ISD4003 Series ChipCorder

The ISD4003 ChipCorder series provides high-quality, 3-volt, single-chip record/playback solutions for 4- to 8-minute messaging applications ideally for cellular phones and other portable products. The CMOS-based devices include an on-chip Oscillator anti-aliasing Filter smoothing Filter AutoMute feature, Audio Amplifier and high density multilevel Flash memory 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. Recordings are stored into the on-chip Flash memory cells, providing zero-power message storage. This unique single-chip solution utilizes Winbonds patented multilevel storage technology. Voice and Audio signals are directly stored onto memory array in their natural form, providing high-quality voice reproduction. By Winbond Electronics Corp America
