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

APPLICATIONS
The Marvell 88SE9220 and 88SE9230 SATA host controllers are ideal solutions for RAID on motherboard (ROMB) and
cost-effective host bus adapters (HBAs). It allows PCIe-based host systems to control up to four SATA 6Gb/s HDDs or
SSDs. An embedded ARM-based CPU makes this product a pure hardware RAID controller and enables in-box driver
support without additional driver installation. The included Marvell Storage Utility (MSU) provides a user-friendly
interface to end users, while the Marvell RAID driver allows the drives to be used with a SATA port multiplier for
increased system performance and capacity.
The Marvell HyperDuo offers a breakthrough embedded technology for new generation 6Gb/s SATA Controllers,
enabled on the Marvell 88SE9230 and 88SE9220. Based on years of research and patent-pending software and
hardware, HyperDuo enables 80 percent of the performance of an SSD at less than half the cost. Configured with
one hard drive and multiple SSDs, HyperDuo uses intelligent algorithms to automatically migrate hot data to the
SSD while enabling all data to be safely stored on a larger capacity SATA HDD for higher input/output operations per
second (IOPS), throughput and capacity.
The Marvell 88SE9235 can be used for embedded platform applications such as home NAS/media servers, DVR/NVR
and set-top boxes, or by HBA vendors to develop their own RAID software or in-box OS drivers.
Fully programmable on-chip transceivers support SATA, eSATA, and xSATA at 6 Gb/s and are backward compatible
to 1.5 Gb/s and 3 Gb/s. Built-in support for SATA Port Multipliers with FIS-based switching ensures maximum
performance. The small footprint of the device, and the few required external components, take up minimal board
space, easing system design and reducing cost. Embedded enclosure management via I2C protocol, further reduces
system cost.
