Winbond Electronics Corporation W83C553F
The W83C553F Enhanced System I/O (SIO) Controller with PCI Arbiter is a highly integrated device intended for use in any Peripheral Component Interconnect (PCI) system, supporting x86 or PowerPC (non-x86) type microprocessors. It supports all PCI 2.1 compliant CPU bridge implementations and directly interfaces with PCI and ISA industry standard buses, including two direct drive IDE channels supporting up to four peripherals. The W83C553F is a universal PCI device which can be used with many CPU-to-PCI bridge solution.| Part No. | W83C553F |
