Marvell 88SE9220/9230/9235
PCIe to SATA 6Gb/s Controllers
PRODUCT OVERVIEW
Marvell, a market leader of PCIe to SATA embedded controller devices, has added the Marvell^® 88SE9220 and Marvell
88SE9230 host controllers as cost-effective solutions for connecting Serial ATA (SATA) peripherals. The Marvell
88SE9220 and 88SE9230 connect SATA III devices to a PCI Express (PCIe) 2.0 host, delivering up to 1 Gigabyte-
per-second (GB/s) bandwidth. Each host controller supports two or four 6 gigabit-per-second (Gb/s) SATA peripheral
interface ports and a two-lane 5.0 Gb/s PCIe host interface. In addition, it features hardware RAID running with
an enhanced ARM-based processor to offload the host CPU; Marvell proprietary Marvell HyperDuo technology for
automated solid-state drive (SSD)/hard disk drive(HDD) tiering; on-the-fly AES 128/256-bit encryption for connected
SATA SSD/HDD devices; and AHCI interface for in-box driver support. A complete suite of RAID 0/1/10 and HyperDuo
software is provided, including the OS device driver, BIOS/Firmware and management utility. The Marvell 88ES9220
and 88SE9230 host controllers allow for a small footprint, highly integrated SATA III design that will enable high-
performing yet cost-effective HDD, SSD and other peripheral designs
