= M66 rf SIMPLE wi MELODY GENERATOR
DESCRIPTION
The M66 series are low power CMOS LSI in TO-92 package, designed for the application of melody generation. The built in oscillator and strong driving capability minimise the external components required. A maximum of 128 notes can be programmed and repeat mode. It is suitable for use in melody cards, toys and other similar applications. PIN ASSIGNMENT (T'O-92)
