Address/Mode Inputs: The Address/Mode Inputs have two
functions depending on the level of the two Most Significant Bits
(MSB) of the address pins (A8 and A9).
If either or both of the two MSBs are LOW, the inputs are all
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 any internal address information during the
operation. Address inputs are latched by the falling edge of CE.
If both MSBs are HIGH, the Address/Mode inputs are interpreted as
Mode bits according to the Operational Mode table on page 12.
There are six operational modes (M0…M6) available as indicated in
the table. It is possible to use multiple operational modes
simultaneously. Operational Modes are sampled on each falling
edge of CE, and thus Operational Modes and direct addressing
are mutually exclusive.
AUX IN

The Auxiliary Input is multiplexed through to the
Auxiliary Input:
output amplifier and speaker output pins when CE is HIGH, P/R
is HIGH, and playback is currently not active or if the device is in
playback overflow. When cascading multiple ISD2500 devices, the
AUX IN pin is used to connect a playback signal from a following
device to the previous output speaker drivers. For noise
considerations, it is suggested that the auxiliary input not be driven
when the storage array is active.

Ground: The ISD2500 series of devices utilizes separate analog
and digital ground busses. These pins should be connected
separately through a low-impedance path to power supply ground.

chip differential speaker driver, capable of driving 50 mW into 16 Ω
from AUX IN (12.2mW from memory).
[1]
The speaker outputs are held at VSSA levels during record and
power down. It is therefore not possible to parallel speaker outputs
of multiple ISD2500 devices or the outputs of other speaker drivers.
[2] A single-end output may be used (including a coupling capacitor
between the SP pin and the speaker). These outputs may be used
individually with the output signal taken from either pin. However,
the use of single-end output results in a 1 to 4 reduction in its
output power.

[2]
Connection of speaker outputs in parallel may cause damage to the device.
Never ground or drive an unused speaker output.

Supply Voltage: To minimize noise, the analog and digital circuits
in the ISD2500 series devices use separate power busses. These
voltage busses are brought out to separate pins and should be tied
together as close to the supply as possible. In addition, these
supplies should be decoupled as close to the package as possible.
Microphone: The microphone pin transfers input signal to the on-
chip preamplifier. A built-in 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 ISD2500 series
passband. See Winbond’s Application Information for additional
information on low-frequency cutoff calculation.

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.
: The AGC dynamically adjusts the gain of
Automatic Gain Control
the preamplifier to compensate for the wide range of microphone
input levels. The AGC allows the full range of 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 (C2 on the schematic of Figure 5 in section
11) connected from the AGC pin to VSSA analog ground. The
“release” time is determined by the time constant of an external
resistor (R2) and an external capacitor (C2) connected in parallel
between the AGC pin and VSSA analog ground. Nominal values of
470 KΩ and 4.7 µF give satisfactory results in most cases.
ANA IN

Analog Input: The analog input transfers analog signal to the chip
for recording. For microphone inputs, the ANA OUT pin should be
connected via an external capacitor to the ANA IN pin. This
capacitor value, together with the 3.0 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 fed, capacitively
coupled, into the ANA IN pin directly.
ANA OUT
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.

Overflow: This signal pulses LOW at the end of memory array,
OVF
indicating the device has been filled and the message has
overflowed. The OVF output then follows the CE input until a
PD pulse has reset the device. This pin can be used to cascade
several ISD2500 devices together to increase record/playback
durations.
CE
PD
Chip Enable: The CE input pin is taken LOW to enable all
playback and record operations. The address pins and
playback/record pin (P/R ) are latched by the falling edge of CE.
CE has additional functionality in the M6 (Push-Button)
Operational Mode as described in the Operational Mode section.
Power Down: When neither record nor playback operation, the PD
pin should be pulled HIGH to place the part in standby mode (see
ISB specification). When overflow ( OVF ) pulses LOW for an
overflow condition, PD should be brought HIGH to reset the
address pointer back to the beginning of the memory array. The PD
pin has additional functionality in the M6 (Push-Button) Operation
Mode as described in the Operational Mode section.

End-Of-Message: A nonvolatile marker is automatically inserted at
EOM
the end of each recorded message. It remains there until the
message is recorded over. The EOM output pulses LOW for a
period of TEOM at the end of each message.
In addition, the ISD2500 series has an internal VCC detect circuit to
maintain message integrity should VCC fall below 3.5V. In this case,
EOM goes LOW and the device is fixed in Playback-only mode.
When the device is configured in Operational Mode M6 (Push-
Button Mode), this pin provides an active-HIGH signal, indicating
the device is currently recording or playing. This signal can
conveniently drive an LED for visual indicator of a record or
playback operation in process.

External Clock: The external clock input has an internal pull-down
device. The device is configured at the factory with an internal
sampling clock frequency centered to ±1 percent of specification.
The frequency is then maintained to a variation of ±2.25 percent
over the entire commercial temperature and operating voltage
ranges. If greater precision is required, the device can be clocked
through the XCLK pin as follows:
Part Number

682.7 kHz

4.0 kHz
These recommended clock rates should not be varied because the
antialiasing 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 input
must be connected to ground.

