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

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

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.
