I studied your project o_cientista, but it only plays sound; does not record it.

Winbond make very good sound recording devices.  If you want simple play and record then stick with the basic devices that allow simple high and low logic to control play and record, however if you want to utilize cells structured in blocks so that you can use it like an answering machine then I have done this easily using Picbasic to write the control word to the ISD.  You will need to use Winbonds more advanced devices for this, and they have extra storage as a bonus.  Strongly recommend these devices - very reliable and very easy to use.  If you need help with any basic code to communicate with these then I can provide some on the forum.

Winbond have an application schematic as part of the data sheet on their website.  They show some examples of connecting a simple device as well as the 33000 and 4000 series chips.  Website is winbond.com

PIC18 is too small for it....that just suitable for 2/3 minute voice only!!
better to have SD card on it to get more voice
