Overview
The MPC8323E incorporates the e300c2 (MPC603e-based) core built on Power Architecture®
technology, which includes 16 Kbytes of L1 instruction and data caches, dual integer units, and on-chip
memory management units (MMUs). The e300c2 core does not contain a floating point unit (FPU). The
MPC8323E also includes a 32-bit PCI controller, four DMA channels, a security engine, and a 32-bit
DDR1/DDR2 memory controller.
A new communications complex based on QUICC Engine technology forms the heart of the networking
capability of the MPC8323E. 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). Note that the MPC8321 and MPC8321E do not support UTOPIA. A
block diagram of the MPC8323E is shown in
Figure 1.

Each of the five UCCs can support a variety of communication protocols: 10/100 Mbps Ethernet, serial
ATM, HDLC, UART, and BISYNC—and, in the MPC8323E and MPC8323, multi-PHY ATM and ATM
support for up to OC-3 speeds.

Overview
NOTE
The QUICC Engine block can also support a UTOPIA level 2 capable of
supporting 31 multi-PHY (MPC8323E- and MPC8323-specific).
The MPC8323E security engine (SEC 2.2) allows CPU-intensive cryptographic operations to be offloaded
from the main CPU core. The security-processing accelerator provides hardware acceleration for the DES,
3DES, AES, SHA-1, and MD-5 algorithms.
In summary, the MPC8323E family provides users with a highly integrated, fully programmable
communications processor. This helps ensure that a low-cost system solution can be quickly developed
and offers flexibility to accommodate new standards and evolving system requirements.
