PRODUCTION DATA.
The DDR3 interface schematic varies, depending upon the width of the DDR3 devices used. Figure 7-47 shows the schematic connections for 16-bit interface on the AM335x device using one x16 DDR3 device and Figure 7-49 shows the schematic connections for 16-bit interface on the AM335x device using two x8 DDR3 devices. The AM335x DDR3 memory interface only supports 16-bit wide mode of operation. The AM335x device can only source one load connected to the DQS[x] and DQ[x] net class signals and two loads connected to the CK and ADDR_CTRL net class signals. For more information related to net classes, see Section 7.7.2.3.3.8.
