Max10 PCB Layout - Unused Pins

Hello, I am building my first from-scratch FPGA project. I’m using a Max10 10M02SC 153-MBGA, but my design is really simple. I really only need to use one bank because I only need about 16 I...

Newtham,

MAX10's internal clock is definitely nice, but if your logic depends on certain clock speed, you shouldn't use it. If your design can tolerate 55~116MHz variation, you are all good. Depending on the silicon batch(lot), one MAX10 generates 55Mhz, and other ones generate 116MHz. Once it runs at a clock frequency, it stays on that frequency which I've been told. However if you are building many boards, each board would have different clock speed depending on silicon batch(lot).

If you have space on your board, use bigger footprint part. It costs more to build smaller, and it could get somewhat complicated.

Regards,
