MPC8314E PowerQUICC II Pro Processor Hardware Specifications, Rev. 2

Freescale Semiconductor

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.
