FPGA_PROG_B Pushbutton SwitchThe SP601 provides one dedicated, active low FPGA_PROG_B pushbutton switch, asshown in Figure 1-28.Power ManagementAC Adapter and 5V Input Power Jack/SwitchThe SP601 is powered from a 5V source that is connected through a 2.1mm x 5.5mm typeplug (center positive). SP601 power can be turned on or off through a board mounted slideswitch. When the switch is in the on position, a green LED (DS15) is illuminated.Onboard Power SuppliesThe diagram in Figure 1-30 shows the power supply architecture and maximum currenthandling on each supply. The typical operating currents are significantly below themaximum capable. The board is normally shipped with a 15W power supply, whichshould be sufficient for most applications.X-Ref Target - Figure 1-28Figure 1-28: FPGA_PROG_B Pushbutton Switch TopologyTable 1-21: FPGA_PROG_B Pushbutton Switch ConnectionsFPGA U1 Pin Schematic Netname SW3 PinV2 FPGA_PROG_B 1X-Ref Target - Figure 1-29NET "FPGA_PROG_B" LOC = "V2";Figure 1-29: UCF Location Constraints for BPI Flash ConnectionsVCC2V5FPGA PROG BPushbuttonR244.7K5%1/16W121 P1P2P4P3243SW3UG518_28_070809 |
