 DESCRIPTION
1
The UTC UM68TXX series are CMOS LSI designed for
using in door bell, telephone and toy application. It is an on-chip
ROM programmed for musical performance. Produced by
CMOS technology, the device results in very low power
consumption. Since the UTC UM68TXX series include
oscillation circuits a compact melody module can be constructed
with only a few additional components.
