The ISD1700 voice module is a simple and practical circuit board which will help you quickly familiarize yourself with ISD1700 chip. It is suitable for full range of ISD1700 chip and is featured with simple operation and complete functions. ISD1700 recording chip is a highly integrated chip of high performance. It can realize multi voice recording, the sampling rate can be regulated between 4K to 12K and the power supply range between 2.4V to 5.5V.
ISD1700 is also featured with new recording reminder function, when there is a new recording, LED will flash every few seconds to remind user that there is a new recording. In addition, there are 4 voice effects to inform users of the operation results, such as start recording, stop recording, erase, the next one and erase all and etc. The recording data is stored in the FLASH of the chip without any compression to ensure good voice and power-off storage. The chip is equipped with two independent input channels for voice signal, mic and analog signal. In the independent button mode, the chip will automatically switch to power down mode to save power after a certain functional operation is done. In SPI mode, the user can carry out more functional operation on the chip, such as playback any storage address and read/write analog Path Configuration register.
