includes industry-leading embedded
vendors who provide host processors,
The MPC8548E device is the first
integrated communications processor to
comply with the Serial RapidIO interconnect
specification, Revision 1.2, from the RapidIO
Trade Association. The RapidIO serial fabric
interface is ideal for connecting MPC8548
processors and peripherals in high-performance
distributed systems. Examples include control
plane processing, protocol processing and
other compute-intensive applications requiring
high-speed, peer-level communications with
a low pin count, such as those found in
AdvancedTCA® platforms.

The 90 nm PowerQUICC III family includes
the MPC8548E, MPC8547E, MPC8545E
and MPC8543E.
The MPC8547 is targeted toward storage
markets, the MPC8545 includes features
for printing and imaging markets and the
MPC8543 is targeted at general purpose
data plane processing requirements—
rounding out the product family.
High-Speed Connectivity
Freescale’s MPC8548E processor offers
a wide range of high-speed connectivity
options, including enhanced Triple Speed
Ethernet, serial RapidIO interconnect
technology and PCI Express. Support
for these high-speed interfaces enables
scalable connectivity to network processors
and/or ASICs in the data plane while
the PowerQUICC III handles complex,
computationally demanding control plane
processing tasks. These processors also
feature next-generation double data rate
(DDR2) memory controllers, enhanced Gigabit
Ethernet support, double precision floating
point and integrated security engines that
support the Kasumi algorithm needed for
3G wireless security. In addition, support is
provided for exclusive OR (XOR) acceleration
needed for parity in storage applications.
