Abstract: A multi-functional programmable I/O buffer in a Field Programmable Gate Array (FPGA) device. The I/O buffer is programmably configurable to meet any of a wide range of I/O standards, be it single ended or differential, 5V, 3.3V, 2.5V or 1.5V logic, without the need for implementing multiple I/O buffers to properly handle each different iteration of I/O requirements. An embedded, internal programmable resistor (e.g., a programmable 100 ohm resistor) is programmably selected for use in differential I/O applications, thus eliminating the conventional requirement for the use of an external resistor connected to each differential receiver I/O pin. The present invention also separates I/O pads into groups in each of a plurality of banks in a programmable device (e.g., PLD, FPGA, etc.), with each group being separately powered by the user. The disclosed multi-functional I/O buffer may be programmably configured by the user to be, e.g.
