Recordings are stored in on-chip non-volatile
memory cells, providing zero-power message stor-
age. This unique, single-chip solution is made possi-
ble through ISD’s patented multilevel storage
technology. Voice and audio signals are stored
directly into memory in their natural form, provid-
ing high quality, solid state voice reproduction.
high quality, low power, single-chip record/playback
solutions for 16-minute messaging applications such
as Telephone Answering Devices (TAD), Personal
Digital Assistants (PDA) and Personal Digital
Recorders (PDR) and PBX applications. The
CMOS-based devices include an on-chip
oscillator, anti-aliasing filter, smoothing
filter, AutoMute

feature, audio amplifier
and high-density multilevel Flash storage array
that requires battery power to record and playback
messages. The MicroTAD product 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.
ISD MicroTAD CAN BE USED IN VARIOUS APPLICATIONS:
• Telephone Answering Devices (TAD)
• Personal Digital Assistants (PDA)
• Portable Digital Recorders (PDR)
• PBX/voicemail