P/R
Playback/Record: The P/R input pin is latched by the falling edge
of the CE pin. A HIGH level selects a playback cycle while a LOW
level selects a record cycle. For a record cycle, the address pins
provide the starting address and recording continues until PD or
CE is pulled HIGH or an overflow is detected (i.e. the chip is full).
When a record cycle is terminated by pulling PD or CE HIGH,
then End-Of-Message ( EOM ) marker is stored at the current
address in memory. For a playback cycle, the address inputs
provide the starting address and the device will play until an EOM
marker is encountered. The device can continue to pass an EOM
marker if CE is held LOW in address mode, or in an Operational
Mode. (See Operational Modes section)

7. FUNCTIONAL DESCRIPTION
7.1. DETAILED DESCRIPTION
Speech/Sound Quality
The Winbond’s ISD2500 series includes devices offered at 4.0, 5.3, 6.4, and 8.0 kHz sampling
frequencies, allowing the user a choice of speech quality options. Increasing the duration within a
product series decreases the sampling frequency and bandwidth, which affects the sound quality.
Please refer to the ISD2560/75/90/120 Product Summary table below to compare the duration,
sampling frequency and filter pass band.
The speech samples are stored directly into the on-chip nonvolatile memory without any digitization
and compression associated like other solutions. Direct analog storage provides a very true, natural
sounding reproduction of voice, music, tones, and sound effects not available with most solid state
digital solutions.
Duration
To meet various system requirements, the ISD2560/75/90/120 products offer single-chip solutions at
60, 75, 90, and 120 seconds. Parts may also be cascaded together for longer durations.

EEPROM Storage
One of the benefits of Winbond’s ChipCorder® technology is the use of on-chip nonvolatile 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.
Microcontroller Interface
In addition to its simplicity and ease of use, the ISD2500 series includes all the interfaces necessary
for microcontroller-driven applications. The address and control lines can be interfaced to a
microcontroller and manipulated to perform a variety of tasks, including message assembly, message
concatenation, predefined fixed message segmentation, and message management.
- 10 -
ISD2560/75/90/120
Programming
The ISD2500 series is also ideal for playback-only applications, where single or multiple messages
are referenced through buttons, switches, or a microcontroller. Once the desired message
configuration is created, duplicates can easily be generated via a gang programmer.
7.2. OPERATIONAL MODES
The ISD2500 series is designed with several built-in Operational Modes that provide maximum
functionality with minimum external components. These modes are described in details as below. The
Operational Modes are accessed via the address pins and mapped beyond the normal message
address range. When the two Most Significant Bits (MSB), A8 and A9, are HIGH, 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. First, all operations begin initially
at address 0 of its memory. Later operations can begin at 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, playback to record (except M6 mode), or when a Power-Down cycle is
executed.
Second, Operational Modes are executed when CE goes LOW. This Operational Mode remains in
effect until the next LOW-going CE signal, at which point the current mode(s) are sampled and
executed.

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.
M0 – Message Cueing
Message Cueing allows the user to skip through messages, without knowing the actual physical
addresses of each message. Each CE LOW pulse causes the internal address pointer to skip to the
next message. This mode is used for playback only, and is typically used with the M4 Operational
Mode.
M1 – Delete EOM Markers
The M1 Operational Mode allows sequentially recorded messages 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.
M2 – Unused
When Operational Modes are selected, the M2 pin should be LOW.
M3 – Message Looping
The M3 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 ISD2500 device and
will loop from beginning to end without OVF going LOW.
M4 – Consecutive Addressing
During normal operation, the address pointer will reset when a message is played through an EOM
marker. The M4 Operational Mode inhibits the address pointer reset on EOM , allowing messages to
be played back consecutively.
M5 - CE-Level Activated
The default mode for ISD2500 devices is for CE to be edge-activated on playback and level-
activated on record. The M5 Operational Mode causes the CE pin to be interpreted as level-
activated as opposed to edge-activated during playback. This is especially useful for terminating
playback operations using the CE signal. In this mode, CE LOW begins a playback cycle, at the
beginning of the device memory. The playback cycle continues as long as CE is held LOW. When
CE goes HIGH, playback will immediately end. A new CE LOW will restart the message from the
beginning unless M4 is also HIGH.
- 12 -
ISD2560/75/90/120
M6 – Push-Button Mode
The ISD2500 series contain a Push-Button Operational Mode. The Push-Button Mode is used
primarily in very low-cost applications and is designed to minimize external circuitry and components,
thereby reducing system cost. In order to configure the device in Push-Button Operational Mode, the
two most significant address bits must be HIGH, and the M6 mode pin must also be HIGH. A device in
this mode always powers down at the end of each playback or record cycle after CE goes HIGH.
When this operational mode is implemented, three of the pins on the device have alternate
functionality as described in the table below.
TABLE 3: ALTERNATE FUNCTIONALITY IN PINS
Pin Name
Alternate Functionality in Push-Button Mode
Start/Pause Push-Button (LOW pulse-activated)
CE
PD
Stop/Reset Push-Button (HIGH pulse-activated)
Active-HIGH Run Indicator
EOM
CE (START/PAUSE)
In Push-Button Operational Mode, CE acts as a LOW-going pulse-activated START/PAUSE signal.
If no operation is currently in progress, a LOW-going pulse on this signal will initiate a playback or
record cycle according to the level on the P/R pin. A subsequent pulse on the CE pin, before an
EOM is reached in playback or an overflow condition occurs, will pause the current operation, and
the address counter is not reset. Another CE pulse will cause the device to continue the operation
from the place where it is paused.
PD (STOP/RESET)
In Push-Button Operational Mode, PD acts as a HIGH-going pulse-activated STOP/RESET signal.
When a playback or record cycle is in progress and a HIGH-going pulse is observed on PD, the
current cycle is terminated and the address pointer is reset to address 0, the beginning of the
message space.
EOM (RUN)
In Push-Button Operational Mode, EOM becomes an active-HIGH RUN signal which can be used to
drive an LED or other external device. It is HIGH whenever a record or playback operation is in
progress.
Recording in Push-Button Mode
1. The PD pin should be LOW, usually using a pull-down resistor.

