A friend and I have been discussing about wether we can controll up to 5 led matrixes of 5x7 linked together with the IC mm5450 using i²c. These are the datasheets:

https://www.electro-tech-online.com/custompdfs/2004/11/disp-11.pdf (led display)
We intend to use only one color of the display. I thought we should be able to controll every led led just by setting the corresponding row+column.. But this is our first project concerning such ic's.. We can't find any circuits with this mm5450 ic... So does anyone know if we are right?
