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.

FUNCTIONAL DESCRIPTION
OSCILLATOR CIRCUIT
The oscillator frequency is used as a time for tone and beat generators. Its accuracy affects the quality of the
music.
TONE GENERATOR
Tone Frequencies are oscillator frequencies-M, where m is any even number from 64 to 256. Within a melody 14C
scales can be selected including Pause code and End code. The tone generator is a programmed divider, The
Range of Scales is from “C4” to “C6” and range of frequency varies from 258Hz to 23768Hz.
RHYTHM GENERATOR
The rhythm generator is also programmed dividers. It contain 15 available rhythms as
follows:1/4,1/2,3/4,1,1-1/4,1-1/2,1-/3/4,2,2-1/4,2-1/2,2-/3/4,3,3-1/4,3-1/2,3-/3/4.Four rhythms can be selected from
these.
MELODY ROM
The Mask Rom can memorize 64 notes with 6 bit.4 bits are used for controlling the scale code and 2 bits are
used for controlling the rhythm code.
TEMPO GENERATOR
There are 15 available tempos in the UTC UM66T series. The 15 tempos are:128,137,148,160,175,192,213,
240 , 274, 320,480,640,960,1920 J/minute.
