Nuvoton Technology Corp. America Voice Record and Playback ISD4003-08ME

The ISD4003-08ME is a single-chip voice record and playback device designed for applications requiring up to 8 minutes of audio messaging. It operates on a 3-volt supply and features low power consumption, with typical operating currents of 15 mA during playback and 25 mA during recording, and a standby current of just 1 ¬µA. The device utilizes a CMOS architecture that includes an on-chip oscillator, anti-aliasing and smoothing filters, an audio amplifier, and a high-density multilevel Flash memory array for non-volatile message storage. This product supports high-quality audio reproduction and incorporates an AutoMute feature to reduce background noise. It is fully addressable and can handle multiple messages without the need for algorithm development, making it suitable for integration into microprocessor or microcontroller-based systems via SPI or Microwire Serial Interface. The ISD4003-08ME is available in various package forms, including die, PDIP, SOIC, and TSOP, and operates within a temperature range of 0¬8C to +70¬8C for commercial units, with extended and industrial options available. The device is rated for 100,000 record cycles and offers a message retention period of up to 100 years.
