ISD1820 Recording Module Voice Board With On Board Mic and Loud Speaker

ISD1820 is a small Voice Recorder and Playback module that can do the multi-segment recording. The user can achieve a high quality of recording (for 8 to 20secs) for each application with the adjustment of the on-board resistor. This Voice Recorder/Playback module is designed with embedded-Flash memory, which can hold data for up to 100 years and erase/record the life cycle up to 100,000. Pin Description of ISD1820 Recorder/Playback Module Pin Name: Description VCC: DC 2.4-5.5V GND: Ground FT: FeedThrough: This mode enables the Microphone to drive the speaker directly. REC/REC (Button): The REC input is an active‐HIGH record signal. The module starts recording whenever REC is HIGH. This pin must remain HIGH for the duration of the recording. REC takes precedence over either playback (PLAYL or PLAYE) signal. P-E/PLAY-E (Button): Playback, Edge‐activated: When a HIGH‐going transition is detected continues until an End‐of‐Message (EOM) marker is encountered or the end of the memory space is reached. P-L/PLAY-L (Button): Playback, Level‐activated, when this input pin level transits for LOW to HIGH, a playback cycle is initiated. SPI: The SP+ and SP‐ pins provide a direct drive for loudspeakers with impedances as low as 8Ω. Note: This is not Serial Parallel Interface Pins. MIC: Microphone In: the microphone input transfers its signals to the on‐chip pre-amplifier.
