ISD2560SY Application Field and Working Principle

Interface - Voice Record and PlaybackISD2560SY is a voice record and playback integrated standard device with a built-in ADC/DAC, flash memory and controller. It supports length adjustable voice recording, non-volatile storage up to 30 seconds and multiple repeat playback.

Applications

ISD2560SY is widely used in diverse industries such as voice guidance, voice prompts for answering machines, voice messages for home automation, voice alarms for office automation, sound effects for toys, and interactive sound features for robots, etc. Besides, it can also be used in photoelectric toys, electronic education devices and electronic source material.

The Working Principles

ISD2560SY records audio and stores it in the onboard flash memory. The audio stored in the flash memory is then played back as needed. ISD2560SY is composed of two parts, memory and controller. The memory is where the audio is stored and the controller is responsible for controlling the recording and playback of the audio. When recording, the controller is used to initiate the ADC and the ADC itself converts the analog audio signal into digital data. The controller then uses this digital data to write the audio into the flash memory, thus providing non-volatile storage of the audio. Similarly, the controller can be used to initiate the DAC. The DAC uses the digital data stored in the memory to generate a corresponding analog audio signal. This signal can be used for playback of the audio. The controller is also used to control the length of the audio that can be recorded and stored. This can be adjusted from very short lengths, up to 30 seconds, depending on the desired use. Furthermore, the controller is also used to control the number of times the audio can be repeated for playback. This can be set to be once or multiple times, depending on the intended use. In summary, ISD2560SY integrated standard device is a very useful device with a variety of applications. It can be used to record and store audio, with an adjustable length and the ability to repeat the playback multiple times.
