GENERAL DESCRIPTION

The ISD4003 ChipCorder? Products provide high-quality, 3-volt, single-chip Record/Playback solutions for 4- to 8-minute messaging applications which are ideal for cellular phones and other portable products. The CMOS-based devices include an on-chip oscillator, antialiasing filter, smoothing filter, AutoMute? feature, audio amplifier, and high density, multilevel Flash storage array. The ISD4003 series is designed to be used in a microprocessor- or microcontroller-based system. Address and control are accomplished through a Serial Peripheral Interface (SPI) or Microwire Serial Interface to minimize pin count.
