My MC output is pulse dial which is connected to dial relay
I want to put a DTMF transmitter which take the pulse input and convert into tone.

please help me
thank you

You could do it all with just an atmel microcontroler. You don't really need the other chips. You will have a hard time finding a single site which stocks all those items because some are obsolete . Good luck.

It would also help if you let people know your location ........

i am from singapore and if possible i want to buy ic form internet. aslo i will be using 89c51 mc where all those function are not available as well as its easy for me to do programing on it.

thanks
