Static Memory Controller
DDR2SDRAM Controller
In the following example the NAND Flash and the external RAM (DDR2 or LP-DDR or 16bit LP-
SDR) are NOT in the same power supply range (NFD0_ON_D16 = 1).
This can be used if the SMC connects to the NAND Flash only. Using this function with another
device on the SMC will lead to an unpredictable behavior of that device. In that case, the default
value must be selected.
At reset NFD0_ON_D16 = 0 and NAND Flash bus is connected to D0-D15.
For information on the Static Memory Controller, refer to the Static Memory Controller section.
The product embeds a multi-port DDR2SDR Controller. This allows to use three additional ports
on DDR2SDRC to lessen the EBI load from a part of DDR2 or LP-DDR accesses. This
increases the bandwidth when DDR2 and NAND Flash devices are used. This feature is NOT
compatible with SDR or LP-SDR Memory.
It is controlled by DDR_MP_EN bit in EBI Chip Select Assignment Register.
