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.

ISD40000 SERIES CAN BE USED IN VARIOUS APPLICATIONS:
• Cellular phones
• Portable Digital Recorders (PDR)
• Automotive
• Telephone Answering Devices (TAD)
The ISD4000 ChipCorder®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.
