ISD1400 SERIES
Publication Release Date: November 16, 2005

Revision 1.3
Functional Description Example
The following operating examples demonstrate the functionality of the ISD1400 series.
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.
