Winbond's ISD1420 provides 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 nonvolatile memory cells, providing zero-power message storage. Voice and audio signals are stored directly into memory in their natural form, providing high-quality, solid-state voice reproduction.
