XC4000E and XC4000X Series Field Programmable Gate Arrays

Note: All functionality in low-voltage families is the same as
in the corresponding 5-Volt family, except where numerical
references are made to timing or power.
Description
XC4000 Series devices are implemented with 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). They have
generous routing resources to accommodate the most
complex interconnect patterns.
The devices are customized by loading configuration data
into internal memory cells. The FPGA can either actively
read its configuration data from an external serial or
byte-parallel PROM (master modes), or the configuration
data can be written into the FPGA from an external device
(slave and peripheral modes).
XC4000 Series FPGAs are supported by powerful and
sophisticated software, covering every aspect of design
from schematic or behavioral entry, floor planning, simula-
tion, automatic block placement and routing of intercon-
nects, to the creation, downloading, and readback of the
configuration bit stream.
Because Xilinx FPGAs can be reprogrammed an unlimited
number of times, they can be used in innovative designs

Typical
where hardware is changed dynamically, or where hard-
ware must be adapted to different user applications.
FPGAs are ideal for shortening design and development
cycles, and also offer a cost-effective solution for produc-
tion rates well beyond 5,000 systems per month.

Taking Advantage of Re-configuration
FPGA devices can be re-configured to change logic func-
tion while resident in the system. This capability gives the
system designer a new degree of freedom not available
with any other type of logic.
Hardware can be changed as easily as software. Design
updates or modifications are easy, and can be made to
products already in the field. An FPGA can even be re-con-
figured dynamically to perform different functions at differ-
ent times.
Re-configurable logic can be used to implement system
self-diagnostics, create systems capable of being re-con-
figured for different environments or operations, or imple-
ment multi-purpose hardware for a given application. As an
added benefit, using re-configurable FPGA devices simpli-
fies hardware design and debugging and shortens product
time-to-market.
