Kc89c72 Datasheet Jun 2026

Channel A, B, and C analog outputs. Typical Applications

The is a widely recognized electronic component primarily known as a 100% software-compatible clone of the classic General Instrument AY-3-8910 Programmable Sound Generator (PSG) . Manufactured by File in Taiwan, this integrated circuit (IC) has historically played a crucial role in the retro-computing and arcade gaming industries. Technical Specifications kc89c72 datasheet

A: Yes, in most cases. Both have identical pinouts and register sets. However, check the analog output impedance – the KC89C72 may require different external resistor values. Channel A, B, and C analog outputs

The KC89C72 is a ghost in the datasheet library—a functional component with a missing identity. If you are repairing a vintage Korean arcade board or a obscure 80s home computer, do not despair. Treat the KC89C72 , download that original datasheet, and you will have all the electrical and programming information required to get sound out of the chip. Technical Specifications A: Yes, in most cases

Prices are highly variable. In one Chinese source, the chip is listed at around (approx. $0.80 USD), and in some cases, shipping is included . More commonly, specialized distributors require purchase of larger quantities or include higher per-unit pricing. For small quantities, eBay or individual sellers on Taobao may be the most accessible options. Some users also salvage KC89C72 chips from scrap slot machine and arcade game boards .

The KC89C72 is an integrated circuit manufactured by (sometimes written as Jile or File brand) that serves as a direct, pin-compatible clone of the legendary General Instrument AY-3-8910 Programmable Sound Generator (PSG) . While the original AY-3-8910 has long been discontinued, the KC89C72 remains available through specialty suppliers and is actively used by retro computing enthusiasts, hobbyists, and those maintaining legacy industrial equipment.
