ISD1800 Series ChipCorder |
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. |
