The LPDDR2 interface schematic varies, depending upon the width of the LPDDR2 devices used. Figure 5-79 shows the schematic connections for 16-bit interface using one x16 LPDDR2 device. Two x16 LPDDR2 devices are supported for twin-die configuration which embeds two devices in the same package.
Figure 5-80 shows the schematic connections for 32-bit interface using one x32 LPDDR2 device.
When not using a part of LPDDR2 interface (using x16 or not using the LPDDR2 interface):
Note: All the unused DDR ADDR_CTRL lines used for DDR3 operation should be left as NC.