Revision 1.0
ISD2560/75/90/120
2. The P/R pin is taken LOW.
3. The CE pin is pulsed LOW. Recording starts, EOM goes HIGH to indicate an
operation in progress.
4. When the CE pin is pulsed LOW. Recording pauses, EOM goes back LOW. The
internal address pointers are not cleared, but the EOM marker is stored in memory to
indicate as the message end. The P/ R pin may be taken HIGH at this time. Any
subsequent CE would start a playback at address 0.
5. The CE pin is pulsed LOW. Recording starts at the next address after the previous set
EOM marker. EOM goes back HIGH.[3]
6. When the recording sequences are finished, the final CE pulse LOW will end the last
record cycle, leaving a set EOM marker at the message end. Recording may also be
terminated by a HIGH level on PD, which will leave a set EOM marker.
Playback in Push-Button Mode
1. The PD pin should be LOW.
2. The P/R pin is taken HIGH.
3. The CE pin is pulsed LOW. Playback starts, EOM goes HIGH to indicate an operation
in progress.
4. If the CE pin is pulsed LOW or an EOM marker is encountered during an operation,
the part will pause. The internal address pointers are not cleared, and EOM goes back
LOW. The P/R pin may be changed at this time. A subsequent record operation would
not reset the address pointers and the recording would begin where playback ended.
5. CE is again pulsed LOW. Playback starts where it left off, with EOM going HIGH to
indicate an operation in progress.
6. Playback continues as in steps 4 and 5 until PD is pulsed HIGH or overflow occurs.
7. If in overflow, pulling CE LOW will reset the address pointer and start playback from the
beginning. After a PD pulse, the part is reset to address 0.
Note: Push-Button Mode can be used in conjunction with modes M0, M1, and M3.
[3]
If the M1 Operational Mode pin is also HIGH, the just previously written EOM bit is erased, and recording starts at that
address.

ISD2560/75/90/120
Notes for Push-Button modes:
1. A9, A8, and A6 = 1 for push-button operation.
2. The first CE LOW pulse performs a start function.
3. The part will begin to play or record after a power-up delay TPUD
.
4. The part must have CE HIGH for a debounce period TDB before it will recognize another falling edge of
CE and pause.
5. The second CE LOW pulse, and every even pulse thereafter, performs a Pause function.
6. Again, the part must have CE HIGH for a debounce period TDB before it will recognize another falling
edge of CE , which would restart an operation. In addition, the part will not do an internal power down
until CE is HIGH for the TDB time.
7. The third CE LOW pulse, and every odd pulse thereafter, performs a Resume function.
8. At any time, a HIGH level on PD will stop the current function, reset the address counter, and power
down the device.

Low-frequency cutoff depends upon the value of external capacitors (see Pin Descriptions)
From AUX IN; if ANA IN is driven at 50 mV p-p, the POUT = 12.2 mW, typical.
With 5.1 K Ω series resistor at ANA IN.
TPDS is required during a static condition, typically overflow.
Sampling Frequency and playback Duration can vary as much as ±2.25 percent over the commercial temperature range.
For greater stability, an external clock can be utilized (see Pin Descriptions)
[8]
Filter specification applies to the antialiasing filter and the smoothing filter. Therefore, from input to output, expect a 6 dB
drop by nature of passing through both filters.

FIGURE 6: ISD2560/75/90/120 APPLICATION EXAMPLE – MICROCONTROLLER/ISD2500
INTERFACE
In this simplified block diagram of a microcontroller application, the Push-Button Mode and message
cueing are used. The microcontroller is a 16-pin version with enough port pins for buttons, an LED,
and the ISD2500 series device. The software can be written to use three buttons: one each for play
and record, and one for message selection. Because the microcontroller is interpreting the buttons
and commanding the ISD2500 device, software can be written for any function desired in a particular
application.
Note: Winbond does not recommend connecting address lines directly to a microprocessor bus.
Address lines should be externally latched.
