ISD1600B SERIES
1. GENERAL DESCRIPTION
The Nuvoton® ISD1600B ChipCorder® Series is a high quality, fully integrated, single-chip singlemessage voice record and playback device ideally suited to a variety of electronic systems. The
message duration is user selectable in ranges from 6.6 seconds to 40 seconds, depending on the
specific device. The sampling frequency of each device can also be adjusted from 4 kHz to 12 kHz
with an external resistor, giving the user greater flexibility in duration versus recording quality for each
application. Operating voltage spans a range from 2.4 V to 5.5 V to ensure that the ISD1600B devices
are optimized for a wide range of battery or line-powered applications.
The devices include an on-chip oscillator (with external resistor control), microphone preamplifier with
Automatic Gain Control (AGC), anti-aliasing filter, Multi-Level Storage (MLS) array, smoothing filter,
Pulse Width Modulation (PWM) Class D speaker driver, and current output. Voice signals can be fed
into the chip through a differential microphone input for recording. The PWM output can directly drive
a standard 8 Ω speaker or a typical buzzer, while the separate single-ended current output can drive
an external amplifier.
Recordings are stored into the on-chip Flash memory cells, providing zero-power message storage.
This unique single-chip solution is made possible through Nuvoton’s patented Multi-Level Storage
(MLS) technology. Audio data are stored directly in solid-state memory without digital compression,
providing superior quality voice and music reproduction.

PIN NAME
SOIC / PDIP
FUNCTIONS
PIN NO.
VSSD
1
Digital Ground: VSSD is the ground for digital circuits. It is
important to have a separate path for each ground back to
the system ground terminal to minimize noise.
REC
2
Record: The device starts recording whenever REC
transits from High to Low and stays at Low. Recording stops
when the signal returns to High. This pin has an internal
pull-up resistor [1] and an internal debounce on falling edge.
PLAYE
3
Edge-trigger Playback: A playback operation starts when
this input detects a low going signal exceeding the specified
debounced time. This pin has an internal pull-up resistor [1]
and an internal debounce on both falling & rising edge.
PLAYL
4
Level-trigger Playback: A playback operation begins when
this input detects a low going signal and remains at Low.
Playback stops when the signal returns to High. This pin has
an internal pull-up resistor [1] and an internal debounce on
falling edge.
VSSA
5
Analog Ground: VSSA is the ground for analog circuits. It is
important to have a separate path for each ground back to
the system ground terminal to minimize noise.
MIC+
6
Microphone Positive Input: The input transfers the signal
to the preamplifier. The internal Automatic Gain Control
(AGC) circuit controls the gain of the preamplifier. An
external microphone should be AC coupled to this pin via a
series capacitor. The capacitor value, together with an
internal 10 KΩ resistance on this pin, determines the lowfrequency cutoff for the ISD1600B passband.
MIC-
7
Microphone Negative Input: This is the inverting input to
the microphone preamplifier. It provides input noisecancellation, or common-mode rejection, when the
microphone is connected differentially to the device.
SP-
8
Speaker Negative : The SP-, Class D PWM output,
provides a differential output with SP+ pin to drive 8Ω
speaker or buzzer. During power down or recording, this pin
is tri-stated.
VSSP
9
PWM Ground: VSSP is the ground for PWM speaker driver.
It is important to have a separate path for each ground back
to the system ground terminal to minimize noise.

AGC
12
Analog power supply: It is important to have a separate
path for each power back to the power terminal to minimize
the noises. Decoupling capacitors to VSSA should be as
close to the device as possible.
VCCP: Power supply for PWM speaker drivers. It is important
to have a separate path for each power back to the power
terminal to minimize noise. Decoupling capacitors to VSSP
should be as close to the device as possible.
Speaker Positive : The SP+, Class D PWM output, provide
a differential output with SP- pin to drive an 8Ω speaker or
buzzer directly. During power down or recording, this pin is
tri-stated.
Automatic Gain Control: The AGC dynamically adjusts the
gain of the preamplifier to compensate the wide range of
microphone input levels. The AGC allows the full range of
signal to be recorded with minimal distortion. Nominal
values of 4.7 µF give satisfactory results in most cases.
Connecting this pin to ground provides maximum gain to the
preamplifier circuitry. Conversely, connecting this pin to
power supply provides minimum gain to the preamplifier
circuitry.
AUD
13
AUD: The AUD provides a single-ended current output to
drive an external amplifier. During standby or recording, this
pin is tri-stated.
ROSC
14
Oscillator Resistor: This enables the user to vary the
record and/or playback duration of the device. A resistor
connected between the ROSC pin and VSSA determines the
sample frequency for the ISD1600B device. Please refer to
the Duration Section in Section 6.1.
VCCD
15
LED
16
Digital power supply: It is important to have a separate
path for each power back to the power terminal to minimize
noise. Decoupling capacitors should be as close to the
device as possible.
LED output: This pin is Low during a record cycle and
blinks during playback cycle. It can be used to drive an LED
to indicate either a record or playback cycle is in progress.

