Push-button switches
•
6 push-button switches
-
1 CPU Reset
-
1 FPGA Reconfigure
-
4 user-defined inputs
•
Debounced by a Schmitt trigger circuit
•
Normally high; generates one active-low pulse when the switch is pressed
Slide switches
•
4 slide switches for user-defined inputs
•
When a switch is set to the DOWN or UP position (i.e., close to or away from the edge of
the DE3 board), it causes logic 0 or 1, respectively.
Clock inputs
•
50MHz oscillator
•
1 SMA connector for PLL clock output
•
1 SMA connector for external clock input
USB Host/Slave controller
•
Complies fully with Universal Serial Bus Specification Rev. 2.0
•
Support data transfer at high-speed, full-speed, and low-speed
•
Support both USB host and device
•

•
Support Programmed I/O (PIO) and Direct Memory Access (DMA)
Eight 180-pin
High Speed Terasic Connectors (HSTC) expansion headers
•
4 male and 4 female connectors are on the top and the bottom of DE3 board, respectively.
•
240 LVDS pairs of user-defined IO pins
•
Configurable I/O voltage for 3.3V, 2.5V, 1.8V, and 1.5V
Two 40-pin expansion headers
•
72
FPGA I/O pins, as well as 8 power and ground lines, are brought out to two 40-pin
expansion connectors
•
