HT2860 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 simultaneously triggering more than one key according 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 suitable for various toy applications.
