6. PIN DESCRIPTION
PIN NAME PIN NO. FUNCTION
A0-A7 1-6, 9, 10 Address Inputs: The address inputs have two functions,
depending on the level of the two Most Significant Bits (MSB)
of the address (A6 and A7).
If either or both of the two MSBs are LOW, all inputs are
interpreted as address bits and are used as the start address
for the current record or playback cycle. The address pins are
inputs only and do not output internal address information as
the operation progresses. Address inputs are latched by the
falling edge of PLAYE , PLAYL , or REC .
If both A6 & A7 are HIGH, then the device is in special
operational modes. Please refer to operational modes section
for details.
VSSA, VSSD 12, 13
Ground: Similar to VCCA and VCCD, separate analog and digital
ground rails provide independent analog and digital ground
buses internally to minimize noise. These pins should be tied
together as close as possible to the device.
SP+, SP- 14, 15 Speaker Outputs: The differential SP+ and SP- pins are
designed to drive a 16Ω speaker and no coupling capacitor is
required. Conversely, with single-ended connection, a
coupling capacitor is needed between the SP pin and the
speaker. Besides, the output power is about a quarter of that
from differential output. The speaker outputs are in high-
impedance state during recording and at VSSA during power
down.
VCCA, VCCD 16, 28
Supply Voltages: Separate analog and digital power rails
provide power to internal analog and digital circuits
respectively to minimize internal noises. These power buses
are brought out to separate pads and should be tied together
as close to the supply source as possible. It is important that
the power supplies are decoupled as close to the device as
possible.
MIC 17
Microphone: The microphone input transfers its signal to the
on-chip preamplifier. An on-chip Automatic Gain Control
(AGC) circuit controls the gain of this preamplifier from –15 to
24dB. An external microphone should be AC coupled to this
pin via a series capacitor. The capacitor value, together with
the internal 10 KΩ resistance on this pin, determines the low-
frequency cutoff for the device passband. See Winbond’s
Application Information for additional information on low-
frequency cutoff calculation.
ISD1200 SERIES
Publication Release Date: April 21, 2005
- 7 - Revision 1.1
PIN NAME PIN NO. FUNCTION
MIC REF 18 Microphone Reference: The MIC REF input is the inverting
input to the microphone preamplifier. This provides a noise-
canceling or common-mode rejection input to the device when
connected to a differential microphone.
AGC 19
Automatic Gain Control (AGC): The AGC input dynamically
adjusts the gain of the preamplifier to compensate for the wide
range of microphone input levels. The AGC allows the full
range of sound, from whispers to loud sounds, to be recorded
with minimal distortion. The “attack” time is determined by the
time constant of a 5 KΩ internal resistance and an external
capacitor (C6 of Figure 5 in Section 11) connected from the
AGC pin to VSSA. The “release” time is determined by the time
constant of an external resistor (R5) and an external capacitor
(C6) connected in parallel between the AGC pin and VSSA pin.
Nominal values of 470 KΩ and 4.7 µF give satisfactory results
in most cases. Tying this to ground gives maximum gain,
while tying it to VCCA gives minimum gain for the AGC
amplifier.
ANA IN 20 Analog Input: The ANA IN transfers an input signal to the
chip for recording. For microphone usage, this ANA IN pin
should be connected via an external capacitor to the ANA
OUT pin. This capacitor value, together with the 3 KΩ input
impedance of ANA IN, is selected to give additional cutoff at
the low-frequency end of the voice passband. If the desired
input is derived from a source other than a microphone, the
signal can be capacitively coupled into the ANA IN pin directly.
ANA OUT 21 Analog Output: This pin provides the preamplifier output to
the user. The voltage gain of the preamplifier is determined by
the voltage level at the AGC pin.
PLAYL [2] 23 Playback, Level-Activated: When this input signal is held
LOW, a playback cycle is initiated, and playback continues
until PLAYL is pulled HIGH, or an EOM marker is detected.
The device automatically powers down and enters into
standby mode upon completion of a playback cycle.
PLAYE [2] 24 Playback, Edge-Activated: When a LOW-going transition is
detected on this pin, a playback cycle begins. Taking PLAYE
HIGH during a playback cycle will not terminate the current
cycle. Playback continues until an EOM is encountered. Upon
completion of a playback cycle, the device automatically
powers down and enters into standby mode.
ISD1200 SERIES

