GENERAL DESCRIPTION
Information Storage Devices’ ISD1000A Chip-
Corder
Series provides high-quality, single-chip
record/playback solutions for 16- and 20-second
messaging applications. The CMOS devices
include an on-chip oscillator, microphone pream-
plifier, automatic gain control, antialiasing filter,
smoothing filter, and speaker amplifier. In addi-
tion, the ISD1000A Series is fully microprocessor-
compatible, allowing complex messaging and
addressing to be achieved.
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 reproduc-
tion.
DETAILED DESCRIPTION
The ISD1000A ChipCorder Series devices are
designed to Record and Play back audio and
voice information in a single chip with a minimum
of circuit complexity. This compact, easy-to-use,
nonvolatile, low-power solution has been made
possible by ISD's multilevel storage technology —
a breakthrough in storage technology in EEPROM.
ISD’s multilevel storage technology results in stor-
age density that is eight times greater than digital
memory. The ISD1000A nonvolatile analog array
consists of 128K cells — the equivalent of 1 Mbits
of digital storage.
The ISD1000A Series eliminates the need for dig-
ital conversion, digital compression, and voice
synthesis techniques which often compromise
voice quality and are more complicated to use.
The ISD1000A Series includes signal conditioning
circuits and control functions which enable a com-
plete, high-quality Recording and Playback sys-
tem in a single device. The ISD1000A is available
in two versions, which store voice in 16- or 20-sec-
ond arrays. Additional devices may be cascaded
