4.3.7 Memory
4.3.7.1 DDR2 SDRAM
The SAM9N12/CN11 processor uses DDR2 SDRAM as the system memory. The DDR2 interface uses
1.8V power. The DDR2 chips and SAM9N12/CN11 processor are connected directly. The interface is
1.8V provided by an on-board voltage regulator.
VREF, which is half the interface voltage, or 0.9V, is provide
d by a simple voltage divider of 1.8V.
 One 1 Gbit DDR2-SDRAM memory (Micron MT47H64M16HR 8Meg*16*8), 16 bits data interface
connected to D[0-15].
4.3.7.2 NAND FLASH
The SAM9N12/CN11-EK has native support for NAND Flash memory and implements an 8-bit NAND
Flash w
ith 2 Gbits in size.
 One 2 Gbits NAND Flash (Micro MT29F2G08ABDHC), 16 bits data interface connected to D[0-15].
4.3.7.3 NOR FLASH
The SAM9N12/CN11-EK provides an optiona
l 128 Mbits of Flash memory using a chip-select signal.
The Flash memory is used with the 16-bit port size.
 One reserved position for 128 Mbits NOR Flash (Numonyx JS28F128P30TF75A).
