DESCRIPTION

The IZ8018 is a CMOS multi melody IC. The circuit is composed of a 512-word ROM, address counter, tempo and tone generator,

address control circuit, envelope signal generator, switch control circuit and tone generator. The IZ8018 has complementary

outputs MO, MO for direct piezo drive. Since the IZ8018 includes an envelope circuit on the output MO, it can generate good

melody sound without any external component for envelope circuit. The IZ8018 can easily be connected to Integral’s standard

watch chips and designed especially for this target.
