ISD5008

SINGLE-CHIP, VOICE RECORD / PLAYBACK DEVICE 4-, 5-, 6- AND 8-SECOND DURATION

Unspecified 

ISD5008 Product

Duration/sample rate selection is accomplished

via software, allowing customers to optimize qual-

ity and duration for various features within the

same end product.

The ISD5008 device is designed for use in a micro-

processor- or microcontroller-based system. Ad-

dress, control, and duration selection are

accomplished through a Serial Peripheral Inter-

face (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 solid-state memory in their natural, un-

compressed form, providing superior quality voice

and music reproduction.

ISD5008 FEATURES

FULLY-INTEGRATED SOLUTION

• Single-chip voice record/playback solution

• Integrated sampling clock, anti-aliasing and

smoothing filters, and multi-level storage array

• Integrated analog features such as automatic

gain control (AGC), audio gating switches,

speaker driver (23mW with 8 ohm load),

summing amplifiers, volume control, and an

AUX IN/AUX OUT interface (e.g., for car kits).

LOW-POWER CONSUMPTION

• Single +3 volt supply

• Operating current:

ICC Play = 15 mA (typical)

ICC Rec = 25 mA (typical)

ICC Feedthru = 12 mA (typical)

• Standby current:

ISB = 1 µA

• Power consumption controlled by SPI or

Microwire control register

• Most stages can be individually powered

down for minimum power consumption

ENHANCED VOICE FEATURES

• One or two-way (full duplex) conversation

record (record signal summation)

• One- or two-way (full duplex) message

playback (while on a call)

• Voice memo record and playback

• Private call screening

• In-terminal answering machine

• Personalized outgoing message (given caller

ID information from host chip set)

• Private call announce while on call (given

CIDCW information from host chip set)

EASY-TO-USE AND CONTROL

• No compression algorithm development

required

• User-controllable sample rates of 8.0 kHz,

6.4 kHz, 5.3 kHz, or 4.0 kHz providing up to

8 minutes of voice storage.

• Microcontroller SPI or Microwire™ Serial

Interface

• Fully addressable to handle multiple

messages in 1200 rows

HIGH QUALITY SOLUTION

• High quality voice and music reproduction

• ISD’s standard 100-year message retention

(typical)

• 100,000 record cycles (typical)

OPTIONS

• Available in die form, PDIP, SOIC, TSOP, and

chip scale packaging (CSP)

• Compact µBGA chip scale package

available for portable applications

• Extended temperature (-20 to +70°C) and

industrial temperature (-40 to +85°C) versions

available
