ISD4002 SERIES

1. GENERAL DESCRIPTION

The ISD4002 ChipCorder® series provides high-quality, 3-volt, single-chip record/playback solutions

for 2- to 4-minute messaging applications ideally for cellular phones and other portable products. The

CMOS-based devices include an on-chip oscillator, anti-aliasing filter, smoothing filter, AutoMute®

feature, audio amplifier, and high density multilevel Flash memory array. The ISD4002 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 minimize pin

count.

Recordings are stored into the on-chip Flash memory cells, providing zero-power message storage.

This unique single-chip solution utilizes Winbond’s patented multilevel storage technology. Voice and

audio signals are directly stored onto memory array in their natural form, providing high-quality voice

reproduction.
