GENERAL DESCRIPTION
Information Storage Devices' ISD2500 Chip-
Corder
Series provides high-quality, single-chip
Record/Playback solutions for 32- to 120-second
messaging applications. The CMOS devices
include an on-chip oscillator, microphone pream-
plifier, automatic gain control, antialiasing filter,
smoothing filter, speaker amplifier, and high den-
sity multi-level storage array. In addition, the
ISD2500 is microcontroller compatible, allowing
complex messaging and addressing to be
achieved.
Recordings are stored in on-chip nonvolatile mem-
ory cells, providing zero-power message storage.
This unique, single-chip solution is made possible
through ISD's patented multilevel storage technol-
ogy. Voice and audio signals are stored directly
into memory in their natural form, providing high-
quality, solid-state voice reproduction.
DETAILED DESCRIPTION
Speech/Sound Quality
The ISD2500 Series includes devices offered at
4.0, 5.3, 6.4, and 8.0 KHz sampling frequencies,
allowing the user a choice of speech quality
options. Increasing the duration within a product
series decreases the sampling frequency and
bandwidth, which affects sound quality. Please
refer to the ISD2500 Series Summary table on
page 1-79 to compare filter pass band and product
durations.
The speech samples are stored directly into on-
chip nonvolatile memory without the digitization
and compression associated with other solutions.
Direct analog storage provides a very true, natural
sounding reproduction of voice, music, tones, and
sound effects not available with most solid-state
digital solutions.
Duration
To meet end system requirements, the ISD2500
Series offers single-chip solutions at
64
*, 60, 75, 90, and 120 seconds. Parts may also
be cascaded together for longer durations.
