Additional Details:

The XC3164-4PC84C features a matrix of Configurable Logic Blocks (CLBs), surrounded by programmable Input/Output Blocks (IOBs). The CLBs can be configured to implement a wide range of combinational and sequential logic functions. The IOBs provide programmable input and output capabilities, including support for different voltage levels and drive strengths. The programmable interconnect matrix allows for flexible routing of signals between the CLBs and IOBs. The device is configured by loading configuration data into its internal SRAM. This allows the device to be reconfigured as many times as needed. The '4' in the part number indicates the speed grade.
