15600 - MELODY-IC

Description

UTC 15600 Series is a CMOS IC circuits which contain a programmed mask ROM to generate chord music.

The capacity of the ROM being used for storage of such music information is of 128 words and up to two numbers of music melodies under two different sound sources can be optioned for storage into it.

Features

  • S.
  • Range of operating voltage: 0.9~5.5V.
  • Reference signal source frequency: 32.768KHZ,47.520KHZ(mask option selection).
  • Options : 1. changing the melody midway during performance: Possible or not possible (mask option selection) 2. selection of the reference sound frequency: when selecting the signal source frequency of 32.768kHz, A4=440Hz(standard) or C4=256Hz when selecting the signal source frequency of 47.520kHz: A4=440Hz 3. Selection of performance sound range: when selectin.

UNISONIC TECHNOLOGIES CO., LTD 15600 MELODY IC CMOS IC  DESCRIPTION UTC 15600 Series is a CMOS IC circuits which contain a programmed mask ROM to generate chord music. The capacity of the ROM being used for storage of such music information is of 128 words and up to two numbers of music melodies under two different sound sources can be optioned for storage into it. Also, the total integration (for mask option) of the RC oscillation circuit is builted in. Moreover, a small-sized package can be suitable for space –saving applications.  FEATURES * Range of operating voltage: 0.9~5.5V * Reference signal source frequency: 32.768KHZ,47.520KHZ(mask option selection) * Options : 1. changing the melody midway during performance: Possible or not possible (mask option selection) 2.
