Intel 82091AA
The Intel 82091AA is an Advanced Integrated Peripheral (AIP) chip for EISA/ISA systems.
The Intel 82091AA is an Advanced Integrated Peripheral (AIP) designed for EISA/ISA bus systems. It integrates multiple I/O functions into a single chip, including a floppy disk controller, two UARTs (serial ports), a parallel port, an IDE controller, and an oscillator. This chip reduces the number of discrete components needed on a motherboard, simplifying design and improving reliability. It is used in conjunction with EISA/ISA chipsets and processors from the same era.
