PowerQUICC II Pro Processor
Hardware Specifications
This document provides an overview of the MPC8314E
PowerQUICC™ II Pro processor features, including a block
diagram showing the major functional components. The
MPC8314E contains a core built on Power Architecture™
technology. It is a cost-effective, low-power, highly
integrated host processor that addresses the requirements of
several storage, consumer, and industrial applications,
including main CPUs and I/O processors in network attached
storage (NAS), voice over IP (VoIP) router/gateway,
intelligent wireless LAN (WLAN), set top boxes, industrial
controllers, and wireless access points. The MPC8314E
extends the PowerQUICC II Pro family, adding higher CPU
performance, new functionality, and faster interfaces while
addressing the requirements related to time-to-market, price,
power consumption, and package size. Note that while the
MPC8314E supports a security engine, the MPC8314 does
not.

Overview
The MPC8314E incorporates the e300c3 (MPC603e-based) core, which includes 16 Kbytes of L1
instruction and data caches, on-chip memory management units (MMUs), and floating-point support. In
addition to the e300 core, the SoC platform includes features such as dual enhanced three-speed 10, 100,
1000 Mbps Ethernet controllers (eTSECs) with SGMII support, a 32- or 16-bit DDR1/DDR2 SDRAM
memory controller, a security engine to accelerate control and data plane security protocols, and a high
degree of software compatibility with previous-generation PowerQUICC processor-based designs for
backward compatibility and easier software migration. The MPC8314E also offers peripheral interfaces
such as a 32-bit PCI interface with up to 66 MHz operation, 16-bit enhanced local bus interface with up to
66 MHz operation, TDM interface, and USB 2.0 with an on-chip USB 2.0 PHY.
8314E offers additional high-speed interconnect support with dual single-lane PCI Express interfaces.
When not used for PCI Express, the SerDes interface may be configured to support SGMII. The
MPC8314E security engine (SEC 3.3) allows CPU-intensive cryptographic operations to be offloaded
from the main CPU core. This figure shows a block diagram of the MPC8314E.
