UNISONIC TECHNOLOGIES CO., LTD UM68TXX Preliminary CMOS IC 128 NOTES DUAL TONE MELODY GENERATOR PWM OUTPUT DIRECT TO BUZZER AND SPEAKER DESCRIPTION 1 The UTC UM68TXX 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 UM68TXX series include oscillation circuits a compact melody module can be constructed with only a few additional components. FEATURES * 128-Note Rom memory * 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 * 27 notes (including rest) available Package TO-92 TO-92 Pin Assignment 1 2 3 VSS VDD O/P VSS VDD O/P Packing Tape Box Bulk SONG SERIES LIST P/N UTC UM68T05 UTC UM68T08 UTC UM68T19 * OSC resistor hold mode * Power on reset: melody begins from the first note * Built in level hold mode * PWM output ORDERING INFORMATION Order Number Lead Free Halogen Free UM68TxxL-T92-B UM68TxxG-T92-B UM68TxxL-T92-K UM68TxxG-T92-K TO-92 SONG NAME Sweet Home Happy Birthday For Alice MARKING www.unisonic.com.tw Copyright © 2014 Unisonic Technologies Co., LTD 1 of 3 QW-R502-924.b UM68TXX Preliminary CMOS IC ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL RATINGS UNIT DC Supply Voltage VCC 0V~5V V Input/output Voltage VIN/VOUT GND-0.2V~VDD +0.2V V Junction Temperature TJ 125 °C Operating Temperature TOPR -20~+85 °C Storage Temperature TSTG -40~+150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
