Chapter 2: <strong>Board</strong> Components 2–49Power SupplyPower SupplyTable 2–38 lists the I 2 C EEPROM pin assignments, signal names, and functions. Thesignal names and types are relative to the <strong>Cyclone</strong> V <strong>SoC</strong> in terms of I/O setting anddirection.Table 2–38.

The <strong>Cyclone</strong> V <strong>SoC</strong> is designed in such way thatthe power rails for the HPS and <strong>FPGA</strong> are independent, allowing power down for the<strong>FPGA</strong> side when the HPS side is running. This eliminates power consumption on the<strong>FPGA</strong> part when not in use.Table 2–39 lists the maximum allowed draws of the power input.Table 2–39.