6. FUNCTIONAL DESCRIPTION
6.1. DETAILED DESCRIPTION
6.1.1 Audio Quality
Nuvoton’s patented ChipCorder® MLS technology provides natural high quality record and
playback solution on a single chip. The input audio signals are stored directly into the nonvolatile memory and are reproduced in its natural form without any compression artifacts
caused by the digital speech solutions. A complete sample is stored in a single cell,
minimizing the memory needed to store a single message.
6.1.2 Duration
The ISD1600B series offer single-chip solution with record & playback duration from 6.6
seconds to 40 seconds. Sampling frequency and duration are determined by an external
resistor connected to the Rosc pin.

6.1.3 Flash Storage
The ISD1600B product utilizes the on-chip Flash memory providing zero-power message
storage. The message is retained for up to 100 years without power. In addition, the device
can be re-recorded typically over 100,000 times.
6.1.4 Basic Operation
The ISD1600B ChipCorder® device is controlled by either the REC , or one of the two
playback modes, PLAYE and PLAYL . The ISD1600B parts are configured for simple design
in single-message application. Detailed operations are explained in Section 6.2.
6.1.5 Automatic Power-Down Mode
At the end of a playback or record cycle, the ISD1600B device automatically enters into a lowpower mode, consuming typically 1µA, provided that PLAYE , PLAYL and REC are High
(see DC parameters Section). During a playback cycle, the device powers down automatically
at the end of the message. During a record cycle, the device powers down immediately after
REC is released to High.
6.2. FUNCTIONAL DESCRIPTION EXAMPLE
The following example operating sequences demonstrate the functionality of the ISD1600B series.

Publication Release Date: Dec. 01, 2008
Revision 1.22
ISD1600B SERIES
6.2.1. Record a Message
The device starts recording from the beginning of the memory when REC transits from High
to Low and stays at Low. A record cycle is completed when REC is pulled to High or entire
memory is filled up. Then an End-of-Message (EOM) marker is written at the end of message,
enabling a subsequent playback cycle to terminate appropriately. Hence, the device
automatically enters into standby mode.
Record takes precedence over playback operation. If REC is pulled Low during a playback
cycle, the playback immediately halts and recording starts from the beginning of the memory.
Holding REC Low after recording will increase standby current consumption.
6.2.2. Edge-trigger Playback
A playback operation starts from the beginning of the memory when PLAYE detects a low
going signal exceeding the specified debounced time. Playback continues until an EOM
marker is encountered. Upon completion of a playback cycle, the device automatically enters
into standby mode.
During playback, a subsequent low going signal will terminate the current playback operation.
Holding this pin Low after playback operation will increase standby current consumption.
6.2.3. Level- trigger Playback
When PLAYL switches from High to Low and stays at Low, a playback starts from the
beginning of the memory until either an EOM marker is reached, then it automatically powers
down.
If PLAYL is pulled High at any time during playback, the playback operation stops
immediately and the device enters into the power-down mode.
6.2.4. LED Operation
The LED is Low during recording, which turns on an LED as a recording indicator. However,
during playback, the LED blinks a few times per second to indicate a playback operation. It
returns to a High when operation stops.
6.2.5. ROSC Operation
The duration can be varied by changing the value of ROSC. This means the designer has the
flexibility to choose different sampling frequency, up to 12 KHz, depending upon the needs.
This feature allows frequency shifting where a recorded audio can be played back faster or
slower than normal for special sound effects.
Another feature is a “Pause” function that can be activated by taking the ROSC resistor to VCC to
stop playback momentarily, and to resume when the resistor is switched back to ground.

Notes:
*
These components may be needed in order to optimize for the best voice quality and system performance,
which is also dependent upon the layout of the PCB. Pending upon system requirement, Cx can be 10 μF, 4.7
μF or other values. For R7, 1kΩ gives satisfactory result fro most cases.
** For Sampling Freq at 8 kHz, R4 = 80 KΩ
*** It is important to have a separate path for each ground and power back to related terminal to minimize the
