UTC UM66TXXL LINEAR INTEGRATED CIRCUIT 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. 1 TO-92 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 1: VSS 2: VDD 3: O/P(Melody output) ORDERING INFORMATION UTC UM66T X X L LEVEL HOLD Mode Song series SONG SERIES LIST UTC P/N SONG NAME UTC UM66T05L UTC UM66T19L UTC UM66T32L Home sweet home For Alice COO COO waltz UNISONIC TECHNOLOGIES CO., LTD. 1 QW-R501-001,B UTC UM66TXXL LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS PARAMETER (Operating temperature range applies unless otherwise specified.)

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.
