Power supplies
and
The product embeds a dual power supply for EBI. VDDNF for NAND Flash signals and VDDIOM
for others. This allows to use an 1.8V or 3.3V NAND Flash independently of SDRAM power
supply.
A switch, NFD0_ON_D16, enables the user to select NAND Flash path on D0-D15 or D16-D32
depending on memory power supplies. This switch is located in the register EBICSA in the Bus
Matrix user interface.
In the following example the NAND Flash and the external RAM (DDR2 or LP-DDR or 16-bit LP-
SDR) are in the same power supply range, (NFD0_ON_D16 = default).
– A[14] <=> DELAY6[27:24]
– A[15] <=> DELAY6[31:28]
– A[16] <=> DELAY7[3:0]
– A[17] <=> DELAY7[7:4]
– A[18] <=> DELAY7[11:8]
– A19 <=> DELAY7[15:12]
– A21 <=> PD[2] <=> DELAY7[23:20]
– A22 <=> PD[3] <=> DELAY7[27:24]
