ISD5008
Single-Chip Voice Record/Playback Device
4-, 5-, 6-, and 8-Minute Durations
Preliminary Datasheet
ISD5008 PRODUCT SUMMARY
The ISD5008 ChipCorder product is a fully-inte-
grated, single-chip solution which provides seam-
less integration of enhanced voice record and
playback features for digital cellular phones (GSM,
CDMA, TDMA, PDC, and PHS), automotive com-
munications, GPS/navigation systems, and porta-
ble communication products. This low-power, 3-
volt product enables customers to quickly and
easily integrate 4 to 8 minutes of voice storage
features such as one-way and two-way (full du-
plex) call record, voice memo record, and call
screening/answering machine functionality.
Like other ChipCorder products, the ISD5008 inte-
grates the sampling clock, anti-aliasing and
smoothing filters, and the multi-level storage array
on a single-chip. For enhanced voice features,
the ISD5008 eliminates external circuitry by also in-
tegrating automatic gain control (AGC), a power
amplifier/speaker driver, volume control, sum-
ming amplifiers, analog switches, and a car kit in-
terface. Input level adjustable amplifiers are also
included, providing a flexible interface for multiple
applications.
