Part Number: YM3812
Function: FM Operator TYPE-LII ( OPL II )
Package: 24 Pin DIP or SOP type
The OPLII ( FM OPERATOR type-LII) is an LSI IC which can be used as a sound generation system for computer apparatus,teletext instruments, etc. The OPLII employs frequency modulation for the melody sounds, and has rhythm sounds very close to those of natural musical instruments, marking it possible to synthesize various tones by software control from a CPU.
1. FM sound generation system for realistic sound
2. Built-in vibrato oscillator/amplitude modulation oscillator ( AM )
3. Composite sine wave speech synthesis also possible
4. 5V single power supply
