ISD1800 SERIES
1. GENERAL DESCRIPTION
Nuvoton’s ISD1800 ChipCorder® provides high-quality, single chip, single-message, record/playback
solution with user-selectable durations of 6 to 16 seconds. The CMOS devices include an on-chip
oscillator (with external control), microphone preamplifier, automatic gain control, anti-aliasing filter,
multilevel storage array, smoothing filter, and speaker amplifier. A minimum record/playback
subsystem can be configured with a microphone, a speaker, several passive components, two push
buttons, and a power source. Recordings are stored in on-chip nonvolatile memory cells, providing
zero-power message storage. This unique, single-chip solution is made possible through Nuvoton’s
patented multilevel storage technology. Voice and audio signals are stored directly into memory in their
natural form, providing high-quality, solid-state voice reproduction.

FUNCTION
VSSD, VSSA

REC 1

Ground Supplies: Similar to VCCA and VCCD, the
analog and digital circuits internal to the I1800
device use separate ground buses to minimize
noise. These pins should be tied together as close
as possible to the device.
I Record: The REC input is an active-HIGH record
signal. The device records whenever REC is
HIGH. This pin must remain HIGH for the duration
of the recording. REC takes precedence over
either playback (PLAYL or PLAYE) signal. If REC
is pulled HIGH during a playback cycle, the
playback immediately ceases and recording
begins. A record cycle is completed when REC is
pulled LOW. An End-of-Message (EOM) marker is
internally recorded, enabling a subsequent
playback cycle to terminate appropriately. The
device automatically powers down to standby
mode when REC goes LOW. This pin has an
internal pull-down device. Holding this pin HIGH
will increase standby current consumption.
PLAYE
3
I Playback, Edge-activated: When a HIGH-going
transition is detected on this input pin, a playback
cycle begins. Playback continues until an End-of-
Message (EOM) marker is encountered or the end
of the memory space is reached. Upon completion
of the playback cycle, the device automatically
powers down into standby mode. Taking PLAYE
LOW during a playback cycle will not terminate
the current cycle. This pin has an internal pull-
down device. Holding this pin HIGH will increase
standby current consumption.
PLAYL 4 I Playback, Level-activated: When this input pin
level transits from LOW to HIGH, a playback cycle
is initiated. Playback continues until PLAYL is
pulled LOW or an End-of-Message (EOM) marker
is detected, or the end of the memory space is
reached. The device automatically powers down
to standby mode upon completion of the playback
cycle. This pin has an internal pull-down device.
Holding this pin HIGH will increase standby
current consumption.
