DETAILED DESCRIPTION
SPEECH/SOUND QUALITY
ISD's patented ChipCorder technology provides
natural record and playback. The input voice signals
are stored directly in nonvolatile cells and are re-
produced without the synthetic effect often heard
with digital solid-state speech solutions. A complete
sample is stored in a single cell, minimizing the mem-
ory necessary to store a single message.
DURATION
The ISD1810 devices offer single-chip solutions
with 8 to 16 seconds of record/playback duration
capacity. Sampling rate and duration are deter-
mined by an external resistor connected to the
ROSC pin. These specifications apply with the re-
quired resistor value for 10-second minimum play-
back duration.
NOTE
Only the 10 second duration is guaranteed
and tested.
NONVOLATILE STORAGE
One of the benefits of ISD's ChipCorder technology
is the use of on-chip nonvolatile memory, providing
zero-power message storage. The message is re-
tained for up to 100 years without power. In addi-
tion, the device can be re-recorded typically over
10,000 times.
BASIC OPERATION
The ISD1810 ChipCorder device is controlled by
the REC pin, and either of two playback pins,
PLAYE (edge-activated playback), and PLAYL (lev-
el-activated playback). The ISD1810 parts are
configured for design simplicity in a single-mes-
sage application. Device operation is explained
on "Functional Description Example" on page 6.
AUTOMATIC POWER-DOWN MODE
At the end of a playback or record cycle, the
ISD1810 device automatically returns to a low-
power standby mode, consuming typically
0.5 A, provided that Play REC, XCLK, and FT pins
are LOW (see DC parameters). 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 LOW.
PIN DESCRIPTIONS
VOLTAGE SUPPLIES (V
CCA
, V
CCD
)
Analog and digital circuits internal to the ISD1810
device use separate power buses to minimize
noise on the chip. These power buses are brought
out to separate pins on the package and should
be tied together as close to the supply as possi-
ble. It is important that the power supply be de-
coupled as close as possible to the package.
GROUND SUPPLIES (V
SSA
, V
SSD
)
Similar to V
CCA
and V
CCD
, the analog and digital
circuits internal to the ISD1810 device use sepa-
rate ground buses to minimize noise. These pins
should be tied together as close as possible to the
device.
RECORD (REC)
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 record-
ing. 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.
NOTE
The REC signal is internally debounced on
the rising edge to prevent a false re-triggering
from a push-button switch.

TM
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 automatical-
ly 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.
PLAYBACK, EDGE-ACTIVATED (PLAYE)
When a HIGH-going transition is detected on this
input pin, a playback cycle begins. Playback con-
tinues until an End-of-Message (EOM) marker is en-
countered or the end of the memory space is
reached. Upon completion of the playback cy-
cle, the device automatically powers down into
standby mode. Taking PLAYE LOW during a play-
back cycle will not terminate the current cycle.
This pin has an internal pull-down device. Holding
this pin HIGH will increase standby current con-
sumption.
PLAYBACK, LEVEL-ACTIVATED (PLAYL)
When this input pin transitions from LOW to HIGH, a
playback cycle is initiated. Playback continues
until PLAYL is pulled LOW, an end-of-message
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.
RECORD LED OUTPUT (RECLED)
The RECLED output is LOW during a record cycle.
It can be used to drive an LED to provide feed-
back that a record cycle is in progress. In addition,
RECLED pulses LOW momentarily when an end-of-
message or end-of-memory marker is encoun-
tered in a playback cycle.
MICROPHONE INPUT (MIC)
The microphone input transfers its signal to the on-
chip preamplifier. An on-chip 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 the internal 10 K
resistance on this pin, determine the low-frequency
cutoff for the ISD1810 passband.
MICROPHONE REFERENCE (MIC REF)
The MIC REF input is the inverting input to the mi-
crophone preamplifier. This provides input noise-
cancellation, or common-mode rejection, when
the microphone is connected differentially to the
device.
Figure 1:
ISD1810 Pinouts--For Sampling
Only
NOTE:
NC means must Not Connect.
AUTOMATIC GAIN CONTROL (AGC)
The AGC 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. Nominal val-
ues of 4.7 F give satisfactory results in most cas-
es.

