A programmable logic device comprising a core circuit, a first circuit, a second circuit, and a third circuit. The core circuit may be configured to (i) operate at a first supply voltage, (ii) receive one or more internal input signals, and (iii) generate one or more internal output signals. The first circuit may be configured to generate said first supply voltage in response to a second supply voltage. The second circuit may be configured to (i) operate at a third supply voltage and (ii) generate said one or more internal input signals in response to one or more external input signals. The third circuit may be configured to (i) operate at said third supply voltage and (ii) generate one or more external output signals in response to said one or more internal output signals.

Multiple voltage supply programmable logic device

A product-term allocation architecture for a programmable device, comprising a plurality of logic gate sections and a fully rotatable, programmable OR-type array. A first one of the logic gate sections may comprise a first plurality of fixed logic gates. Each of the first plurality of fixed logic gates may have m inputs, m being an integer of at least one. A second one of the logic gate sections may comprise a second plurality of fixed logic gates. Each of the second plurality of fixed logic gates having n inputs, n being an integer of at least two and being different from m. The plurality of logic gate sections may be configured to provide p outputs, p being an integer equal to or greater than the total number of the fixed logic gates and less than the total number of fixed logic gate inputs. The fully rotatable, programmable OR-type array may receive the p outputs and may be configured to generate a plurality of array outputs.
