DRAM controller

The DRAM controller (available only on 473-pin devices) is a multi-port controller that monitors

incoming requests on the three AHB slave ports and decides (at each rising clock edge) what command

needs to be sent to the external DRAM.

The DRAM controller on this device supports the following types of memories:

•

Mobile DDR (mDDR)
