Kc89c72 Datasheet Repack Jun 2026

Internally, the chip contains three tone channels, a noise generator, mixers, a programmable envelope generator, and three digital-to-analog converters (DACs) to produce the final analog signals. The tone frequency ( f ) for a channel is calculated by the formula f = (Clock Frequency / 16) / Tone Period Value .

is a CMOS 3-channel Programmable Sound Generator (PSG) manufactured by Korea Electronics Co. (KEC) . It serves as a 100% software- and pin-compatible clone of the iconic and Yamaha YM2149 sound chips. By implementing a modern CMOS architecture, the
