Intel 82091AA
The Intel 82091AA is an Advanced Integrated Peripheral (AIP) chip for EISA/ISA systems, integrating multiple I/O controllers.
The Intel 82091AA is an Advanced Integrated Peripheral (AIP) chip designed for EISA and ISA bus systems. It integrates a floppy disk controller, two UARTs (serial ports), a parallel port, an IDE controller, and an oscillator into a single package. This chip consolidates common I/O functions, reducing component count and board space in motherboards and expansion cards. It is typically used in conjunction with Intel's EISA/ISA chipset solutions to provide complete system I/O capabilities.
