P1V - with Lattice ECP5 FPGAs?

  • Interesting to read about the TinyFPGA EX progress, as haven't checked it out in a while. In some earlier work I did I found that the Lattice ECP5 FPGA family is pretty much an ideal match for a low cost complete P1V implementation with room for some extra peripherals. Specifically the ECP5 LFE5U-25F FPGA variant was a real sweet spot. Pity that part is not one of the targets of the TinyFPGA EX though as Luke seems to have chosen the 12F, 45F, and 85F parts for his board. So you would need to either get the -45F model or above for a full 8 COG P1V and this leaves heaps of spare space, maybe you could even squeeze two bare bones P1Vs in it or a 16 COG variant with some redesign of the hub.
