MPC8378E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2

Freescale Semiconductor

Overview

2.0 dual-role controller, a programmable interrupt controller, dual I2C controllers, a 4-channel DMA

controller, an enhanced secured digital host controller, and a general-purpose I/O port. The block diagram

of the MPC8378E is shown in Figure 1.

Figure 1. MPC8378E Block Diagram and Features

The following features are supported in the MPC8378E:

•

e300c4s core built on Power Architecture™ technology with 32-Kbyte instruction cache and

32-Kbyte data cache, a floating point unit, and two integer units

•

DDR1/DDR2 memory controller supporting a 32/64-bit interface

•

Peripheral interfaces, such as a 32-bit PCI interface with up to 66-MHz operation

•

32-bit local bus interface running up to 133-MHz

•

USB 2.0 (full/high speed) support

•

Power management controller for low-power consumption

•

High degree of software compatibility with previous-generation PowerQUICC processor-based

designs for backward compatibility and easier software migration

•

Optional security engine provides acceleration for control and data plane security protocols

The optional security engine (SEC 3.0) is noted with the extension “E” at the end. It allows CPU-intensive

cryptographic operations to be offloaded from the main CPU core. The security-processing accelerator

provides hardware acceleration for the DES, 3DES, AES, SHA-1, and MD-5 algorithms.
