ISD1400 SERIES
1. GENERAL DESCRIPTION
Winbond’s ISD1400 ChipCorder
®
series provide high-quality, single-chip, Record/Playback solutions
to short-duration messaging applications. The CMOS devices include an on-chip oscillator,
microphone preamplifier, automatic gain control, anti-aliasing filter, smoothing filter, and speaker
amplifier. A minimum Record/Playback subsystem can be configured with a microphone, a speaker,
several passive components, two push buttons and a power source. Recordings are stored into on-
chip non-volatile memory cells, providing zero-power message storage. This unique, single-chip
solution is made possible through Winbond’s patented Multi-Level Storage (MLS) technology. Voice
and audio signals are stored directly into memory in their natural form, providing high-quality, solid-
state voice reproduction.
