Single-Chip Voice Record/Playback Devices: ISD4000 Datasheet

Datasheet:ISD4000.pdf

The ISD4000 ChipCorder® Products provide high-quality, 3-volt, single-chip record/playback solutions for 2- to 16-minute messaging applications which are ideal for cellular phones and other portable products. The CMOS based devices include an oscillator, antialiasing filter, smoothing filter, AutoMute® feature, audio amplifier, and high density, multilevel Flash storage array. The ISD4000 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 in on-chip nonvolatile memory cells, providing zero-power message storage. This unique, single-chip solution is made possible through ISD¡¯s patented multilevel storage technology. Voice and audio signals are stored directly into memory in their natural form, providing high-quality, solid-state voice reproduction.

ISD40000 SERIES CAN BE USED IN VARIOUS APPLICATIONS:
• Cellular phones
• Portable Digital Recorders (PDR)
• Automotive
• Telephone Answering Devices (TAD)
