New Yorke chip in hardware

[EdS2]

I too am finding it hard to see applicability for my interests in Google's offer of free chips: FPGAs do tick a lot of boxes. It's an attractive offer on the face of it, but I was reminded how very involved and exacting the chip design process is. You'd very likely want to bring up your design on an FPGA before finalising your design anyway.

The very low power Lattice offerings are a good find!

Two disadvantages for me: only available in BGA packages, and not 5V tolerant. These are of course minor points, especially for a new standalone calculator-type of application.

An advantage (for me) of Lattice's ICE40 range, hopefully including these low power ones: an open source toolchain is available.
