Interface - Voice Record and Playback

ISD1612BPIY is a complete series of single chip voice record and playback systems with built-in flash memory. It is a low-cost and small-size IC that is easy to use, extend and customize. It can be used in variety of applications such as toys, home appliances, home automation, games and so on.

The basic components of ISD1612BPIY Series include a controller, a voltage regulator, a flash memory, a microphone amplifier and the necessary additional components. ISD1612BPIY can record and playback analog and digital (pulse code) voice signals. It can store up to 2 minutes of sound and support multiple levels of output including serial port data, digital pulse code and analog signals.

The ISD1612BPIY Series has an integrated controller with clock, command interpreter and internal address decoder. The built-in flash memory stores up to 100 stories or messages, recorded or loaded from the Microcontroller Interface. This eliminates the need for an external memory, reducing overall system size and cost.

The microphone amplifier amplifies the weak signals generated by the sound to levels that can be sensed by the ISD1612BPIY controller. The additional necessary components include resistors, capacitors, and other components required for the proper operation of the system.

The main working principle of the ISD1612BPIY Series is that it converts the analog sound signals into digital signals, stores them in the flash memory, and plays them back in various formats, either through analog signals or in the form of pulse code. The controller automatically chooses the right content based on the command sent by the user. The unit can be re-programmed, if needed, using the pre-programmed commands. The user can also record messages for playback using the microphone amplifier and the system will save them in the flash memory.

The ISD1612BPIY Series offers quality performance, with low power consumption and high reliability. Additionally, it is available in a variety of packages, making it versatile to use in different types of applications.
