General Description

The HT2830 is a CMOS LSI chip designed for

use in sound effect products. It is a body struc-

ture including tone circuit, noise circuit, an up-

down counter, and other control logic to

generate various sounds such as JET plane,

motorcycle, helicopter, train, and so forth. Fea-

tures from the customer’s sound samples can be

analyzed and programmed into an internal

ROM by changing a mask layer during device

fabrication. The HT2830 is suitable for various

toy applications.
