UTC UM66TXXL
MELODY INTEGRATED
CIRCUIT
DESCRIPTION
The UTC UM66TXXL 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 UM66TXXL series
include oscillation circuits a compact melody module
can be constructed with only a few additional
components.
FEATURES
*64-Note Rom memory
*1.5V ~ 4.5V power supply and low power
consumption
*Dynamic speaker can be driven with external NPN
transistor
*OSC resistor hold mode
*Power on reset: melody begins from the first note
*Built in level hold mode
