Description
ISD4003 Series Single-Chip Voice Record/Playback Devices 4-, 5-, 6-, and 8-Minute Durations GENERAL DESCRIPTION The ISD4003 ChipCorder® Products provide highquality, 3-volt, single-chip Record/Playback solutions for 4- to 8-minute messaging applications which are ideal for cellular phones and other portable products. The CMOS-based devices include
More View an on-chip oscillator, antialiasing filter, smoothing filter, AutoMute™ feature, audio amplifier, and high density, multilevel Flash storage array. The ISD4003 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. Recordings are stored in on-chip nonvolatile memory cells, providing zero-power message storage. This unique, single-chip solution is made possible through ISD’s patented multilevel storage technology. Voice and audio signals are stored directly into memory in their natural form, providing high-quality, solid-state voice reproduction.
