Spartan-IIE 1.8V FPGA Family: Introduction and Ordering Information
2
1-800-255-7778Preliminary Product SpecificationR
General Overview
The Spartan-IIE family of FPGAs have a regular, flexible,
programmable architecture of Configurable Logic Blocks
(CLBs), surrounded by a perimeter of programmable
Input/Output Blocks (IOBs). There are four Delay-Locked
Loops (DLLs), one at each corner of the die. Two columns
of block RAM lie on opposite sides of the die, between the
CLBs and the IOB columns. These functional elements are
interconnected by a powerful hierarchy of versatile routing
channels (see
Figure 1
).
Spartan-IIE FPGAs are customized by loading configura-
tion data into internal static memory cells. Unlimited repro-
gramming cycles are possible with this approach. Stored
values in these cells determine logic functions and intercon-
nections implemented in the FPGA. Configuration data can
be read from an external serial PROM (master serial mode),
or written into the FPGA in slave serial, slave parallel, or
Boundary Scan modes. The Xilinx XC17S00A PROM family
is recommended for serial configuration of Spartan-IIE
FPGAs. The XC18V00 reprogrammable PROM family is
recommended for parallel or serial configuration.
Spartan-IIE FPGAs are typically used in high-volume appli-
cations where the versatility of a fast programmable solution
adds benefits. Spartan-IIE FPGAs are ideal for shortening
product development cycles while offering a cost-effective
solution for high volume production.
Spartan-IIE FPGAs achieve high-performance, low-cost
operation through advanced architecture and semiconduc-
tor technology. Spartan-IIE devices provide system clock
rates beyond 200 MHz. Spartan-IIE FPGAs offer the most
cost-effective solution while maintaining leading edge per-
formance. In addition to the conventional benefits of
high-volume programmable logic solutions, Spartan-IIE
FPGAs also offer on-chip synchronous single-port and
dual-port RAM (block and distributed form), DLL clock driv-
ers, programmable set and reset on all flip-flops, fast carry
logic, and many other features.
