Features

Information Storage Devices ISD-VM1110A Chip-On-Board module provides
high-quality, single-chip record/playback solutions to short duration
messaging applications.  The ISD-VM1110A module integrates the ISD1110
ChipCorder die, which contains an on-chip oscillator, microphone
preamplifier,  automatic gain control,  antialiasing filter,  smoothing
filter and a speaker amplifier along with passive components on a single
PC board.  The ISD-VM1110A enables a minimum record/playback subsystem to
be configured easily with a microphone,  a speaker, two push-buttons, and
a power source. All connections are provided via a multi-pin edge
connector or through-holes for a 100-mil header or wire connects.

Recordings are stored in nonvolatile memory cells,  providing zero-power
message storage.  This unique solution is made possible through ISD's
patented Multi-Level Storage Technology, whereby voice and audio signals
are stored directly, in their natural analog form, into EEPROM memory.
Direct analog storage allows natural voice reproduction in a single-chip
solid-state solution.  Storage allows natural voice reproduction in a
single-chip solid-state solution. voice/audio reproduction
