I need a small fpga with 2-4MB of RAM and nothing else
« on: June 27, 2022, 01:54:43 pm »
hi
I need a small board with an FPGA (I prefer Xilinx) with just SDRAM or something simpler than DRAM.
I don't want to use a IP-core to manage the ram, and I need to address up to 2 or 4Mbyte.

I don't need other gadgets on the board, I don't want e.g. 7segments LCDs, buttons, .. etc. Just soldered ram and a header with pins!

Is there anything that I can buy? I don't have the skill and the equipment to design and make one myself  :-//

I can also mention boards that I talked about a while ago, with Lattice ECP5 FPGAs (they are actually FPGA boards made for light controllers, that some company made dev base boards for). Relatively cheap and work well. They have 8 MBytes SDRAM (32-bit data bus, which is not bad). They also embed 2 Ethernet PHYs (but not the connectors, but normally all you'll need is MAGJACKs if you wanna implement Ethernet), just one user LED and many IOs. I have two of them, one with a ECP5-25 and one with a ECP5-45.

Chinese board with Spartan-6 (XC6SLX16) and MT48LC16M16A2 SDRAM chip: https://aliexpress.com/item/32801899786.html

Not Xilinx but the Gowin parts can come with built in PSRAM or SDRAM. The Sipeed Tang Nano 4k/9k are under $20 and have 8 Mbyte of PSRAM on chip.
