  • Where to buy

The ISD4002 ChipCorder series provides high-quality, 3-volt, single-chip record/playback solutions for 2- to 4-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 Auto Mute feature audio amplifier and high density multilevel Flash memory 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. Recordings are stored into the on-chip Flash memory cells Providing zero-power message storage. This unique single-chip solution utilizes Nuvoton's patented multilevel storage technology. Voice and audio signals are directly stored onto memory array in their natural form providing high-quality voice reproduction.

Features:

  • Single 3 volt supply
  • Low-power consumption
  • Standby current:  ICC_Standby = 1 μA (typical)
  • Single-chip durations of 120, 150, 180, and 240 seconds
  • High-quality, natural voice/audio reproduction
  • AutoMute feature provides background noise attenuation
  • No algorithm development required
  • Micorcontroller SPI or Microwire™ Serial Interface
  • Fully addressable to handle multiple messages
  • Non-volatile message storage
  • 100K record cycles (typical)
  • 100-year message retention (typical)
  • On-chip clock source
  • Power consumption controlled by SPI
  • Available in die, PDIP, SOIC and TSOP
  • Packaged type: Lead-Free
