PPC405GPr Embedded Controller Functional Block Diagram
The PPC405GPr is designed using the IBM Microelectronics Blue LogicTM methodology in which major
functional blocks are integrated together to create an application-specific ASIC product. This approach
provides a consistent way to create complex ASICs using IBM CoreConnectTM Bus Architecture.
