2. General Description
The IT8888G is a PCI to ISA bridge single function device. The IT8888G serves as a bridge between the PCI bus
and ISA bus. The IT8888G’s 32-bit PCI bus interface is compliant with PCI Specification V2.1 and supports both
PCI Bus Master & Slave. The PCI interface supports both programmable positive and full subtractive decoding
schemes.
The IT8888G also integrates two enhanced DMA Slave controllers for achieving PCI DMA cycles: PC/PCI DMA
Slave Controller & Distributed DMA Slave Controllers.
The IT8888G also implements the optional fast positive decode of F, E, D, C memory segments. This special
feature can provide a direct connection to an FALSH boot ROM.
The NOGO function, which is also implemented in the IT8888G for enabling or disabling subtractive decode of PCI
interface, could be a software controlled output pin from other host controlled devices. The Serial IRQ is also
implemented in the device for sending and receiving ISA IRQs & IOCHCK#. The device includes an ISA interface
which supports full ISA compatible functions.
The IT8888G is available in 160-pin TFBGA package.
