ISD1760EYI

Introduction

ISD1760EYI is a single-chip voice recorder and playback device designed as embedded system-on-a-chip solution with integrated memory, analog and digital circuit. It can record up to 530 seconds of digital audio and playback in continuous mode, looping mode and interrupt mode, even in extreme audio environments. In addition to voice recording, it can also store digital data, such as sound effects and sound patterns. The chip integrates the micro-controller, non-volatile memory, audio analogue front end, record/playback logic, address decoder and associated peripheral circuitry into a single device.

Application Field

The ISD1760EYI chip is ideal for a wide range of applications, including mobile phones, communication systems, MP3 players, security systems, toys, educational systems and other voice recording applications. With its low cost and low power consumption, the ISD1760EYI has become a popular choice for embedded voice recording and playback applications.

Working Principle

The ISD1760EYI records digital audio information into its integrated non-volatile memory. When the audio information is recorded, an address decoder translates the data into digital format and stores the information in the integrated non-volatile memory. The playback is achieved by reading the digital audio information from the memory and converting it into an analogue audio signal. The address decoder reads the audio information from the memory and sends it through the on-chip analogue filter to the audio output port. The filter helps eliminate background noise and ensures perfect sound quality.

Conclusion

In conclusion, the ISD1760EYI is an integrated voice recording and playback device that is suitable for a wide range of applications. It can store up to 530 seconds of digital audio and playback it continuously, looping or interrupted. The integrated micro-controller, non-volatile memory, analogue and digital circuitry, address decoder and associated circuits make it an ideal choice for embedded voice recording and playback applications.
