Includes two 8-bit parallel I/O ports, often used for interfacing with joysticks or other peripherals. Microprocessor Interface:

: Includes two 8-bit parallel I/O ports for interfacing with other components.

: Includes two general-purpose 8-bit parallel I/O ports, consistent with the original AY-3-8910 pinout.

Available in a DIP-40 (Dual In-line Package with 40 pins), which is ideal for through-hole mounting on printed circuit boards (PCBs) and prototyping.

| 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) |
