SBC330

GE SBC330 3U VPX Single Board Computer

The SBC330 is a 3U VPX Single Board Computer, and is part of GE Intelligent 

Platforms’ VPXtreme3 range of products. It uses the Freescale MPC8641D dual

core Integrated Host Processor, which contains two e600 PowerPC processing 

cores running at 1.0 to 1.5 GHz with dual DDR2 memory controllers, serial fabric 

and I/O interfaces. The SBC330 offers up to 2 GBytes of DDR2 SDRAM with ECC, 

up to 256 MBytes of Flash memory, two Gigabit Ethernet channels, on‐board 

serial communications (RS232), four USB2 ports, two SATA‐2.0 ports and two 

independent PCI Express links routed to the VPX backplane: a direct 8‐lane port 

for extreme graphics applications, and a 4‐lane port routed via an on‐board PCIe 

switch.

 The MPC8641D is connected to all on‐board PCI devices using PCI Express. This 

is a high‐speed serial interconnect running at 2.5 Gbits/second, providing a total 

bandwidth of 1 GBytes/second to and from the processor, through a non‐blocking 

switch architecture. PCI Express is software compatible with PCI and bridges are 

used where connection to PCI or PCI‐X components is required
