NUMBERS OF SINGLE ENDED I/O OF EPCQ4ASI8N EPCQ-A

Hi there,

How do I determine the number of single ended digital input/outputs of the FPGA EPCQ4ASI8N EPCQ-A? cannot find the number in the datasheet.

Thanks

    Hi,
    EPCQ4A is no FPGA, it's a serial flash used as FPGA configuration device. It has two inputs, and four bidirectional I/Os when operated in ASx4 mode, but that's probably not what you are asking for.

    Hi Ibrahim,

    ​

    Thank you for reaching out Intel FPGA Community.

    ​

    Yes, EPCQ4ASI8N is not an FPGA, but it is a serial configuration device for FPGA.

    As refer to the datasheet, this device, specifically EPCQ4A, is only supports AS x1 only and not ASx4 configuration mode.

    ​

    Hence, based on the device's pin information, they only have two I/O pins (DATA0, DATA1). You can refer to below link for more information:

    Regards,

    Aqid
