ISD4004 - Single-Chip Voice Record/Playback

Download the ISD4004 datasheet PDF. This datasheet also covers the ISD variant, as both devices belong to the same single-chip voice record/playback family and are provided as variant models within a single manufacturer datasheet.

General Description

The ISD4004 ChipCorder® Products provide highquality, 3-volt, single-chip record/playback solutions for 8- to 16-minute messaging applications which are ideal for cellular phones and other portable products.

Key Features

  • Single-chip voice record/playback solution Single +3 volt supply Low-power consumption.
  • Operating current: ICC Play = 15 mA (typical) ICC Rec = 25 mA (typical).
  • Standby current: 1 µA (typical).
  • Single-chip durations of 8, 10, 12, and 16 minutes High-quality, natural voice/audio reproduction AutoMute feature provides background noise attenuation during periods of silence No algorithm development requi.

Single-Chip Voice Record/Playback Devices 8-, 10-, 12-, and 16-Minute Durations ISD4004 Series GENERAL DESCRIPTION The ISD4004 ChipCorder® Products provide highquality, 3-volt, single-chip record/playback solutions for 8- to 16-minute messaging applications which are ideal for cellular phones and other portable products. The CMOS-based devices include an on-chip oscillator, antialiasing filter, smoothing filter, AutoMute™ feature, audio amplifier, and high density, multilevel Flash storage array. The ISD4004 series is designed to be used in a microprocessor- or microcontroller-based system. Address and control are accomplished through a Serial Peripheral Interface (SPI) or Microwire Serial Interface to minimize pin count.
