Single-Chip Voice Record/Playback Devices
8-, 10-, 12-, and 16-Minute Durations
ISD4004 Series
GENERAL DESCRIPTION
The ISD4004 ChipCorder
®
Products provide high-
quality, 3-volt, single-chip record/playback solu-
tions for 8- to 16-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™ feature, audio amplifier, and
high density, multilevel Flash storage array. The
ISD4004 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’s patented multilevel storage
technology. Voice and audio signals are stored
directly into memory in their natural form, providing
high-quality, solid-state voice reproduction.

ISD4004 Series
DETAILED DESCRIPTION
SPEECH/SOUND QUALITY
The ISD4004 ChipCorder series includes devices
offered at 4.0, 5.3, 6.4, and 8.0 KHz sampling fre-
quencies, allowing the user a choice of speech
quality options. Increasing the duration within a
product series decreases the sampling frequency
and bandwidth, which affects sound quality.
Please refer to the ISD4004 Series Product Summary
table on the second page to compare filter pass
band and product durations.
The speech samples are stored directly into on-chip
nonvolatile memory without the digitization and
compression associated with other solutions. Di-
rect analog storage provides a natural sounding
reproduction of voice, music, tones, and sound
effects not available with most solid-state solu-
tions.
PROGRAMMING
The ISD4004 series is also ideal for playback-only
applications, where single or multiple message
Playback is controlled through the SPI port. Once
the desired message configuration is created, du-
plicates can easily be generated via an ISD pro-
grammer.
PIN DESCRIPTIONS
VOLTAGE INPUTS (V
CCA
, V
CCD
)
To minimize noise, the analog and digital circuits
in the ISD4004 devices use separate power busses.
These +3 V busses are brought out to separate
pins and should be tied together as close to the
supply as possible. In addition, these supplies
should be decoupled as close to the package as
possible.
DURATION
To meet end system requirements, the ISD4004 se-
ries products are single-chip solutions at 8, 10, 12,
16 minutes.
GROUND INPUTS (V
SSA
, V
SSD
)
The ISD4004 series utilizes separate analog and
digital ground busses. The analog ground (V
SSA
)
pins should be tied together as close to the pack-
age as possible and connected through a low-
impedance path to power supply ground. The
digital ground (V
SSD
) pin should be connected
through a separate low-impedance path to pow-
er supply ground. These ground paths should be
large enough to ensure that the impedance be-
tween the V
SSA
pins and the V
SSD
pin is less than
3
W.
The backside of the die is connected to V
SS
through the substrate resistance. In a chip-on-
board design, the die attach area must be con-
nected to V
SS
or left floating.
FLASH STORAGE
One of the benefits of ISD’s ChipCorder technology
is the use of on-chip nonvolatile memory, which pro-
vides zero-power message storage. The message
is retained for up to 100 years (typically) without
power. In addition, the device can be re-record-
ed (typically) over 100,000 times.
MICROCONTROLLER INTERFACE
A four-wire (SCLK, MOSI, MISO, SS) SPI interface is
provided for ISD4004 control and addressing
functions. The ISD4004 is configured to operate as
a peripheral slave device, with a microcontroller-
based SPI bus interface. Read/Write access to all
the internal registers occurs through this SPI inter-
face. An interrupt signal (INT) and internal read-
only Status Register are provided for handshake
purposes.
