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
