„ Two PCI Express interfaces (x4)
• PCI Express Base 1.1 compliant
• Integrated low-power SERDES PHY, based on
proven Marvell SERDES technology
• Can be configured as an Endpoint or as Root
Complex

„ Configurable PCI Express x4 or Quad x1 port
• Each one of the PCI Express ports can be
configured to act as four independent x1 ports; this
is useful for interfacing multiple off-the-shelf
PCI-Express devices.
• Each of the x1 ports is PCI Express Base 1.1
compliant, has its own register file, and supports
the full feature set as the x4 port.
„ PCI Express Master specific features

• Maximum read request of up to 128 bytes
• Maximum write request of up to 128 bytes
„ PCI Express Target specific features
• Supports reception of up to four read requests
• Maximum read request of up to 4 KB
• Maximum write request of up to 128 bytes
• Supports PCI Express access to all of the device’s
internal registers
„ Two Gigabit Ethernet MACs
• Support 10/100/1000 Mbps
• Full wire speed receive and transmit of short
packets
• GMII/MII interface when using a single port
• RGMII interface when using dual ports
• Priority queueing on receive based on DA,
VLAN-Tag, IP-TOS
• Also supports queuing based on Marvell DSA Tag
• Layer2/3/4 frame encapsulation detection
• Supports long frames (up to 9K) on both receive
and transmit
• Hardware TCP/IP checksum on receive and
transmit
„ Three USB 2.0 ports
• Each port can act as USB host or peripheral
• USB 2.0 compliant
• Integrated USB 2.0 PHY
• EHCI compatible as a host
• As a host, supports direct connection to all
peripheral types (LS, FS, HS)
• As a peripheral, connects to all host types (HS, FS)
and hubs
• Up to six independent endpoints supporting control,
interrupt, bulk, and isochronous data transfers
• Dedicated DMA for data movement between
memory and port

Switching as defined in SATA working group PM
definition
- Port Selector (PS)—Issues the protocol-based
OOB sequence to select the active host port
• Supports device 48-bit addressing
• Supports ATA Tag Command Queuing
