The XC4000E family of Field-Programmable Gate Arrays

(FPGAs) provides the benefits of custom CMOS VLSI,

while avoiding the initial cost, time delay, and inherent risk

of a conventional masked gate array.

The XC4000E family provides a regular, flexible, pro-

grammable architecture of Configurable Logic Blocks

(CLBs), interconnected by a powerful hierarchy of versa-

tile routing resources, and surrounded by a perimeter of

programmable Input/Output Blocks (IOBs).

XC4000E devices have generous routing resources to

accommodate the most complex interconnect patterns.

They are customized by loading configuration data into

the internal memory cells. The FPGA can either actively

read its configuration data out of external serial or byte-

parallel PROM (master modes), or the configuration data

can be written into the FPGA (slave and peripheral


The XC4000E family is supported by powerful and sophis-

ticated software, covering every aspect of design: from

schematic entry, to simulation, to automatic block place-

ment and routing of interconnects, and finally the creation

of the configuration bit stream.

FPGAs are ideal for shortening the design and develop-

ment cycle, but they also offer a cost-effective solution for

production rates well beyond 1,000 systems per month.

The XC4000E family is a superset of the popular XC4000
