ISD1400 SERIES
Publication Release Date: November 16, 2005

Revision 1.3
Addressing
In addition to providing single message application, the ISD1400 series provide a full addressing
capability.
The ISD1400 series have 160 distinct addressable segments, providing the below resolutions. See
Application Information for ISD1400 address tables.

6.2. OPERATIONAL MODES
The ISD1400 series have several built-in operational modes providing maximum functionality with a
minimal additional components. The operational modes use the address pins, but are mapped to
outside the normal address range. When the two Most Significant Bits (MSBs), A6 and A7, 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. Firstly, all operations begin
initially at address 0, which is the beginning address. 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 but not from playback to record when A4 is HIGH
in Operational Mode.
Secondly, an Operational Mode is executed when any of the control inputs, PLAYE , PLAYL or
REC
, goes LOW and the two MSBs are HIGH. This Operational Mode remains in effect until the next
LOW-going control input signal, at which point the current address/mode levels are sampled and
executed.
6.2.1. 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.
A0 – Message Cueing
Message Cueing allows the user to skip through messages, without knowing the actual physical
addresses of each message. Each LOW pulse causes the internal address pointer to skip to the next
message. This mode is used for playback only and typically used with the A4 Operational Mode.
