A state machine implemented controller is provided in which a logic coreis reconfigurable in response to state data held within a memory. Thus, on transition from one state to a next state the data held within the memoryis used to reconfigure the operation of the logic core. This enables a relatively compact logic coreto be used time and time again, thereby avoiding the need to individually define a logic core appropriate to each individual one of the states that the state machine can enter into. This results in a controller which is much more compact on an integrated circuit die than is the case with prior art controllers.

Controller for power supplies

A communication device is provided which transmits and responds to differential currents. Thereby allowing communication between devices that may be floating with respect to each other.
