ISD5008 Datasheet, PDF (2/47 Pages) List of Unclassifed Manufacturers – SINGLE CHIP VOICE RECORD PLAYBACK DEVICE 4-, 5-, 6-, AND 8- MINUTE DURATIONS

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:
I_{CC Play} = 15 mA (typical)
I_{CC Rec} = 25 mA (typical)
I_{CC Feedthru} = 12 mA (typical)
• Standby current:
I_SB = 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.
