The ISD1616 IC delivers record/playback length from 10.6 seconds to 32 seconds. Playback ceases once the signal reverts to HIGH Time-frame PLAYL pin of the IC picks up a LOW going potenial and continues to be at LOW. Level-trigger Playback: A playback functioning commences whenever switch (SW3) PLAYL is activated and playback halts whenever switch is released. How to Play the recorded messageĮdge-trigger Playback: A playback functioning begins as soon as switch (SW2) PLAYE is clicked or PLAYE pin of IC finds a LOW going potential going above the selected debounced period The REC pin comes with an internal pull-up feature. In case REC is drawn LOW within a playback cycle, the playback right away puts a stop to and recording begins right from the start of the memory. REC normally takes priority over any playback functions. Therefore, the unit automatically makes its way into into standby setting. After that an End-of-Message (EOM) marker is composed at the finish of message, which allows a succeeding Playback cycle to generate effectively. A record cycle is carried out when REC is drawn to HIGH or complete memory is loaded up. The unit begins recording right from the start from the memory as soon as REC transits through HIGH to LOW and continues at LOW. Recording ceases as soon as the recording button removed or the signal on ICs pin comes back to HIGH. The unit starts off recording anytime REC switch is pressed or recording pin of IC drawn HIGH to LOW and continues at LOW. CN2 (AUD) is current drive output for connecting the circuit with additional audio amplifier. Hook up the 8 ohms 0.5W speaker to LS1 (SPK), implement 5V DC to CN1, and ensure polarity is proper or else it could destroy the IC. Number of Record cycles is around 1 lac times.Approximate massage retention time is 100 years.Low Noise excellent quality voice record/playback.
