1. 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. This unique, single-chip solution is

made possible through Winbond’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.
