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

PCI Interface
The PCI interface allows connection of PCI devices to the PowerPC processor and local memory. This interface is
designed to Version 2.2 of the PCI Specification and supports 32- bit PCI devices.
Reference Specifications:
Features include:
DDR SDRAM Memory Controller
The Double Data Rate (DDR) SDRAM memory controller supports industry standard discrete devices. Up to four
256MB logical banks are supported in limited configurations. Global memory timings, address and bank sizes, and
memory addressing modes are programmable.
Features include:
