Description

The SB82371FB-SZ964 is an electronic component model in the IC Chips product category. It is a multi-function PCI device that combines a PCI-to-ISA bridge function, a PCI IDE function, and a Universal Serial Bus host/hub function. It integrates various common I/O functions found in ISA-based PC systems, such as DMA controller, interrupt controllers, timer/counter, and power management support. The SB82371FB-SZ964 also supports two IDE connectors for up to four IDE devices, providing an interface for IDE hard disks and CD ROMs. It is compatible with motherboard plug and play technology and implements steerable DMA channels and interrupt lines. Additionally, it contains a USB Host Controller that is UHCI compatible and supports an external IOAPIC. The SB82371FB-SZ964 is a high-performance component designed for efficient data transfer and system management.
