1.1
The ISD5008 ChipCorder product can be config-
ured via software to operate at 4.0, 5.3, 6.4, and
8.0 kHz sampling frequencies, allowing the user a
choice of speech quality options. Increasing the
duration decreases the sampling frequency and
bandwidth, which affects sound quality. Table 1
compares 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.
1.2
To meet end system requirements, the ISD5008
device is a single-chip solution which provides
from 4 to 8 minutes of voice record and playback,
depending on the sample rates defined by cus-
tomer software.

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 over 100,000 times (typically).
1.4
A four-wire (SCLK, MOSI, MISO, SS) SPI interface is
provided for ISD5008 control, addressing func-
tions, and sample rate selection. The ISD5008 is
configured to operate as a peripheral slave de-
vice with a microcontroller-based SPI bus inter-
face. Read/Write access to all the internal registers
occurs through this SPI interface. An interrupt sig-
nal (INT) and internal read-only Status Register are
provided for handshake purposes.
1.5
The ISD5008 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 or
third-party programmers. For more information on
available application tools and programmers
