Recording starts whenever a sound input is
detected. It then stops once a 0.5 seconds si-
lence is detected or the recording capacity is
full. After that, talking back comes into play.
Play function
The HT8656 stops to play back the recorded
sounds when an interval of silence lasts 0.5
seconds during recording. Its sampling rate is
the same as the rate of recording sounds.
Power control
The HT8656 provides a START pin for power
control. The START pin is of high impedance
and switch Q is turned off initially. After the
START pin is triggered, it will remain at a low
level and switch Q is turned on. The START pin
is of high impedance and the chip’s power is
switched off when a REC/PLAY cycle has been
implemented 64 times or an interval of silence
lasts over 2 minutes.
Motor
The HT8656 provides a motor driving pin. The
motor is turned on during playing but off once
talking back is terminated.
LED
The LE D pin displays the status of the HT8656.
LE D is switched ON when the IC is in the
standby state. Its intensity varies inversely
with the sound volume when the IC is in the
recording state. In the playing state, the LE D is
switched OFF.
