PPC405EP – PowerPC 405EP Embedded Processor
On-Chip Memory (OCM)
The OCM feature comprises a memory controller and a one-port 4KB static RAM (SRAM) accessed by the
processor core.
Features include:
PLB to PCI Interface
The PLB to PCI interface core provides a mechanism for connecting PCI devices to the local PowerPC processor
and local memory. This interface is compliant with version 2.2 of the PCI Specification.
