405GP – Power PC 405GP Embedded Processor
SDRAM Memory Controller
The PPC405GP Memory Controller core provides a low latency access path to SDRAM memory. A variety of
system memory configurations are supported. The memory controller supports up to four physical banks. Up to
256MB per bank are supported, up to a maximum of 1GB. Memory timings, address and bank sizes, and memory
addressing modes are programmable.
Features include:
External Peripheral Bus Controller (EBC)
