XC4000, XC4000A, XC4000H Logic Cell Array Families
Product Description
Features
Description
The XC4000 families of Field-Programmable Gate Arrays (FPGAs) provide the benefits of custom CMOS VLSI, while avoiding the initial cost, time delay, and inherent risk of a conventional masked gate array. The XC4000 families provide a regular, flexible, programmable architecture of Configurable Logic Blocks (CLBs), interconnected by a powerful hierarchy of versatile routing resources, and surrounded by a perimeter of programmable Input/Output Blocks (IOBs). XC4000-family devices have generous routing resources to accommodate the most complex interconnect patterns. XC4000A devices have reduced sets of routing resources, sufficient for their smaller size.
