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 voice information 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 single device. The ISD1000A is available in two versions, which store voice in 16- or 20-second arrays.

VCCD P/R XCLK EOM PD CE NC ANA OUT ANA IN AGC MIC REF MIC VCCA SP– DIP/SOIC On-chip control functions make the ISD1000A Series very easy to use in a wide array of applications. Each device offers a variety of operating modes and interface options. The devices may be used in applications that require little more than a few switches and a battery. The devices may also be integrated into electronic systems where digital addresses can be provided for more sophisticated message addressing and control. The ISD1000A array is organized into 160 segments. Addresses A0 through A7 provide access to each segment in the array for message addressing. Addressing provides the capability of constructing messages by combining stored phrases and sounds. to achieve longer recording durations. The nonvolatile storage array is based on productionproven, low-power CMOS EEPROM technology. The highly integrated ISD1000A Series contains all the basic functions required for high-quality voice Recording and Playback. The noise-cancelling Microphone Preamplifier and Automatic Gain Control (AGC) record both low-volume and highvolume sounds. The AGC attack and release times are adjusted by an external resistor and capacitor. Antialiasing is performed by a continuous fifth-order Chebyshev filter, requiring no external components or clocks to give toll-quality reproduction. The low corner of the passband.
