ISD5008 General Description

The ISD5008 ChipCorder® product is a fully integrated, single-chip, 3V solution providing seamless integration of four to eight minutes of enhanced messaging features. Additional analog functions and audio gating have also been integrated into the ISD5008 to allow easy interface with integrated digital cellular chipsets. Audio paths have been designed to enable full duplex conversation record, voice memo, answering machine (including outgoing message playback) and call screening features. This product enables playback of messages while the phone is in standby, and both simplex and duplex playback of messages while on a phone call.

The ISD5008 integrates the sampling clock, antialiasing and smoothing filters, and the multi-level storage array onto a single-chip. This low power product eliminates external system components by integrating automatic gain control, power amplifier/ speaker driver, volume control, summing amplifiers, analog switches and an auxiliary output interface.

Adjustable input amplifiers provide a flexible interface for multiple applications. Sample rates are dynamically programmable for optimizing the audio quality and the durations for the various features required.

The ISD5008 device is designed for use in a microprocessor- or microcontroller-based system. Address, control and duration are enabled through a Serial Peripheral Interface (SPI) or Microwire™ serial interface to minimize pin count. Recordings are stored in ISD's patented multilevel memory cells making zero-power message storage possible. Voice and audio are stored directly into solid-state memory in their natural, uncompressed from, creating superior quality voice and music reproduction.
