Programmable system on a chip

A programmable system-on-a-chip integrated circuit device comprising:

• a programmable logic block
• a digital input/output circuit block;
• a non-volatile memory block;
• an analog circuit block;
• an analog input/output circuit block;
• a programmable interconnect architecture including programmable elements and interconnect conductors, ones of said programmable elements coupled to said programmable logic block, said non-volatile memory block, said analog circuit block, said analog input/output circuit block, said digital input/output circuit block, and to said interconnect conductors, such that inputs and outputs of said programmable logic block, said non-volatile memory block, said analog circuit block, said analog input/output circuit block, and said digital input/output circuit block can be programmably coupled to one another;
• and
• a system controller block including a power-up controller configured to apply system power to said programmable logic block, said digital input/output circuit block, said non-volatile memory block, said analog circuit block, and said analog input/output circuit block in a predetermined sequence and a system supervisor block coupled to at least one of said programmable logic block, said digital input/output circuit block, said non-volatile memory block, said analog circuit block, and said analog input/output circuit block, and configured to monitor at least one function of at least one circuit external to the programmable system-on-a-chip integrated circuit device.
