    Information Storage Devices ISD2500 Chip Corder® Series provides high-quality, single-chip Record/Playback solutions for 32- to 120-second messaging applications. The CMOS devices include an on-chip oscillator, microphone preamplifier, automatic gain control, antialiasing filter, smoothing filter, speaker amplifier, and high density multi-level storage array. In addition, the ISD2500 is microcontroller compatible, 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 ISDs patented multilevel storage technology. Voice and audio signals are stored directly into memory in their natural form, providing high quality, solid-state voice reproduction.
