Mode described later in the Operational Mode
section.
Chip Enable Input (CE)
The CE pin is taken LOW to enable all Playback
and Record operations. The address inputs and
Playback/Record input (P/R) are latched by the
falling edge of CE. CE has additional functionality
in the M6 (Push-Button) Operational Mode
described later in the Operational Mode section.
Playback/Record Input (P/R)
The P/R input is latched by the falling edge of the
CE pin. A HIGH level selects a Playback cycle
while a LOW level selects a Record cycle. For a
Record cycle, the address inputs provide the start-
ing address and recording continues until PD or
CE is pulled HIGH or an overflow is detected (i.e.
the chip is full). When a Record cycle is terminated
by pulling PD or CE HIGH, an End-Of-Message
(EOM) marker is stored at the current address in
memory. For a Playback cycle, the address inputs
provide the starting address and the device will
play until an EOM marker is encountered. The
device can continue past an EOM marker in an
operational mode, or if CE is held LOW in address
mode. (See page 1-85 for more Operational
Modes).
End-Of-Message / RUN Output (EOM)
A nonvolatile marker is automatically inserted at
the end of each recorded message. It remains
there until the message is recorded over. The
EOM output pulses LOW for a period of T
the end of each message.
EOM
at
In addition, the ISD2500 Series has an internal
V
CC
detect circuit to maintain message integrity
should V
CC
fall below 3.5V. In this case, EOM
goes LOW and the device is fixed in Playback-only
mode.
When the device is configured in Operational
Mode M6 (Push-Button Mode), this pin provides an
active-HIGH RUN signal, indicating the device is
currently recording or playing. This signal can con-
veniently drive an LED for a visual indicator of a
Record or Playback operation in process.
Overflow Output (OVF)
This signal pulses LOW at the end of memory
space, indicating the device has been filled and the
message has overflowed. The OVF output then fol-
lows the CE input until a PD pulse has reset the
device. This pin can be used to cascade several
ISD2500 devices together to increase Record/
Playback durations.
