Program the PIC in the sequence you need to recall and connect the respective output pins PIC to the switching pins of the isd chip to reacll a particulr message.
Most of the application cicruits will be found on the chip datasheet.

I have been told that isd devices have a crappy quality
I have two engineering sample of the isd5116 and would
like to realize a prototype controlled with IIC with any kind
do you have any ideas further more to store 4 minutes of
good audible quality audio signal?
someone tell me instead of using an isd (...)

Is there anyone who have an experience on writing a source code to play a message of isd 2548 chip? Actually i tried to write a source code in C and using a PIC to play the message.The mode i use is the addressing mode.I didn't use the operational mode because I'm using the addressing mode to record the message into the speech IC.When i

If this is for a one-off project, consider using one of the old isd voice chips, such as
the isd1420 'chipcorder'. That gives you twenty seconds of addressable speech, and
has a very simple parallel interface. It can even be used as a stand-alone device without
using a microcontroller. They are almost always available (...)

The good method is to write a computer program that uses a simple handshake protocol with a microcontroller through serial port. You can connect sound card output to analog input of isd chip. Microcontroller is also attached to isd1700 chip through SPI. In that case, the computer program plays .wav file, sends RECORD to the (...)

isd part os ok. You didnt mention anything about the ATmega 8535 seen in your schematic. ry running your circuit without the interface to the micro. Usually no deletion of data takes place unless any comand is given or the Microcontroller does it or finally the isd chip is damaged. Cheers

I have designed a circuit that plays voices using a PIC and a isd4003. It plays and records well but sometimes the voice in isd would get deleted. After I record it back, it becomes OK again. Does anyone has any idea how to delete voices in the isd voice chip? I have read the datasheet of the isd but (...)

It is very simple! We will have a ic ( like a isd series ) that consist some latch . in first step we will have a A/D converter . when the voice changed to the digital value , you can save them with latches as well as . when you need them , you can get them and give them to the D/A converter . (by pushing the key .)

Did you consider using a dedicated solution ? (for example the isd-300LP from Cypress). It will give you the full transfer speed, which is very important. For example, I'm very dissapointed after trying to implement a SmartMedia card writer on USB using the FT245BM device from FTDI, because I can't get enough speed, even though the protocol is work

think that you need 5 minutes record (and play) time
and your sample frequency is 8khz...
it means in one second you are saving 8bit*8000 data with 8bit adc without any compression algorithm..
for 5 minutes it makes 5*60*8000=2.4 megabyte... its too large...
perhaps you can decrease that using lower sample frequency but than qualyty of voice wi

can i use external memory for storing the sound?????????? though 8051
The speed of 8051 is not enough to handle sound. You might need a dsp like chip.
It is easier to do it with isd or APR chips. Both comes in all flavor to cater your need.

a simple but very useful device for radio fans.
Repeater base on isd2560/75 or 90 chip. Lower record time means that sound quality is better, so the best choice would be 2560. System is controlled by PIC. To input signal goes from radio , is recording and playing, signals shorter ther

Have never seen that chip before and only do assembler but a few things you might like to check into.
The isd4002 says it uses SPI but I think its a custom format that cannot be reproduced by the 2520s Spi module - you may have to use your own custom software to send and receive the data - I have a sensor that similarly states its spi b