PIN NAME PIN NO. FUNCTION
RECLED 25 Record LED: The RECLED output is LOW during a record
cycle. It can be used to drive an LED to indicate a record cycle
is in progress. In addition, RECLED pulses LOW
momentarily when an end-of-message is encountered in a
playback operation.
XCLK 26
External Clock: The external clock input has an internal pull-
down resistor. The ISD1100 is configured at the factory with
an internal sampling clock frequency that guarantees its
minimum nominal record/playback time. For instance, an
ISD1110 operating within specification will be observed to
always have a minimum of 10 seconds of recording time. The
sampling frequency is then maintained to a variation of ±2.25
percent over the commercial temperature and operating
voltage ranges while still maintaining the minimum duration
specified. As a result some devices will have a few percent
more than nominal recording time. If greater precision is
required, the device can be clocked through the XCLK pin as
follows:
EXTERNAL CLOCK SAMPLE RATES
Part Number Sample Rate Required Clock
ISD1110 6.4 kHz 819.2 kHz
ISD1112 5.3 kHz 682.7 kHz
These recommended clock rates should not be varied
because the anti-aliasing and smoothing filters are fixed, and
aliasing problems can occur if the sample rate differs from the
one recommended. The duty cycle on the input clock is not
critical, as the clock is immediately divided by two. If the
XCLK is not used, this pin must be grounded. Please see
Application Information for the ISD1100 series for more details
on external clocking.

PIN NAME PIN NO. FUNCTION
REC [1] 27 Record: The REC input is an active-LOW signal. The device
records whenever REC is LOW. This signal must remain
LOW for the duration of the recording. A record cycle is
completed when REC is pulled HIGH or the memory space
is filled up.
REC takes precedence over either playback ( PLAYE or
PLAYL ) signal. If REC is pulled LOW during a playback
cycle, the playback immediately ceases and recording begins.
An end-of-message (EOM) marker is internally recorded,
enabling a subsequent playback cycle to terminate
appropriately. The device automatically powers down into
standby mode when REC goes HIGH.
NC 11
NC: No connect
Notes:
[1] The REC signal is debounced for 50 ms on the rising edge to prevent a false retriggering from a push-
button switch.
[2] During playback, if either PLAYE or PLAYL is held LOW during EOM or OVF, the device will still
enter into standby mode and the internal oscillator and timing generator will stop. However, the rising
edge of PLAYE and PLAYL are not debounced and any subsequent falling edge (particularly switch
bounce) present on the input pins will initiate another playback.

7. FUNCTIONAL DESCRIPTION
7.1. DETAILED DESCRIPTION
Speech/Sound Quality
Winbond’s patented ChipCorder® technology provides natural audio record and playback. The
ISD1200 series includes devices offered at 5.3 and 6.4 kHz sampling frequencies, allowing the user a
choice of speech quality options. The input voice signals are stored directly in nonvolatile EEPROM
cells and are reproduced without the synthetic effect often heard with digital solid-state speech
solutions. A complete sample is stored in a single cell, minimizing the memory necessary to store a
recording of a given duration.
Duration
To meet end system requirements, the ISD1200 series offers single-chip solutions at 10 and 12
seconds.

* 3dB roll-off-point….
EEPROM Storage
One of the benefits of Winbond’s ChipCorder® technology is the use of on-chip non-volatile memory,
providing zero-power message storage. The message is retained for up to 100 years typically without
power. In addition, the device can be re-recorded typically over 100,000 times.
Basic Operation
The ISD1200 ChipCorder® series devices are controlled by a single record signal, REC , and either of
two push-button control playback signals, PLAYE (edge-activated playback), and PLAYL (level-
activated playback). The ISD1200 series parts are configured for simplicity of design in a
single/multiple-message application. Using the address lines will allow multiple message applications.
Automatic Power-Down Mode
At the end of a playback or record cycle, the ISD1200 series devices automatically return to a low-
power standby mode, consuming typically 0.5 µA. 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 pulled HIGH.

Addressing
In addition to single message application, the ISD1200 series provides a full addressing capability.
The ISD1200 series storage array has 80 distinct addressable segments, providing the following
resolutions per segment. See Application Information for ISD1200 address tables.

