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.
