Due to the non-volatile nature of SPI FLASH, it can be used as a boot device for the system to store the boot image of the system. These images mainly include FPGA bit files, core application code and other user data files.

Page 9: Part 4: Fpga Power Supply
ALINX ALTERA Core Board AC4075 User Manual nCSO DATA0 ASDO Part 4: FPGA Power Supply In order for FGPA to work properly, we need to provide 3.3V, 1.8V, 2.5V, 1.2V and VCCIO five-way power for the FPGA. Let's talk about the power pin portion of the FPGA, which includes the power pins for each bank, the core voltage pins, the analog voltage, and the phase-locked loop power supply pins. - Page 10 ALINX ALTERA Core Board AC4075 User Manual capacitors are used to ensure the system's power supply is stable and reliable. The three-way DCDC power supply circuit is designed as follows: Figure 4-1: DC-DC Power Supply Schematic The other two channels (3.3V and 2.5V) use less LDO chips SPX3819M5-L-3-3 and SPX3819M5-L-2-5 because of the low current required.
