Find control algorithm

Hi all,
FM95HS02EM8XEM is a rolling code generation from Fairchild, that now
is going out of production. I need its control algorithm to implement
it into another microcontroller
Can anyone help me ?

thanks in advance

do you have a link to the datasheet ?? just curious -- would like to see
what the chip does to evaluate what it would take to reverse engineer and
re-implement.

you can find it at:
http://eshop.engineering.uiowa.edu/NI/pdfs/01/23/DS012302.pdf.
Fairchild purchased it from National some years ago.

do you want to maintain compatibility with existing recievers ?? or would
replacing both be an option ??

doing an equivalent function would be dirt simple -- matching exactly what
they do would be highly difficult without them coughing up the exact
algorithm -- The documentation states that the details of the encoder are
available to customers -- time to make a phone call !!

if you need 100% compatibility -- I'd be calling fairchild or buying up
every single last one of the darn things I could find :)

or place an order for your 10 year projected needs now before it goes out of
production :)

(starting to sound like it'll be easier to just find another chipset that
will do the job, unless fairchild will cough up the alogithm !!)

I need the 100% compatibility with existing receivers. I have some
problems to receive this algorithm from Fairchild, because
intellectual property, so i'm trusting in someone helping me to find
it anywhere. An idea about any Internet site, where I can try to find
it ?

thank you

No clue -- at this point -- I would be figuring out how many I need for
repair and replacement for the next 5-10 years and place an order before
they go our of production -- then find a new chip for future designs

OK! Thanks for your replies
