A '''field-programmable gate array''' ('''FPGA''') is a type of configurable [[integrated circuit]] that can be repeatedly programmed after manufacturing. FPGAs are a subset of logic devices referred to as [[programmable logic devices]] (PLDs). They consist of ana grid-connected array of [[programmable logic device|programmable]] [[logic block|logic blocks]] with a connecting grid, that can be configured "in the field" to interconnect with other logic blocks to perform various digital functions. FPGAs are often used in limited (low) quantity production of custom-made products, and in research and development, where the higher cost of individual FPGAs is not as important, and where creating and manufacturing a custom circuit would not be feasible. Other applications for FPGAs include the telecommunications, automotive, aerospace, and industrial sectors, which benefit from their flexibility, high signal processing speed, and parallel processing abilities.

A FPGA configuration is generally written using a [[hardware description language]] (HDL) e.g. [[VHDL]], similar to the ones used for [[application-specific integrated circuit]]s (ASICs). [[Circuit diagram|Circuit diagrams]] were formerly used to write the configuration.
