• Manufacturer Part Number: MPC8321E
• Description: Mpc8321e Powerquicc Ii Pro Processor
• Manufacturer: Freescale Semiconductor, Inc

Overview
1
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
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.
