Description
The XC4000 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 XC4000 family provides a regular, flexible, program-
mable architecture of Configurable Logic Blocks (CLBs),
interconnected by a powerful hierarchy of versatile routing
resources, and surrounded by a perimeter of program-
mable Input/Output Blocks (IOBs).
XC4000 devices have generous routing resources to ac-
commodate the most complex interconnect patterns. They
are customized by loading configuration data into the inter-
nal 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 modes).
The XC4000 family is supported by powerful and sophisti-
cated 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.
Since Xilinx FPGAs can be reprogrammed an unlimited
number of times, they can be used in innovative designs
where hardware is changed dynamically, or where hard-
ware must be adapted to different user applications. FPGAs
are ideal for shortening the design and development cycle,
but they also offer a cost-effective solution for production
rates well beyond 1000 systems per month.
For a detailed description of the device features, architec-
ture, configuration methods and pin descriptions, see
pages 2-9 through 2-45.
