Yes, the ASIC hardware is ultra-specialised, so it can really only calculate sha256(sha256(message)) < D, where "message" is the concatenation of the previous block's header, a proposed new block and a "nonce" (effectively a random number, though they are scanned in sequence).

This kind of thing is no use for, eg, breaking passwords, so if Bitcoin dies, the hardware is effectively useless.

https://www.bitcoinmining.com/ has a nice block diagram explaining this. See the "What Is Proof of Work" section.
