The entries on each chip in the link you provided include links to the respective datasheets, though admittedly not every link works. The link to the Sfards github repo includes a datasheet that describes the protocol that one uses to communicate with the chip. The Bitmine Coincraft one also has some protocol information. I didn't look at all of them, there may be better ones that the examples I've listed.
