III integrated communications processor
incorporates a wide range of advanced
Freescale technologies, modular cores
and peripherals. Leveraging Freescale’s
system-on-chip (SoC) PowerQUICC III
platform architecture, the MPC8541E
combines the powerful e500 core, built
on Power Architecture

The MPC8541E device’s high level of
integration helps simplify board design and
enhances overall system-level bandwidth
and performance. In addition to the e500 core
and 256 KB of Level 2 (L2) cache memory,
the MPC8541E features an integrated security
engine, a double data rate (DDR) SDRAM
memory controller, dual Gigabit Ethernet
controllers, a four-channel DMA controller,
dual asynchronous receiver/transmitters
(DUART), local bus controller and a 64-bit
PCI controller that can also serve as two
32-bit PCI ports. Dual on-chip PCI support
provides a cost-effective alternative to
separate, discrete PCI bridges and chipsets
for I/O-intensive applications that require
multiple PCI interfaces. The MPC8541E also
supports Communications Processor Module
(CPM) capabilities, such as dual 10/100 Fast
Ethernet controllers, I C controller and a serial

Integrated Security
The MPC8541E processor features a security
engine that supports DES, 3DES, MD-5, SHA-1,
AES and ARC-4 encryption algorithms and
offers a public key accelerator and on-chip
random number generator. This embedded
security core is derived from Freescale’s
security coprocessor product line and offers
the same direct memory access (DMA) and
parallel processing capabilities, as well as the
ability to perform single-pass encryption and
authentication as required by widely used
security protocols, such as IPsec and 802.11i.
Integrated security makes the MPC8541E an
optimal communications processor solution
for applications that require security features
in concert with high performance and low
system-level cost.
Wide Range of Applications
With its high-performance core, I/O
peripherals and integrated security
engine, the MPC8541E processor offers a
powerful control element for networking,
communications and general-purpose
embedded applications. The MPC8541E
serves as an optimal host-processing
solution for a multitude of compute-intensive
applications, such as VPN and firewall routers,
enterprise-class storage systems, Ethernet
switching equipment, SOHO, enterprise router,
business-class imaging equipment and
general-purpose embedded applications.
