• Description: MPC107 Design Guide
• Manufacturer: Motorola / Freescale Semiconductor

1.1 Overview
The MPC107 is the newest generation of the PowerPC PCI/Memory controller family. The MPC107 is
upwardly compatible with the MPC106 at a software level, preserves all the essential hardware features of
the MPC106, and adds many new features, including:
The MPC107 also includes many other features, such as:
These features assist in designing embedded systems, but since they typically do not require any special
hardware support, they may be used or ignored, as determined by the system architecture. shows a
comparison of a typical MPC106-based system and the equivalent system based on the MPC107.
