The E²Brain Solution
E²Brain (Embedded Electronic Brain) Computer-On-
Modules are a perfect fit for embedded applications
requiring RISC performance and low power consumption.
They support PowerPC, XScale and other processors in a
wide performance range.
All modules feature a common basic system and commu-
nications interface with PCI, LPC, I²C, Ethernet and seri-
al ports. A number of optional interfaces, including CAN,
UTOPIA and more, tailor the modules for specific appli-
cation areas. All modules are characterized by an excel-
lent performance/power consumption ratio qualifying
them for use in the extended temperature range
(-40° to 85°C).
E²Brain modules, like ETX, are installed on application
specific carrier boards providing the physical interfaces
for all used ports. Additional I/O and peripheral devices,
if necessary, are interfaced as PCI or LPC bus peripherals.
