1. GENERAL DESCRIPTION
Winbond’s ISD2500 ChipCorder
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.
