Description
The AY-3-8910/8912/8913 Programmable Sound Generator (PSG) is a LSI Circuit which can produce a wide variety Of complex sounds under software control. The AY-3-8910/ 8912/8913 is manufactured in the General Instrument N-Channel lon Implant Process. Operation requires a single +5V power supply, a TTL compatible clock, and a microprocessor 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 bmakes it useful in applications such as music synthesis, sound effects 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 to continue its other tasks, the PSG can continue to produce sound after the initial commands have been given by the control processor. The fact that realistic sound production often involves more than one effect is satisfied by the three independently controllable channels available in the PSG.
AlI of the circuit control signals are digital in nature and intended to be provided directly by a microprocessor/microcomputer. This means that one PSG can produce the full range of required sounds with no change in external circuitry. Since the frequency response of the PSG ranges from sub-audible at its lowest frequency to post-audible at its highest frequency, there are few sounds which are beyond reproduction with only the simplest electrical connections.
Since most applications of a microprocessor/PSG system would also require interfacing between the outside world and the microprocessor. this facility has been designed into the PSG. The AY-3- 8910 has two 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 has no ports and 24 leads.
