Revision 1.30 – February 27, 2009
DDR2/1 SDRAM Memory Controller
The Double Data Rate 2/1 (DDR2/1) SDRAM memory controller supports industry standard discrete devices that
are compatible with both the DDR1 or DDR2 specifications. The correct I/O supply voltage must be provided for the
two types of DDR devices: DDR1 devices require +2.5V and DDR2 devices require +1.8V.
Global memory timings, address and bank sizes, and memory addressing modes are programmable.
Features include:
External Peripheral Bus Controller (EBC)
Features include:
AMCC Proprietary
