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
encountered and the device then powers
down.
EOM
marker
is
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
