General Description
The HT8656 is a single chip CMOS LSI for
talking back applications using an ADM algo-
rithm. Functions of the IC consist of record-
ing/playing as well as auto power off. It starts
recording when a sound input is detected, and
stops to play back when silence lasts 0.5 sec-
onds during recording. The auto power off func-
tion is activated once a REC/PLAY cycle has
been implemented 64 times or an interval of
silence exceeds 2 minutes.
The HT8656 provides a recording capacity of 2
seconds for DRAM of 64K and 8 seconds for
DRAM of 256K at a 32Kb sampling rate and
double recording capacity at a 16K b sampling
rate. A higher sampling rate will result in
sounds of better quality but sacrifice the record-
ing time, and vice versa.
