Its advantage is that the specification is backed by a published data sheet, so the part can be designed into production equipment without further characterisation.
Its advantage is that it keeps a predictable function on the board across power cycles, which is what fixed hardware is for.
It is used in embedded control and instrumentation, where the specification has to hold over the life of the equipment.
