• Description: Powerpc 440ep Embedded Processor
• Manufacturer: Applied Micro Circuits Corporation (AMCC)

External Peripheral Bus Controller (EBC)
Features include:
Ethernet Controller Interface
Ethernet support provided by the PPC440EP interfaces to the physical layer but the PHY is not included on the
chip:
DMA to PLB3 Controller
This DMA controller provides a DMA interface between the OPB and the 64-bit PLB.
