16 harmonies tone generator LSI for cellular phone
BU8772KN
Description
BU8772KN is a tone generator LSI for cellular phones.
This LSI generates 16 harmonies simultaneously.
A total of 206 sounds (128 sounds + 46 drum set +
32 effect sounds) can be generated.
FIFO and Seaquencer for playing are incorporated.
The seaquencer itself can control the performance time
and play the music by sending the melody data to FIFO.
