GENERAL DESCRIPTION
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 solid-state memo
