technology, with dual integer units enables
more efficient operations to be conducted
in parallel, resulting in a significant
of L1 instruction and data caches, dual integer
units and on-chip memory management units
(MMUs).
In summary, the MPC8309 provides users
with a highly integrated, fully programmable
communications processor helping to ensure
that a cost-effective system solution can be
quickly developed while offering the flexibility
to accommodate new standards and evolving
system requirements.

communications module offers a future-

by supporting programmable protocol

termination to meet evolving
QUICC Engine technology forms the heart
of the networking capability of the MPC830x
portfolio. The QUICC Engine block contains
several peripheral controllers and a 32-bit
RISC controller. Protocol support is provided
by the main workhorses of the device—the
unified communication controllers (UCCs).
Each of the five UCCs can support a variety
of communication protocols, including 10/100
Mbps Ethernet and high-level data link control
(HDLC). Two of the UCCs can also support
IEEE® 1588 version-2 time stamping.
