To set Channel A to middle C (~261 Hz) with a 1 MHz clock:
3 independent analog audio outputs (Channels A, B, C). Noise Generator: 1 internal pseudo-random noise source. Envelope Controls: 1 multi-pattern envelope generator.
| Parameter | Value | | :--- | :--- | | | Programmable Sound Generator (PSG) | | Package | 28-pin DIP (Dual Inline Package) or SOP | | Technology | CMOS (Low power consumption) | | Channels | 3 independent tone channels | | Noise Generator | 1 shared pseudo-random noise source | | Envelope Generator | 1 programmable envelope (can be cycled or single-shot) | | Output | 3-bit D/A converter (digital output, usually via external resistor ladder) | | Clock Frequency | Up to 2 MHz (some clones support up to 4 MHz) | | Supply Voltage (Vdd) | 5V ±10% | | Current Consumption | < 25 mA (typical), < 250 µA (standby) |
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.
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
