HSMC Product Specification

H66T19/32/68 Series

Description

The H66T19/32/68 series is a CMOS LSI designed for use in door bell,

telephone and toy applications. It is an on-chip ROM program-med for

music performance. Produced by COMS technology, the device results in

very low power consumption. Since the H66T19/32-/68 series includes

oscillation circuits, a compact melody module can be constructed with only

a few additional components.

Feature

• 64-Note ROM memory

• 1.5V to 3V power supply and low power consumption

• Dynamic speaker can be driven with external NPN transistor

• OSC resistor is built-in

• Built-in level hold mode

• Power on reset: melody begins from the first note
