Altera FPGA EP2C5Q208C8N, Cyclone II 4608 Cells, 4608 Blocks, 208-Pin PQFP

An FPGA is a semiconductor device consisting of a matrix of Configurable Logic Blocks (CLBs) connected through programmable interconnects. The user determines these interconnections by programming SRAM. A CLB can be simple (AND, OR gates, etc) or complex (a block of RAM). The FPGA allows changes to be made to a design even after the device is soldered into a PCB.
