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 μA, 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.
