Single-Chip Voice Record/Playback Device

16-Minute Duration

Preliminary Data Sheet

GENERAL DESCRIPTION

The ISD MicroTAD-16M ChipCorder¨ Product pro-

vides high-quality, 3-volt, single-chip record/

playback solutions for 16-minute messaging ap-

plications which are ideal for telephone answer-

ing devices (TADs). The CMOS-based devices

include an on-chip oscillator, antialiasing filter,

smoothing filter, AutoMute™ feature, audio am-

plifier, and high density, multilevel Flash storage

array. The ISD MicroTAD-16M is designed to be

used in a microprocessor- or microcontroller-

based system. Address and control are accom-

plished 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 stor-

age technology. Voice and audio signals are

stored directly into memory in their natural form,

providing high-quality, solid-state voice repro-

duction.
