Kc89c72 Datasheet Verified (2025)
2.7V to 5.5V DC, making it highly adaptable for both battery-operated 3.3V systems and legacy 5V industrial environments.
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 KC89C72 is a microcontroller unit (MCU) developed by Sanyo (now part of ON Semiconductor), which has been widely used in various electronic applications due to its reliability, flexibility, and cost-effectiveness. In this article, we will provide an in-depth analysis of the KC89C72 datasheet, covering its features, specifications, and typical applications.
Housed in a standardized DIP-40 layout, the pinout aligns directly with original retro system configurations. Interfacing requires setting up the parallel data bus and configuring precise bus control states. Critical Bus Control Sinking
: It remains in production for use in modern slot machines , where its robust sound generation capabilities are still utilized. For detailed implementation and Arduino projects, you can
Supports full-duplex asynchronous serial communication, essential for debugging via PC serial terminals or interfacing with Bluetooth/Wi-Fi modules.
Based on sourcing sites and user reports, the KC89C72 is most commonly encountered in a plastic body, featuring 40 pins with 0.6-inch row spacing. This packaging makes it breadboard-friendly and suitable for prototyping. A PLCC (Plastic Leaded Chip Carrier) variant also exists for surface-mount applications.
However, this does not mean the chip is unusable. Because the KC89C72 is a clone of the AY-3-8910,
