XC3000 Series Field Programmable Gate Arrays
7-4
November 9, 1998 (Version 3.1)
Introduction
XC3000-Series Field Programmable Gate Arrays (FPGAs)
provide a group of high-performance, high-density, digital
integrated circuits. Their regular, extendable, flexible,
user-programmable array architecture is composed of a
configuration program store plus three types of config-
urable elements: a perimeter of I/O Blocks (IOBs), a core
array of Configurable Logic Bocks (CLBs) and resources
for interconnection. The general structure of an FPGA is
shown in Figure 2. The development system provides
schematic capture and auto place-and-route for design
entry. Logic and timing simulation, and in-circuit emulation
are available as design verification alternatives. The design
editor is used for interactive design optimization, and to
compile the data pattern that represents the configuration
program.
The FPGA user logic functions and interconnections are
determined by the configuration program data stored in
internal static memory cells. The program can be loaded in
any of several modes to accommodate various system
requirements. The program data resides externally in an
EEPROM, EPROM or ROM on the application circuit
board, or on a floppy disk or hard disk. On-chip initialization
logic provides for optional automatic loading of program
data at power-up. The companion XC17XX Serial Configu-
ration PROMs provide a very simple serial configuration
program storage in a one-time programmable package.
The XC3000 Field Programmable Gate Array families pro-
vide a variety of logic capacities, package styles, tempera-
ture ranges and speed grades.
XC3000 Series Overview
There are now four distinct family groupings within the
XC3000 Series of FPGA devices:
XC3000A Family
XC3000L Family
XC3100A Family
XC3100L Family
All four families share a common architecture, develop-
ment software, design and programming methodology, and
also common package pin-outs. An extensive Product
Description covers these common aspects.
Detailed
parametric
information
for
the
XC3000A,
XC3000L, XC3100A, and XC3100L product families is then
provided. (The XC3000 and XC3100 families are not rec-
ommended for new designs.)
Here is a simple overview of those XC3000 products cur-
rently emphasized:
XC3000A Family — The XC3000A is an enhanced
version of the basic XC3000 family, featuring additional
interconnect resources and other user-friendly
enhancements.
XC3000L Family — The XC3000L is identical in
architecture and features to the XC3000A family, but
operates at a nominal supply voltage of 3.3 V. The
XC3000L is the right solution for battery-operated and
low-power applications.
XC3100A Family — The XC3100A is a
performance-optimized relative of the XC3000A family.
While both families are bitstream and footprint
compatible, the XC3100A family extends toggle rates to
370 MHz and in-system performance to over 80 MHz.
The XC3100A family also offers one additional array
size, the XC3195A.
XC3100L Family — The XC3100L is identical in
architectures and features to the XC3100A family, but
operates at a nominal supply voltage of 3.3V.
Figure 1 illustrates the relationships between the families.
Compared to the original XC3000 family, XC3000A offers
additional functionality and increased speed. The XC3000L
family offers the same additional functionality, but reduced
speed due to its lower supply voltage of 3.3 V. The
XC3100A family offers substantially higher speed and
higher density with the XC3195A.
New XC3000 Series Compared to Original
XC3000 Family
For readers already familiar with the original XC3000 family
of FPGAs, the major new features in the XC3000A,
XC3000L, XC3100A, and XC3100L families are listed in
this section.
All of these new families are upward-compatible extensions
of the original XC3000 FPGA architecture. Any bitstream
used to configure an XC3000 device will configure the cor-
responding XC3000A, XC3000L, XC3100A, or XC3100L
device exactly the same way.
The XC3100A and XC3100L FPGA architectures are
upward-compatible extensions of the XC3000A and
XC3000L architectures. Any bitstream used to configure an
XC3000A or XC3000L device will configure the corre-
sponding XC3100A or XC3100L device exactly the same
way.
