Brief

ISD4000 Series

Single-Chip Voice Record/Playback Devices

2- to 16-Minute Durations

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.

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.
