Applications Note
Some users may experience an unexpected recording taking place when their circuit is powered up,
or the batteries are changed and VCC rises faster than REC . This undesired recording prevents
playback of the previously recorded message. A spurious End Of Message (EOM) marker appears at
the very beginning of the memory, preventing access to the original message, and nothing is played.
To prevent this occurrence, place a capacitor (approx. 0.001 F) between the control pin ( REC ) and
VCC. This pulls the control pin voltage up with VCC as it rises. Once the voltage is HIGH, the pull-up
device will keep the pin HIGH until intentionally pulled LOW, preventing the false EOM marker.
Since this anomaly depends on factors such as the capacitance of the user’s printed circuit board, not
all circuit designs will exhibit the spurious marker. However, it is recommended that the capacitor is
included for design reliability. A more detailed explanation and resolution of this occurrence is
described in Application Information.
