Freescale Semiconductor

Overview

1Overview

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.
