EP2C8Q208C8 ROM problems

[lgeorge123]

I search the data sheet of EP2C8Q208C8 cannot find the ROM SIZE of it , so is it have no ROM or what is the size of it if it have ??

I search the data sheet

Cyclone® II devices feature embedded memory structures to address the on-chip memory needs of FPGA designs. The embedded memory structure consists of columns of M4K memory blocks that can be configured to provide various memory functions such as RAM, first-in first-out (FIFO) buffers, and ROM.

EP2C8 has 144 respectively 165 kBit available (8 resp. 9 Bit organisation).

I don't think there's any ROM in FPGA, all you need is ram, because ram can be simulated as rom.
and if you need a rom to store your code, just use EPCS device

Hi , sicheng163 , can you give me more information about using EPCS , can EP2C8Q208C8 using it without external ROM ?

EPCS series chips are configrution devices for altera FPGAs,
such as EPCS4/EPCS16
of course you can design a FPGA board without ROM, then you have to download your code with JTAG everytime after power up,

what configration I need in quartus in order to store my code in rom ???

Actually you don't really need to config anything, just download your code into EPCS chip, with AS mode JTAG form quartus programmer (Active Serial Programming)
then when power up, FPGA will get the code from EPCS,
so, all you need is AS mode JTAG and an EPCS chip and a FPGA
you can get more details from the datasheet of EPCS

according to EPCS64 datasheet it is a 64M bit memory IC , can it used to store 4M size code without flash memory ???

EPCS64 is exactly a flash memory, read carefully the first page of datasheet!
