Addressing
In addition to single-message application, the ISD1100 series provides a full addressing capability for
multiple message application.
The memory array of ISD1100 series has 80 distinct addressable rows, providing the below
resolutions per row. See Application Information for address tables of ISD1100 series.
Looping Capability
The ISD1100 series device has a built-in looping function enabling it to continuously repeat a single
message. This mode is accomplished by taking A3, A6 and A7 pins HIGH simultaneously to
continuously loop from the end of the message to the beginning of the message. Looping is initiated
by a negative transition on PLAYE pin with A3, A6 and A7 held HIGH, then PLAYE is brought back
to HIGH. Looping will continue indefinitely with all three control pins ( PLAYE , PLAYL , REC )
remaining HIGH, until PLAYL is pulsed to LOW, which ends the looping.
