Use Microchip SST25V series to configure Altera's Cyclone IV

We have earlier used M25P64 flash as configuration memory, but this family is EOL soon.

Microchip SST25V series looks both cheap and available.

For a new design based on Cyclone IV I am looking för a 16Mbit flash.

Would Microchip SST25VF016B-50-4I-S2AF work (in AS configuration mode) ?

Yes, I know the devices labeled Altera/Intel, but with the stupid Altera-pricing you don't even want to ask for "your price".

    Yes, that device should be fine. You could also consider serial FLASH devices from Micron or ST.

    Cheers,

    EPCS is is not Intel inside, it's Micron inside;)

    The MT25-series from Mircon could be a good replacement for the old M25 i guess.

    Even if the MT25 supports dual I/O for higher transfer rates, it will boot in standard "single-channel-SPI".

    Today a 128Mbit flash costs nothing, and gives great opportunities for example to have more than one FPGA project inside.
