General Description

The HT2860 is a CMOS LSI chip designed for

use in sound effect products. It can generate six

sections of programmable sounds. The LSI is

equipped with tone circuit and control logic to

generate various sounds including door bell,

alarm, melodies, etc. Users can play not only

sound sections (S1~S6) by triggering a single

key (K1~K6), but serial sound sections by si-

multaneously triggering more than one key ac-

cording to the key priority where K1 is the

highest and K6 is the lowest. The customer ’s

sound sample is analyzed and programmed into

an internal ROM by changing a mask layer

during device fabrication. The HT2860 is suit-

able for various toy applications.
