DS077-1 (v2.3) June 18, 2008
Introduction
The Spartan
®
-IIE Field-Programmable Gate Array family
gives users high performance, abundant logic resources,
and a rich feature set, all at an exceptionally low price. The
seven-member family offers densities ranging from 50,000
to 600,000 system gates, as shown in
Table 1.
System per-
formance is supported beyond 200 MHz.
Features include block RAM (to 288K bits), distributed RAM
(to 221,184 bits), 19 selectable I/O standards, and four
DLLs (Delay-Locked Loops). Fast, predictable interconnect
means that successive design iterations continue to meet
timing requirements.
The Spartan-IIE family is a superior alternative to
mask-programmed ASICs. The FPGA avoids the initial cost,
lengthy development cycles, and inherent risk of
conventional ASICs. Also, FPGA programmability permits
design upgrades in the field with no hardware replacement
necessary (impossible with ASICs).

Spartan-IIE FPGA Family: Introduction and Ordering Information
R
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. The XC2S400E has four col-
umns and the XC2S600E has six columns of block RAM.
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. Xilinx offers multiple types of
low-cost configuration solutions including the Platform
Flash in-system programmable configuration PROMs.
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.
DLL
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. In addition to the conventional ben-
efits of high-volume programmable logic solutions, Spar-
tan-IIE FPGAs also offer on-chip synchronous single-port
and dual-port RAM (block and distributed form), DLL clock
drivers, programmable set and reset on all flip-flops, fast
carry logic, and many other features.
