4.2.1.3 P4080 USB and Mass Storage
The P4080 has two multiplexed USB-MAC integrated which have the pins multiplexed with the
three speed Ethernet Controller 1/2.
To connect a mass storage device, USB Host port 1 is used. This USB port is then connected to
a modular flash disk module with USB2.0 interface that provides up to 16GB of user flash. The
device initially used is the SmartModulear (SG9ED52M4GGCNEMR) with 4GB of memory.
The second USB port is routed to the front panel and accessible for external USB-devices.
4.2.1.4 P4080 Serdes Configuration
The Freescale P4080 provides 18 Serdes lanes that can be mapped to different IO-Interfaces.
The following interfaces are required:
 2x PCI-Express, one to the RTM, one to the switch
 1x SRIO
 1x XAUI to the switch
 2x SGMII to the switch
4.2.1.5 Freescale P4080 PCI-Express
The Freescale P4080 provides three PCI Express 2.0 controllers running up to 5 GHz. Two of
them are used on the ATCA-8310. Both interfaces are run with 2.5GHz.
Two lanes are routed to the switch. One lane is routed to the RTM via Zone 3.
4.2.1.6 Freescale P4080 Serial Rapid IO SRIO
The Freescale P4080 provides two serial RapidIO 1.2 controllers running at up to 3.125 GHz.
One of them is used to connect to the SRIO switch device. The configuration is x1 and the speed
is 2.5GHz.
Both controllers are connected to the SRIO-switch.
