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.
