The board features 64MB of SDRAM with a single 64MB (32Mx16) SDRAM chip. The chip
consists of 16-bit data line, control line, and address line connected to the FPGA. This chip uses the
3.3V LVCMOS signaling standard. Connections between the FPGA and SDRAM are shown in
Figure 3-19
, and the pin assignment is listed in
Table 3-13.
