UNISONIC TECHNOLOGIES CO., LTD UM66TXXL CMOS IC 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. 1TO-92 FEATURES *-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 *Pb-free plating product number: UM66TxxLK ORDERING INFORMATION Order Number Pin Assignment Package Packing Normal Lead Free Plating 1 2 3 UM66TxxL-T92-B UM66TxxLK-T92-B TO-92 VSSVDDO/P Tape Box UM66TxxL-T92-K UM66TxxLK-T92-K TO-92 VSSVDDO/P Bulk UM66TxxL-T92-R UM66TxxLK-T92-R TO-92 VSSVDDO/P Tape Reel UM66TxxLK-T92-B(1)Packing Type(2)Package Type(3)Lead Plating(4)Song Series(1) B: Tape Box, K: Bulk, R: Tape Reel(2) T92: TO-92(3) K: Lead Free Plating, Blank: Pb/Sn(4) xx: refer to SONG SERIES LIST SONG SERIES LIST P/N SONG NAME UTC UM66T05L Home Sweet Home UTC UM66T08L Happy Birthday UTC UM66T11L Love Me Tender UTC UM66T19L For Alice UTC UM66T32L COO COO waltz www.unisonic.com.tw 1 of 4 Copyright © 2005 Unisonic Technologies Co., Ltd QW-R502-042,F 元器件交易网www.cecb2b.com

UM66TXXL CMOS IC 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 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 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, 320,480,0,960,1920 J/minute. www.unisonic.com.tw UNISONIC TECHNOLOGIES CO., LTD 3 of 4 QW-R502-042,F 元器件交易网www.cecb2b.com
