Single-Chip Voice Record/Playback Devices
2- to 16-Minute Durations
Recordings are stored in on-chip nonvolatile
memory cells, providing zero-power message stor-
age. This unique, single-chip solution is made
possible through ISD’s patented multilevel storage
technology. Voice and audio signals are stored
directly into memory in their natural form, provid-
ing high-quality, solid-state voice reproduction.

Products provide
high-quality, 3-volt, single-chip record/playback
solutions for 2- to 16-minute messaging applications
which are ideal for cellular phones and other
portable products. The CMOS based devices
include an oscillator, antialiasing filter, smoothing
filter, AutoMute
feature, audio amplifier,
and high density, multilevel Flash storage
array. The ISD4000 series is designed
to be used in a microprocessor- or
microcontroller-based system. Address and control
are accomplished through a Serial Peripheral
Interface (SPI) or Microwire serial interface to mini-
mize pin count.
