Integrated Communications Processors
MPC8306 and MPC8306S
PowerQUICC II Pro Processors
Overview
The MPC8306 and MPC8306S processors
are part of the ultra low-end MPC830x
communications processor portfolio based
on the e300 core architecture. They address
the requirements of networking applications,
including I/O cards for low-end base stations,
residential gateways, modem/routers,
industrial control, factory automation and test
and measurement applications. The MPC830x
portfolio extends current PowerQUICC
offerings, providing similar DMIPS/MHz in
CPU performance, additional functionality
and faster interfaces while maintaining
code compatibility with PowerQUICC I
and PowerQUICC II processors. MPC830x
processors also provide competitive pricing,
low power consumption, compact board
footprint and a time to market advantage
through cost-effective evaluation kits with
optimized BSP and drivers.

USB 2.0 controller, a 16-bit local bus and two
direct memory access (DMA) channels. In
addition, the MPC8306 also features 4 x CAN
and an enhanced SDHC controller.
In summary, the MPC8306S and MPC8306
devices provide users with a highly integrated,
fully programmable communications
processor for use in many networking and
industrial control applications. This helps
ensure that a cost-effective system solution
can be quickly developed and will offer
flexibility to accommodate new standards
and evolving system requirements.
QUICC Engine Technology
A communications complex, based on
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
(MPC8306 configuration only).
