MAX10 FPGA on-chip memory size question

Hi,

in the datasheet of the MAX10 FPGA type10M50DAF484C8GES I read that the on-chip memory has a size of 1,677,312 kbits.

This means a size of more than 209 MBye. This seems to be extremely large.

Is this correct?

Second question:

I want to devide this on-chip memory into 24 FIFOs of 2 MByte, 12 bit wide.

Can I do this?

Thank you.

Regards.

    For a 10M50 my datasheet says M9K memory (Kb = Kbytes?) is 1638. I take this as 1638 x 1024 =1677312 bits. So ... 1677312/1024= ~1638 KBytes ~= 1.6 MB.

    MAx 10 never own such huge capacity of memory for that cost... else the cyclone V and Arria 10 can retire already...

    and max 10 implementation need to be careful as you can easily used up those spaces.

    it is in bits not kbits so: 1,677,312 bits == 205KBytes of memory.

    Hi,somewhere I read about 1,677,312 kbits.I can not find it anymore. But I was suspicious about this huge amount !

    Thanks for making it clear.!

    Regards.
