GENERAL DESCRIPTION
Winbond’s ISD2500 ChipCorder® Series provide high-quality, single-chip,Record/Playback solutions for 32- to 64-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 into on-chip nonvolatile memory cells, providing zero-power message storage.
