Integrated Communications Processors
MPC8272 PowerQUICC
™
II Processor Family
The high-performance MPC8272
PowerQUICC™ II processor family, built on
Power Architecture™ technology, addresses
the cost-sensitive needs of a wide variety of
networking and communications applications.
By offering integrated hardware security, the
MPC8272 family is well suited for networking
equipment requiring encryption capabilities,
such as small and medium enterprise (SME)
routers, virtual private network (VPN) and
firewall routers, wireless access points,
residential gateways and xDSL equipment,
as well as imaging, industrial control and
test and measurement equipment.
Delivering an ideal combination of price,
performance and low-power operation, the
MPC8272 family supports CPU frequencies
ranging from 266 MHz to 400 MHz while
offering the benefits of low power consumption
(0.8 watts at 266 MHz). The family’s high level
of on-chip integration and small footprint
enable developers to reduce board space.
The MPC8272 family includes the MPC8247,
MPC8248, MPC8271 and MPC8272 processors.
Each device integrates two processing blocks:
an embedded 603e™ core, built on Power
Architecture technology, and a RISC-based
Communications Processor Module (CPM).
This dual-core architecture is designed to
reduce power consumption and offer a more
balanced approach to processing than
traditional processor architectures. The CPM
offloads low-level peripheral communications
tasks, enabling the embedded Power
Architecture core to manage high-level
processing tasks. The MPC8272 family
supports a variety of protocols and interfaces,
including dual fast Ethernet MACs, ATM,
HDLC, a 32-bit 33/66 MHz PCI interface
and a USB host/device interface.
The MPC8248 and MPC8272 processors
feature a security engine that supports
DES, 3DES, MD-5, SHA-1, AES and ARC-4
encryption algorithms. The processors also
offer a public key accelerator and on-chip
random number generator. This embedded
security core is derived from Freescale’s
security coprocessor product line. The core
offers the same direct-memory access
(DMA) and parallel processing capabilities as
Freescale’s security coprocessor product line
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.
On-chip security makes the MPC8272 family
an optimal solution for applications that
require security features in concert with high
performance and low system-level cost.
