Reference Manual

Table 2–38 lists the I

C EEPROM pin assignments, signal names, and functions. The

signal names and types are relative to the Cyclone V SoC in terms of I/O setting and

direction.

Power Supply

You can power up the development board from a laptop-style DC power input or

through the DC auxiliary connector. The Cyclone V SoC is designed in such way that

the power rails for the HPS and FPGA are independent, allowing power down for the

FPGA side when the HPS side is running. This eliminates power consumption on the

FPGA part when not in use.

Table 2–39 lists the maximum allowed draws of the power input.

An on-board multi-channel analog-to-digital converter (ADC) measures the current

for several specific board rails.
