Overview
Today’s small-to-medium business (SMB) and
consumer applications are driving the need for
highly integrated and cost effective solutions
that deliver high performance. The next
generation PowerQUICC
®
II Pro MPC837x
family provides an e300 core, built on Power
Architecture
®
technology, integrated with PCI
Express
®
and Serial-ATA (SATA) controllers,
as well as dual Gigabit Ethernet controllers,
to specifically address the needs of SMB and
consumer applications. The new MPC837x
family, based in 90 nm process technology,
provides high integration that simplifies board
design and offers a cost-effective solution that
is critical for applications such as wireless
access points, printers, network attached
storage and SMB routers.
e300 Platform Built on Power
Architecture Technology
The next generation MPC837x family utilizes
the 32-bit superscalar e300 core. It integrates
two integer units and a floating-point unit,
making it ideal for computational applications.
It supports 32 KB L1 data and instruction
cache, and has an operating frequency from
400 MHz to 800 MHz. The MPC837x family is
software compatible with existing 603e
core-based products.
Integrated Fabric Controllers
(PCI Express & Serial-ATA)
A key differentiator for the MPC837x family is
the integration of PCI Express and Serial-ATA
(SATA), which reduces the number of external
controller chips and provides customers with
a cost-effective solution. The PCI Express
controller is revision 1.0a compatible
and supports either x1 or x2 widths,
making it an excellent choice for wireless
access points and low-end printers. The
integrated SATA controllers support both
SATA I and II data rates (1.5 and 3.0 Gbaud),
providing integrated support for hard disk
drive applications such as network
attached storage.
