Description:
1.The ISD1700 voice module is a simple and practical board designed to quickly familiarize       you with the ISD1700 series of chips. It is suitable for the full range of ISD1700 chips, with simple operation and complete functions.

2.The ISD1700 series of recording and playback chips is a highly integrated, high performance chip. It can record in multiple stages, the sampling rate can be adjusted from 4K to 12K, and the power supply range can be between 2.4V and 5.5V. The ISD1700 also has a new recording reminder function.

3.When there is a new recording, the LED flashes once every few seconds to prompt the user to have a new recording.

4.There are also 4 sound effects to remind the user of the results of the operation, such as start recording, stop recording, erasing, next song and all erasure. The recorded data is stored in the FLASH of the chip, without any compression, so it has better sound quality and power-off storage.

5.The chip has two independent voice signal input channels, microphone input and analog signal input. In the independent button mode, when a function is completed, the chip will automatically enter the power-down mode to reduce power consumption. In SPI mode, the user can perform more functions on the chip.

6.For recording and playback of any storage address, read and write the Analog Path Configuration Register (APC)
