sound chip schematic

Anyone know how to connect the sound chip to 8051 microcontroller chip?

My sound chip model is ISD2590.

Anyone having the connection circuit or program regarding this?

Anyone can help?? Urgent!!
 

Hi ru,

You can connect this chip as in the attached file, by changing the mc68hc705 microcontroller with the 8051 microcontroller

But all the matter depends on what functions you want the 8051 to do?

If you want more help, Please specify the functions that you want so I can draw more usable schmatic for you

sorry to trouble you.. but do u know how to program it to record some sound and playback when a sensor detected some thing?
this circuit i already connected, but just cannot do the recording and playback..
can give me some guidelines? thanks..
 

Hi There,

For this chip there are many operation Modes, and as I feel your problem is in selecting the right Mode

To solve this problem easily try the following two steps: -

1- Operate this chip in The Push button Mode only (without the microcontroller)
See the circuit Pushbutton.jpg

Please do no go to the next step if the circuit does not run

Note the sequence should be
pd pin should=0 after that P/R pin =0 (recording) then CE=0 for short while (you should use a push button key because the pd pin and the P/R pin are latched at the failing edge of CE
** That means nothing will happen if you change pd or P/R pin without the failing edge of the CE PIN)


2- now lets to use the microcontroller to record and playback
The circuit and some notes are in the ALL.jpg

See the recording and playing waveforms

Also see the compressed program (playandrec program.exe), note I did not test it with the circuit

I hope that is useful for you
