ISD4002 Series
Single-Chip Voice Record/Playback Devices
120-, 150-, 180-, and 240-Second Durations
GENERAL DESCRIPTION
The ISD4002 ChipCorder® products provide highquality, 3-volt, single-chip record/playback solutions for 2- to 4-minute messaging applications ideal for cellular phones and other portable products. The CMOS-based devices include an onchip oscillator, anti-aliasing filter, smoothing filter, AutoMute™ feature, audio amplifier, and high density, multilevel Flash storage array. The ISD4002 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.
