The 8581 and 7862 are two different integrated circuit chips, mainly used in audio and MIDI synthesizers.
8581 chip
The 8581 chip is the standard audio chip in the Commodore 64 video game console and home computers. It has three channels (each capable of producing a different sound), can produce an 8-bit digital signal, and uses Pulse Width Modulation (PWM) technology to produce audio output. The 8581 chip has low power consumption and high reliability, so it is widely used in 8-bit computers and game consoles.
7862 chip
The 7862 chip is a professional MIDI synthesizer chip that is widely used in music workstations and synthesizers. It supports multiple MIDI channels and a variety of timbre, and has a high-quality digital-to-analog conversion (DAC) capability that produces very high-quality audio output. The 7862 chip also has high-speed data transmission and processing capabilities that can simultaneously process multiple audio signals and control signals.
In summary, the 8581 and 7862 are two different integrated circuit chips, mainly used in different audio and MIDI synthesizers. The 8581 chip is suitable for low-power applications such as 8-bit game consoles and home computers, while the 7862 chip is suitable for high-quality audio applications such as professional music workstations and synthesizers.
