Working Principle of ISD1620BSYR

The ISD1620BSYR works by converting the voice signal into digital data. This data is then stored in an on-chip Flash Memory chip. The data is also compressed to reduce required storage space. The Flash memory can store up to 32 minutes of record at a monaural 4 kHz sample rate. The device can then be used to playback the recorded data. It supports both analog and digital input/output. The device has a power detection circuit that can detect changes in the power supply voltage and switch off the device. This feature makes it more efficient and reduces the risk of data loss. The device also supports software commands that can be used to control the device. In order to control the device, an external microcontroller is needed.
