ISD4002-120SYI Product Details

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, AutoMute® 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.
