VOICE RECORDER AND PLAYBACK MODULE

Voice recorder and playback module is a made for the purpose of recording those messages and playback which required frequently at some places like platform, train, instruction, mobile, etc. When I started to work on this project I was not able to find some easy instruction to made one for me. So I decided to put it on my blogs so that other can made this one easily.

Now a my voice recorder module is based on IC ISD17XX/1720 which is DIP package and 2.4-5 volt operating voltage. It is a multi-message voice record. It can be operated standalone or by microcontroller(SPI) mode. Recording are stored into on-chip flash memory, providing zero power message storage.

In the spi mode , the user has full control via serial interface to operate the device Now here is the pin diagram of the ISD1700
