Chapter 1

Overview

The MPC8540 integrates a PowerPC™ processor core with system logic required for networking,

storage, and general-purpose embedded applications. The MPC8540 is a member of a growing

family of products that combine system-level support for industry standard interfaces to

processors that implement the PowerPC architecture. This chapter provides a high-level

description of the features and functionality of the MPC8540 integrated microprocessor.

1.1

Introduction

The MPC8540 uses the e500 core and RapidIO interconnect technology to balance processor

performance with I/O system throughput. The e500 core implements the enhanced Book E

instruction set architecture and provides unprecedented levels of hardware and software

debugging support.

In addition, the MPC8540 offers 256 Kbytes of L2 cache, 2 integrated 10/100/1Gb three-speed

Ethernet controllers (TSECs), a 10/100 maintenance port, a DDR SDRAM memory controller, a

64-bit PCI/PCI-X controller, an 8-bit RapidIO port, a programmable interrupt controller (PIC), an

I2C controller, a 4-channel DMA controller, a general-purpose I/O port, and a dual universal

asynchronous receiver/transmitter (DUART). The high level of integration in the MPC8540

simplifies board design and offers significant bandwidth and performance.