7.2. OPERATIONAL MODES
The ISD1200 series is designed with several built-in operational modes provided to allow maximum
functionality with a minimum of additional components, described in details below. The operational
modes use the address pins on the ISD1200 devices, but are mapped outside the valid address
range. When the two Most Significant Bits (MSBs) are HIGH (A6 and A7), the remaining address
signals are interpreted as mode bits and not as address bits. Therefore, operational modes and direct
addressing are not compatible and cannot be used simultaneously.
There are two important considerations for using operational modes. Firstly, all operations begin
initially at address 0, which is the beginning address of the ISD1200. Later operations can begin at the
other address locations, depending on the operational mode(s) chosen. In addition, the address
pointer is reset to 0 when the device is changed from record to playback but not from playback to
record when A4 is HIGH in Operational Mode.
Secondly, an Operational Mode is executed when any of the control inputs, PLAYE , PLAYL , or
REC , go LOW and the two MSBs are HIGH. This Operational Modes remains in effect until the next
LOW-going control input signal, at which point the current address/mode levels are sampled and
executed.
Note: The two MSBs (A6 & A7) are pins 9 and 10 for ISD1200 series.

7.2.1. Operational Modes Description
The Operational Modes can be used in conjunction with a microcontroller, or they can be hardwired to
provide the desired system operation.
A0 – Message Cueing
Message Cueing allows the user to skip through messages, without knowing the actual physical
address of each message. Each control input LOW pulse causes the internal address pointer to skip
to the next message. This mode should be used for playback only, and is typically used with A4
Operational Mode.
A1 – Delete EOM Markers
The A1 Operational Modes allows sequentially recorded message to be combined into a single
message with only one EOM marker set at the end of the final message. When this operational mode
is configured, messages recorded sequentially are played back as one continuous message.
A2 – Unused
A3 – Message Looping
The A3 Operational Mode allows for the automatic, continuously repeated playback of the message
located at the beginning of the address space.
A Message can completely fill the ISD1200 device and will loop from beginning to end. Pulsing
PLAYE will start the playback and pulsing PLAYL wil end the playback.
A4 – Consecutive Addressing
During normal operations, the address pointer will reset when a message is played through to an
EOM marker. The A4 Operational Mode inhibits the address pointer reset, allowing messages to be
recorded or played back consecutively. When the device is in a static state; i.e., not recording or
playing back, momentarily taking this pin LOW will reset the address counter to zero.
A5 – Unused

Functional Description Example
The following example operating sequence demonstrates the functionality of the ISD1200 series
devices.
1. Record a message:
Pulling the REC signal LOW initiates a record cycle from current location. When REC is
held LOW, the recording continues. Until the memory array is filled up or when REC is
pulled HIGH, recording ceases. An EOM marker is written at the end of message. Then the
device will automatically power down.
2. Edge-activated playback:
Pulling the PLAYE signal LOW initiates a playback cycle from the beginning of the message
until the entire message is played. The rising edge of PLAYE has no effect on operation.
When the EOM marker is encountered, the device automatically powers down. A subsequent
falling edge on PLAYE initiates a new playback operation from the beginning of the
message.
3. Level-activated playback:
Holding the PLAYL signal LOW initiates a playback cycle from the beginning of the
message, until PLAYL is pulled HIGH or when the EOM marker is encountered, playback
operation stops and the device automatically powers down.
4. Record (interrupting playback).
The REC signal takes precedence over playback operation. Holding REC LOW initiates a
new record operation from current location, regardless of any current operation in progress.
5. RECLED operation.
During record, the RECLED output pin provides an active-LOW signal, which can be used to
drive an LED as a “record-in-progress” indicator. It returns to a HIGH state when the REC
pin is pulled HIGH or when the recording is completed due to the memory being filled.
However, during playback, this pin also pulses LOW to indicate an EOM at the end of a
message.

Applications Note
Some users may experience an unexpected recording taking place when their circuit is powered up,
or the batteries are changed and VCC rises faster than REC . This undesired recording prevents
playback of the previously recorded message. A spurious EOM marker appears at the very beginning
of the memory, preventing access to the original message, and nothing is played.
To prevent this occurrence, place a capacitor (approx. 0.001 µF) between the control pin, REC , and
VCC. This pulls the control pin voltage up with VCC as it rises. Once the voltage is HIGH, the pull-up
device will keep the pin HIGH until intentionally pulled LOW, preventing the false EOM marker.
Since this anomaly depends on factors such as the capacitance of the user’s printed circuit board, not
all circuit designs will exhibit the spurious marker. However, it is recommended, that the capacitor is
included for design reliability. A more detailed explanation and resolution of this occurrence is
described in Application Information.
