GENERAL DESCRIPTION
Information Storage Devices’ ISD1000A ChipCorder® Series provides high-quality, single-chip record/playback solutions for 16- and 20-second messaging applications.
The CMOS devices include an on-chip oscillator, microphone preamplifier, automatic gain control, antialiasing filter, smoothing filter, and speaker amplifier.
In addition, the ISD1000A Series is fully microprocessorcompatible, allowing complex messaging and addressing to be achieved.
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.
