ADVANCED INFORMATION ISD18C00 SERIES
1. GENERAL DESCRIPTION
Nuvoton’s ISD18C00 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 ( uses shared speaker as microphone),
automatic gain control, anti-aliasing filter, multilevel storage array, smoothing filter, and speaker
amplifier. A minimum record/playback subsystem can be configured with 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
1, 16
Ground Supplies: Similar to VCCA and VCCD, the
analog and digital circuits internal to the I18C00
device use separate ground buses to minimize
noise. These pins should be tied together as
close as possible to the device.
REC 1 2 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.
