Mpc8313E Powerquicc Ii Pro Processor Overview - Freescale Semiconductor MPC8313E Family Reference Manual

Chapter 1
Overview
This chapter provides an overview of the MPC8313E PowerQUICC II Pro processor features, including a
block diagram showing the major functional components. The MPC8313E is a cost-effective, low-power,
highly integrated host processor that addresses the requirements of several printing and imaging,
consumer, and industrial applications, including main CPUs and I/O processors in printing systems,
networking switches and line cards, wireless LANs (WLANs), network access servers (NAS), VPN
routers, intelligent NIC, and industrial controllers. The MPC8313E extends the PowerQUICC family,
adding higher CPU performance, additional functionality, and faster interfaces while addressing the
requirements related to time-to-market, price, power consumption, and package size. This manual is
written from the perspective of the MPC8313E, and unless otherwise noted, the information applies also
to the MPC8313. Note that the MPC8313 does not support a security engine. The MPC8313E contains an
®
embedded PowerPC e300c3 core built on Power Architecture technology.

MPC8313E PowerQUICC II Pro Processor Overview

Figure 1-1 shows the major functional units within the MPC8313E. The e300c3 core in the MPC8313E,
with its 16 Kbytes of instruction and 16 Kbytes of data cache, implements the PowerPC user instruction
set architecture and provides hardware and software debugging support. In addition, the MPC8313E offers
dual three-speed 10, 100, and 1000 Mbps Ethernet controllers (eTSECs), a DDR1/DDR2 SDRAM
memory controller, an enhanced local bus controller (eLBC), a 32-bit PCI-2.3 controller, a dedicated
2
security engine, a programmable interrupt controller, dual I C controllers, a 4-channel DMA controller, a
general-purpose I/O port, and a USB 2.0 host and device controller with an on-chip high-speed USB 2.0
PHY. The high level of integration in the MPC8313E helps simplify board design and offers significant
bandwidth and performance.
