Kc89c72 Datasheet Jun 2026

The next time you come across a dusty PDF titled "KC89C72 Datasheet," do not scroll past it. Open it. Look at the block diagram, the timing waveforms, the tiny Cyrillic annotations. You are holding a document that is at once a technical manual, a spy novel, and a eulogy. It is proof that even in the most rigid, formulaic genre of technical writing—the datasheet—there exists the potential for drama, ingenuity, and survival. In the end, a chip is just silicon. But its datasheet? That is its soul.

To set Channel A to middle C (~261 Hz) with a 1 MHz clock: kc89c72 datasheet

The Samsung/Filfact KC89C72 is a legacy SSI memory chip packaged in a DIP-40 form factor, designed for through-hole mounting in embedded systems and industrial applications. It provides robust, reliable functionality for older architectures, though it serves primarily as an in-stock replacement part rather than a component for new, modern designs.

The internal register architecture, as detailed in the KC89C72 datasheet, is identical to the AY-3-891x family. There are (R0–R15). You are holding a document that is at

The is a 3-voice programmable sound generator (PSG) IC. It was manufactured by Microchip Technology (after acquiring GI’s semiconductor division) and also under license by other vendors like GoldStar (now LG) and UMC .

On the KC89C72, pins 25 and 26 (/IOA, /IOB) are not functional as general-purpose I/O (unlike the AY-3-8910). Pull them to Vdd through 10k resistors.
