ISD4003-04MSYI is an IC interface—Voice Record and Playback, which is designed and integrated by ISD Corporation. ISD Corporation is providing world-leading industrial solutions and products to all types of human-machine interface applications by creating possible ultra-long duration digital audio storage solutions, content-rich multi-media solutions, enhanced voice prompt and voice recognition solutions. This IC has become the new partner and choice of the global market in recent years.

The application field of ISD4003-04MSYI IC mainly includes consumer electronics, automotive electronics and communication device, educational electronics and home security system, etc. It is widely used in consumer electronic products such as toys, electronic books, greeting cards; automotive electronic products such as car keys, car alarms and so on. In these industries, the integrated chip functions as a voice recorder, voice playback and speech recognition embellisher. It can also be used as a remind tool on the communication device, tracking and supervision tool of home security system, operational auxiliary tool in educational electronics and so on.

As an IC interface, the design and working principle of ISD4003-04MSYI is quite complex. It is based on the integration of four types of integrated circuits – SRAM, PROM, FLASH and EEPROM. SRAM is widely used in embedded memories as its fast access speed, low cost and low voltage operation allows fast and flexible working. PROM is mainly used to store program code; FLASH is used to store program parameters, while EEPROM is used to store user data. These four types of integrated circuits enable ISD4003-04MSYI to play audio files with a duration ranging from one second to 128 minutes, be triggered by external signals, control inputs, automatic restart and an on-chip voice recognition system.

In addition, it can store dozens of sections of voice messages and its built-in multiple automatic restart features enable it to support centralized system control. Its self-trigger feature provides the advantage of way shorter activation time which is significant for small electronic devices.

Because of this, ISD4003-04MSYI can provide longer audio duration than traditional IC, it’s low power consumption and cost effective than other flash recorders. The integrated chip can be operated from 1.8V to 5V voltage supply, which makes it suitable for the application on portable electronic devices. Besides, it has excellent power management features such as programmable sleep mode, auto-diagnostic mode and low power consumption voice playback, which can guarantee long battery life and work efficiency.

All in all, ISD4003-04MSYI is a novel IC interface which provides consumers with an excellent choice for recording and playback of audio files. With its longer recording duration and low power consumption, this integrated chip proves to be a cost-effective solution to the wider range of digital voice applications.
