15600中文资料MELODY IC数据手册UTC规格书

描述 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 opti on) of the RC oscillation circuit is builted in. Moreover, a small-sized package can be suitable for space –saving applications.
