Abstract
A programmable system-on-a-chip integrated circuit device includes a programmable logic block, at least one user non-volatile memory block, and voltage-measuring and control analog and digital circuits on a single semiconductor integrated circuit chip or a flip chip, face-to-face, or other multiple die configuration. The programmable system-on-a-chip integrated circuit with voltage-measuring, current-measuring and control circuitry performs voltage measurement and control functions and can be used to control and monitor external power supplies connected to external loads.
Claims11
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 including an analog-to-digital converter;
- an analog input/output circuit block including, at least one voltage-measuring circuit coupled to a first I/O pad, and at least one programmable MOSFET gate-drive circuit coupled to a second I/O pad;
- and
- 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.
