, and want to preserve as much as I can. I was just asking if anyone has the datasheet and pin-out so that I can document it, and also build something that uses it.
thanks

 

Hello,

The link for the databook came from bitsavers.
There is a load of old books and datasheets sorted by manufacturer over there:

Thanks Bertus, I've scoured those and still cannot find the MK6007. This is going to be my white whale... If you know anyone that has vintage stuff, please let me know. I appreciate the help...
