Ed,
There are also patents (pending) for their Instantaneous Processor Unit (IPU) which sounds like it can process analogue signals without the complexity of ADC then digital processing then DAC.
The sort of application might include a LED lighting controller, power factor controller for switched mode power supply, a maximum power point tracker for a solar panel, or a phase driver for a brushless dc motor etc. Any device that needs a little intelligence plus power electronics.
This aim appears to put control/intelligence onto the same die as a power transistor stage, and this value added feature would allow the existing UK Semiconductor Fabs to find new markets for their spare capacity, and help their business from being undercut by lower cost Chinese fabs.
They (SFN) have a sister company called WaferTrain which is going to follow the model of some of the low cost pcb manufacturers (eg pcbTrain) where multiple customers put their designs onto a single wafer, which goes through the fab, is sawn up into individual die, and customers get their packaged silicon back in two weeks.
I think this would appeal to universities and hobbyists, low cost and quick turn-around.
A standards library of digital and analogue cells, and hopefully open-source tools to allow chip layouts to be completed quickly with minimum errors will complete the offering
This article explains a lot more of the background to their business
