) separately, tying them together at a single point (star ground) near the power supply input to avoid digital switching noise corrupting analog sensor readings.
Advanced 8-bit RISC or enhanced 8051-based core (depending on the specific manufacturer variant).
The internal oscillator is completely stopped. All registers and SRAM contents are retained, and power consumption drops to its absolute minimum (often in the microampere range). The chip can only be awakened via an external hardware reset or a designated external interrupt. 5. Hardware Layout and Design Best Practices kc89c72 datasheet

As a direct clone of the AY-3-8910, the KC89C72 shares its identical 40-pin layout, making it a "drop-in" replacement in most circuits. Key interface signals include:
Input and output pins for the internal inverting amplifier. These connect to an external quartz crystal or ceramic resonator.
