Spartan-IIE FPGA Family: Introduction and Ordering Information
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
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.

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.
