ISD4003 Series
Single-Chip Voice Record/Playback Devices
4-, 5-, 6-, and 8-Minute Durations
GENERAL DESCRIPTION
The ISD4003 ChipCorder
廬
Products provide high-
quality, 3-volt, single-chip Record/Playback solu-
tions for 4- to 8-minute messaging applications
which are ideal for cellular phones and other por-
table products. The CMOS-based devices include
an on-chip oscillator, antialiasing filter, smoothing
filter, AutoMute鈩?feature, audio amplifier, and
high density, multilevel Flash storage array. The
ISD4003 series is designed to be used in a micro-
processor- or microcontroller-based system. Ad-
dress and control are accomplished through a
Serial Peripheral Interface (SPI) or Microwire Serial
Interface to minimize pin count.
Recordings are stored in on-chip nonvolatile
memory cells, providing zero-power message
storage. This unique, single-chip solution is made
possible through ISD鈥檚 patented multilevel storage
technology. Voice and audio signals are stored
directly into memory in their natural form, providing
high-quality, solid-state voice reproduction.