ISD
SPEAKER OUTPUTS (SP+, SP)
The SP+ and SP pins provide direct drive for loud-
speakers with impedances as low as 8
. A single
output may be used, but, for direct-drive loud-
speakers, the two opposite-polarity outputs pro-
vide an improvement in output power of up to four
times over a single-ended connection. Furthermore,
when SP+ and SP are used, a speaker coupling
capacitor is not required. A single-ended connec-
tion will require an AC-coupling capacitor be-
tween the SP pin and the speaker.
The SP+ pin and the SP pin are internally connected
through a 50 K
resistance. When not in playback
mode, they are floating.
EXTERNAL CLOCK (XCLK)
The external clock input for the ISD1810 devices
has an internal pull-down resistor. This pin is used
for test purposes only. Do not bond this pad.
RESISTOR CONTROLLED OSCILLATOR (ROSC)
The resistor controlled oscillator input enables the
user to vary the ISD1810 device record and play-
back duration. The resistor connected between
the ROSC pin and V
SS
(R2) determines the sample
frequency and the filter upper pass band for the
ISD1810 device. ISD recommends an ROSC resis-
tor value of 100 K
.
FEED THROUGH (FT)
Feed Through mode allows use of the speaker
drivers for external signals. The signal between the
MIC and MIC_REF pins will pass through the AGC,
the filter and the speaker drivers to the speaker
outputs SP+ and SP-. The input FT controls the feed
through mode. To operate this mode, the control
pins REC, PLAYE and PLAYL are held low at VSS. The
pin FT is held high to VCC. For normal operation of
record, play and power down, the FT pin is held at
VSS. The FT pin has a weak pull down to VSS.

FUNCTIONAL DESCRIPTION EXAMPLE
The following example operating sequence dem-
onstrates the functionality of the ISD1810 devices.
1.
Record a message filling the memory.
Pulling the REC pin HIGH initiates a record
cycle from the beginning of the message
space. The device will automatically power
down after REC is released LOW. An EOM
marker is written at the end of message. If
REC is held HIGH, the recording continues
until the message space has been filled.
Once the message space is filled,
recording ceases.
2.
Edge-activated playback.
Pulling the PLAYE pin HIGH initiates a
playback cycle from the beginning of the
message space. The falling edge of PLAYE
has no effect on operation. When the
device reaches the EOM marker, it
automatically powers down. If a recording
has filled the message space, the entire
message is played. A subsequent rising
edge on PLAYE initiates a new play cycle
from the beginning of the memory.
3.
Level-activated playback.
Pulling the PLAYL pin HIGH initiates a
playback cycle from the beginning of the
message space. When the device
reaches the EOM marker, it automatically
powers down. If recording has filled the
message space, the entire message is
played. A subsequent rising edge on PLAYL
initiates a new play cycle from the
beginning of the memory.
4.
Level-activated playback (truncated).
If PLAYL is pulled LOW any time during the
playback cycle, the device stops playing
and enters the power-down mode. A
subsequent rising edge on PLAYL initiates a
new play cycle from the beginning of
memory.
5.
Record (interrupting playback).
The REC pin takes precedence over other
operations. Any HIGH-going transition on
REC initiates a new record operation from
the beginning of the memory, regardless of
any current operation in progress.
6.
Record a message, partially filling the
memory.
A record operation need not fill the entire
memory. Releasing the REC pin LOW
before filling the message space causes
the recording to stop and an EOM marker
to be placed. The device powers down
automatically.
7.
Play back a message that partially fills the
memory.
Pulling the PLAYE or PLAYL pin HIGH initiates
a playback cycle. The playback cycle
ceases when the EOM marker is
encountered and the device then powers
down.
8.
RECLED operation.
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
released LOW or when the recording is
completed due to the memory being
filled. This pin also pulses LOW to indicate
the end of a message has been reached.
9.
ROSC Operation
The duration of the device can be varied
by changing the value of R2 (R
OSC
). This
means the ISD1810 device can actually
be between 8 to 16 seconds duration. See
the curve below which charts typical
durations when the R
OSC
is varied from
80 K
to 160 K
.
This feature allows frequency shifting where
a recorded voice or sound can be played
back faster or slower than normal for
special effects. For example, use a 100 K
resistor to make the recording and then
7
ISD1810 Product
ISD
playback with either an 80 K
resistor for faster "chipmunk" talk or with a 120 K
resistor for a slower,
lower voice.
Another feature is a "Pause" or interrupt function that can be done by taking the ROSC resistor to
V
CC
to stop playback momentarily, resuming when the resistor is connected back to ground.
