Description
Features:
- VCC-3.3V power supply
- GND: Power ground
- REC: 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 the playback (PLAYL or PLAYE) signal.
- Playback, Edge-Activated: When a HIGH-going transition is detected, playback continues until an End-of-Message (EOM) marker is encountered or the end of the memory space is reached.
- PLAYL: Playback, Level activated. When this input pin level transits from LOW to HIGH, a playback cycle is initiated.
- Speaker Outputs: The SP+ and SP pins provide direct drive for loudspeakers with impedances as low as 8.
- MIC (microphone input): the microphone input transfers its signals to the on-chip preamplifier.
- FT (feed through): This mode enables the Microphone to drive the speaker directly.
- PE: Play the records endlessly
