EPCQ128ASI16N FAQs

Can EPCQ128ASI16N be used with all Intel FPGAs?

Answer: No. It is compatible with most Intel FPGAs that support Active Serial (AS) configuration mode, including Cyclone IV/V, MAX 10, and Arria series. Not suitable for FPGAs requiring JTAG-only boot.

What programming tools support EPCQ128ASI16N?

Answer: Intel's Quartus Prime software supports programming and configuration of the EPCQ128ASI16N via USB-Blaster or ByteBlaster programming cables.

How fast is the configuration process using x4 (quad-SPI) mode?

Answer: The maximum clock frequency is typically up to 100 MHz, and with quad-SPI (x4) enabled, the FPGA can be configured significantly faster compared to traditional single-bit serial flash.

Is in-system reprogramming supported?

Answer: Yes. The EPCQ128ASI16N supports in-system programming (ISP) through the Active Serial interface, which allows firmware updates without removing the chip from the board.

Can it store multiple images or partial reconfiguration files?

Answer: Yes, if the FPGA and design support it. The 128 Mb capacity allows multiple configuration images or room for partial reconfiguration files, especially in large-scale designs.
