HSMC Product Specification
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
