GENERAL DESCRIPTION
The ISD5008 ChipCorder product is a 3V fully-integrated, single-chip solution which provides
seamless integration of enhanced voice record and playback features for digital cellular phones (GSM,
CDMA, TDMA, PDC, and PHS), automotive communications, GPS/navigation systems, and portable
communication products. This low-power, 3-volt device enables customers to quickly and easily
integrate 4 to 8 minutes of voice storage features such as one-way or two-way (full duplex) call record,
voice memo record, and call screening/answering machine functionality.
Like other ChipCorder products, the ISD5008 integrates the sampling clock, anti-aliasing and
smoothing filters, and the Multi-Level Storage (MLS) array into a single chip. For enhanced voice
features, the ISD5008 eliminates external circuitry mostly by also integrating automatic gain control
(AGC), a power amplifier/speaker driver, volume control, summing amplifiers, analog switches, and a
car kit interface. Input level adjustable amplifiers are also implemented, providing a flexible interface
for multiple applications.
Duration/sample rate selection is accomplished via software, allowing customers to optimize quality
and duration for various features within the same end product.
The ISD5008 device is designed for use in a microprocessor- or microcontroller-based system.
Address, control, and duration selection are accomplished through a Serial Peripheral Interface (SPI)
or Microwire Serial Interface to minimize pin count.
Recordings are stored into on-chip non-volatile memory cells, providing zero-power message storage.
This unique, single-chip solution is made possible through Nuvoton’s patented MLS technology. Voice
and audio signals are stored directly into solid-state memory in their natural, uncompressed form,
providing superior quality voice and music reproduction.
