Kc89c72 Datasheet

Flexible routing allowing tone, noise, or combined outputs per channel.

The KC89C72 reads registers using three primary steering pins: , Bus Clock 2 (BC2) , and Bus Direction (BDIR) . Microcontrollers write to the sound generator by modulating these pins into three distinct phases: Latch Address (

: It shares the exact same pinout as the AY-3-8910 , making it ideal for hardware restorations or building compatible sound cards like the Covox Sound Master . kc89c72 datasheet

The KC89C72 is an 8-bit CMOS microcontroller that belongs to the 89C series of MCUs. It is built around a high-performance CPU core with a maximum operating frequency of 16 MHz. The device is fabricated using a high-density CMOS process, which enables it to achieve low power consumption and high reliability.

The original , released by General Instrument in 1978, was a revolutionary chip that defined the sound capabilities of a generation of home computers, including the MSX, ZX Spectrum, and Amstrad CPC systems, as well as numerous arcade games.

The KC89C72 is well-documented in the hobbyist community for use with platforms like Arduino. An called "KC89C72 driver for Arduino with '595" is available on GitHub, providing a ready-to-use implementation that includes a schematic for breadboard prototyping. This driver addresses potential audio distortion issues when mixing the three output channels by recommending a 1kΩ resistor to ground at the mixed output to prevent channel crosstalk and clipping. The KC89C72 is an 8-bit CMOS microcontroller that

The KC89C72 uses three control pins – – to select read/write operations and address/data latches.
