GENERAL DESCRIPTION
Information Storage Devices’ ISD1000A ChipCorder® Series provides high-quality, single-chip record/playbacksolutions 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.

DETAILED DESCRIPTION
The ISD1000A ChipCorder Series devices are designed to Record and Play back audio and voiceinformation in a single chip with a minimum of circuit complexity. This compact, easy-to-use, nonvolatile, low-power solution has been made possible by ISD's multilevel storage technology — a breakthrough in storage technology in EEPROM. ISD’s multilevel storage technology results in storage density that is eight times greater than digital memory. The ISD1000A nonvolatile analog array consists of 128K cells— the equivalent of 1 Mbits of digital storage. The ISD1000A Series eliminates the need for digital conversion, digital compression, and voice synthesis techniques which often compromise voice quality and are more complicated to use. The ISD1000A Series includes signal conditioning circuits and control functions which enable a complete, high-quality Recording and Playback system in a singledevice. The ISD1000A is available in two versions, which store voice in 16- or 20-second arrays. Additional devices may be cascaded
