Preliminary

CMOS IC

128 NOTES DUAL TONE

MELODY GENERATOR PWM

OUTPUT DIRECT TO BUZZER

AND SPEAKER



DESCRIPTION

The UTC UM68TXX series are CMOS LSI designed for

TO-92

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.



FEATURES

* 128-Note Rom memory

* OSC resistor hold mode

* 2.5V ~ 5V power supply and low power consumption

* Dynamic speaker can be driven with external NPN transistor

* 14 tempos available through mask setting

* 15 beats available

* Power on reset: melody begins from the first

note

* Built in level hold mode

* PWM output

* 27 notes (including rest) available
