2-Serial/1-Parallel ATA Host Controller

Product Overview

The M5283 provides personal computer systems with PCI/Cardbus device solution of the highest integration: It includes two Serial-ATA Host controllers for supporting 2 ports, compliant with Serial ATA 1.0 specifications, one fully Parallel-ATA Host controller for supporting single channel and a Flash ROM controller.

The M5283 provides PCI interface up to 33MHz. It is PCI specification 2.2 compliant. Through high integration of the M5283, board manufacturers can build a cost-effective products that provides high-performance SATA and PATA features.
