MPC8315E
PowerQUICC II Pro Processor
Hardware Specifications
This document provides an overview of the MPC8315E
PowerQUICC™ II Pro processor features, including a block
diagram showing the major functional components. The
MPC8315E 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 MPC8315E
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
MPC8315E supports a security engine, the MPC8315 does
not.

Overview
The MPC8315E 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, dual SATA 3 Gbps controllers (MPC8315E-specific), 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 MPC8315E 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.
The MPC8315E offers additional high-speed interconnect support with dual integrated SATA 3 Gbps
interfaces and dual single-lane PCI Express interfaces. When not used for PCI Express, the SerDes
interface may be configured to support SGMII. The MPC8315E 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 MPC8315E.
