I1800 SERIES

1. GENERAL DESCRIPTION

Winbond’s I1800 ChipCorder

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.
