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 Nuvoton’s patented multilevel storage technology. Voice and
audio signals are directly stored onto memory array in their natural form, providing high-quality voice
reproduction.
