command input signals DDR2_CS_N[1..0] and presence-detect address input signals
DDR2_SA[1..0]. Users should never use the DDR2 SO-DIMM socket and the HSTC connector B at
the same time.
Figure 2.16
shows the connections between the DDR2 SO-DIMM socket and Stratix
III device. The pin assignments are listed in
Table A-14

Using the USB OTG
The DE3 board provides both USB host and device interfaces using the Philips ISP1761ET
single-chip USB controller. The host and device controllers are compliant with the Universal Serial
Bus Specification Rev. 2.0, supporting data transfer at high-speed (480 Mbit/s), full-speed (12
Mbit/s) and low-speed (1.5 Mbit/s).
Figure 2.17
shows the connection between the USB OTG and
Stratix III device. The port 1 can be configured as a downstream port, or an upstream port or OTG
port. If the port 1 is configured as an OTG port, users can use JP1 to specify host or peripheral role,
as listed in
Table 2-4
. The pin assignments for the associated interface are listed in
Table A-15
.
