Kc89c72 Datasheet 2021 -

The is a versatile CMOS 8-bit microcontroller (MCU) manufactured by brands such as FILFACT and Samsung . Though sometimes categorised broadly as a memory chip due to its internal storage, it functions as a complete control unit equipped with integrated ROM and RAM, making it a staple for reliable data storage and execution in embedded systems. Core Specifications Based on its technical datasheet, the

Q: Can I replace a broken AY-3-8910 with a KC89C72?

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. kc89c72 datasheet
