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 16Kb sampling

rate. A higher sampling rate will result in

sounds of better quality but sacrifice the record-

ing time, and vice versa.
