• Manufacturer: Freescale Semiconductor, Inc

MPC8314E Features
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. A block diagram of the MPC8314E is shown in
