Key Features
The MPC8548E networking/telecom processor
features an embedded e500 core, targeting
up to a 1.5 GHz core operation, an integrated
security engine, 64-bit DDR/ DDR2 controller
scaling up to 667 MHz data rate, dual 32-bit
PCI or 64-bit PCI-X, 4-bit serial RapidIO
®
fabric technology and 4-bit PCI Express
®
(or single 8-bit PCI Express 1.0a), local bus
I/O interfaces and four Gigabit Ethernet
interfaces. The combination of these features
makes this device an optimal communications
processing solution for Ethernet-only or
RapidIO interworking applications, such as
enterprise networking, telecom transmission
and switching and 3G wireless base stations.
The security engine includes Kasumi
algorithm acceleration, making the MPC8548E
an ideal choice for enhancing security
protocol processing in 2.5G and 3G wireless
network infrastructure. This device’s
integrated security also includes XOR
acceleration, which enhances system
performance by offloading the compute-
intensive parity check in small-medium
business enterprise and redundant array
of inexpensive disk storage applications.
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 PowerQUICC
™
III RapidIO ecosystem
is more than 50 members strong and
includes industry-leading embedded
vendors who provide host processors,
DSPs, communications processors,
backplane interfaces, switches, systems,
tools, operating systems and services.
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.
