DESCRIPTION

The AY-3-8910/8912/8913 Programmable Sound Generator ( PSG ) isaLSICircuit which can produce a wide variety of complexsounds under software control. The AY-3-8910 / 8912 / 8913 is manufactured inthe General Instrument N-channel lon Implant Process. Operation requires a single + 5V power supply, a TTL compatible clock, and amicroprocessor controller such as the General Instrument 16-bit CP1610 or one of the PIC1650 series of 8-bit microcomputers.

The PSG is easily interfaced to any bus oriented system. Its flexibility makes it useful in applications such as music synthesis, soundeffects generation, audible alarms, tone signalling and FSK modems. The analog sound outputs can each provide 4 bits of logarithmic digital to analog conversion, greatly enhancing the dynamic range of the sounds produced.

In order to perform sound effects while allowing the processor tocontinue its other tasks . the PSG can continue to produce soundafter the initial commands have been given by the control processor. The fact that realistic sound production often involves more than oneeffect is satisfied by the three independently controllable channelsavailable in the PSG.

All of the circuit control signals are digital in nature and intended tobe provided directly by a microprocessor/microcomputer. This means thatonePSG can produce the full range of required soundswith no change in external circuitry. Since the frequency response ofthe PSG ranges from sub-audible at its lowest frequency to post-audible at its highest frequency, there are few sounds whichare beyond reproduction with only the simplest electrical connections.

Since most applications of a microprocessor / PSG system would alsorequire interfacing between the outside world and the microprocessor , this facility has been designed into the PSG. The AY-3-8910 hastwo general purpose 8-bit I/O ports and is supplied in a 40 lead package : the AY-3-8912 has one port and 28 leads : the AY-3-8913 hasno ports and 24 leads.
