ISD1800 Datasheet, PDF (2/26 Pages) Winbond – SINGLE-CHIP, SINGLE-MESSAGE VOICE RECORD/PLAYBACK DEVICE 6- TO 16-SECOND DURATION

I1800 SERIES
1. GENERAL DESCRIPTION
Winbond’s I1800 ChipCorder^® provides high-quality, single chip, single-message, record/playback
solution with user-selectable durations of 6 to 16 seconds. The CMOS devices include an on-chip
oscillator (with external control), microphone preamplifier, automatic gain control, anti-aliasing filter,
multilevel storage array, 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 in 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.
2. FEATURES
