PIN NO.

PIN NAME

FUNCTION

SOIC/ TSOP

PDIP

ANA OUT

Analog Output: This pin provides the preamplifier output to the

user. The voltage gain of the preamplifier is determined by the

voltage level at the AGC pin.

Overflow: This signal pulses LOW at the end of memory array,

OVF

indicating the device has been filled and the message has

overflowed. The OVF output then follows 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.

Chip Enable: The CE input pin is taken LOW to enable all

playback and record operations. The address pins and

playback/record pin (P/R ) are latched by the falling edge of CE.

CE has additional functionality in the M6 (Push-Button)

Operational Mode as described in the Operational Mode section.

Power Down: When neither record nor playback operation, the PD

pin should be pulled HIGH to place the part in standby mode (see

I_SBspecification). When overflow ( OVF ) pulses LOW for an

overflow condition, PD should be brought HIGH to reset the

address pointer back to the beginning of the memory array. The PD

pin has additional functionality in the M6 (Push-Button) Operation

Mode as described in the Operational Mode section.

End-Of-Message: A nonvolatile marker is automatically inserted at

EOM

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_EOMat the end of each message.

In addition, the ISD2500 series has an internal V_CCdetect circuit to

maintain message integrity should V_CCfall 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 signal, indicating

the device is currently recording or playing. This signal can

conveniently drive an LED for visual indicator of a record or

playback operation in process.
