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. Cheers
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 of microcontroller. 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 (...)
hi laktronics is right .U r absolutely need to use a Uc or design your job with array of gates (need to know vhdl) for isd seri use isd25120 (25 series is suitable for your use)
Hi, I am trying to play audio clips in a isd 17240 chip and to control and give instructions i am using 8051 microcontroller (Philips P89v51rd2 being precise). But i am not able to even make the isd chip get into SPI mode!! Can any one help me with a basic piece of code for isd 17240? I am writing the (...)
Hi all Here is complete information about text to speech control or talking chip with two ready project based on PIC micro to demonstrated the interface with micro, I have also started a talking temperature controller with these chips isd 14XX are more power full chip to there other relevant chip and I (...)
i suggest you to use isd chip. they records and plays voice easyly.
Single-chip Voice Record / Playback IC isd * 20 to 240 second duration * Cascade for longer duration * Easy-to-use single chip * +5V voltage operation * Microprocessor controllable or manual switch * Fully addressable to handle multiple messages * On chip clock source and automatic (...)
Thanks un advance.
Hi all, I have a problem here. I'm using isd2548P as a speech IC to record the messages that i need to use for my project.I follow the PUSH BUTTON circuit that provided in the data sheet to record the messages.I try to record and play the speech but nothing can be heard when i play it. Undecided From the Winbond/isd chip corder FAQ (...)
Hi all, 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 (...)
i have a project about sound record. i use isd4003, my circuit is good. it can play and stop .But i don't understand why after 2 weeks sound recorded then every data in isd lost, it don't out sound. After, i record isd, it'll Okie.
Hi, 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 (...)
have a look at the isd4003 isd4003 In-stock Suppliers,isd4003 Price,PDF Datasheet Download - ,The isd4003 chipCorder? Products provide highquality, 3-volt, single-chip Record/Playback solutions for 4- to 8-min
hi guys, currently im trying to make a standalone sound recorder using isd 1760py chip. but after many attempts, i couldnt get a working result. datasheet =
Dear nirious Hi 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 .) Best Wishes
is there a easy to use chip that is similar to the winbond isd2560 . i need the new chip to be parallel addressable. as i already have code to control the isd chip. just need higher quality sound,,, maybe a parrallel controlable mp3 chip?
pls can someone tell me how get an isd 4004 chip on isis professional(proteus). i need it in my project design

works well, isd-300A1 from
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
Hi, I want to interface the isd 5116 chip coder from winbond with at89c52 (8052 from atmel) My problem is that at89c52 is 5v mc and isd5116 is a 3.3v so 1.I need a simple circuit to regulate my 5v power supply to 3~3.3v to power the isd5116 2.isd use i2c to comm with hosts (i.e mc) I want to know (...)
Dear All, I have read about keil compiler and their MON51. something i wanna ask are, 1. is MON51 and Keil able to debugging at souce-level like as C, or only at assembly level. 2. which one better, MON51 or isd51 Siswanto
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
Hi, 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
