1K LUTs with 5 I/O's, My thought was an RGB LED controller with an i2c bus but that is already available in hard logic. You could probably do the motor sequencing bit for a motor controller in it, doing i2c for reading the position sensors. But mostly I run up against pin limitations. I'd like it to have 12 I/Os rather than 5 presumably Lattice provides that too. Then its a replacement for the CoolRunner CPLDs.
