Introduction
The Spartan
®
-II Field-Programmable Gate Array family
gives users high performance, abundant logic resources,
and a rich feature set, all at an exceptionally low price. The
six-member family offers densities ranging from 15,000 to
200,000 system gates, as shown in
Table 1.
System
performance is supported up to 200 MHz. Features include
block RAM (to 56K bits), distributed RAM (to 75,264 bits),
16 selectable I/O standards, and four DLLs. Fast,
predictable interconnect means that successive design
iterations continue to meet timing requirements.
The Spartan-II 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).

serial mode), or written into the FPGA in slave serial, slave
parallel, or Boundary Scan modes.
Spartan-II FPGAs are typically used in high-volume
applications where the versatility of a fast programmable
solution adds benefits. Spartan-II FPGAs are ideal for
shortening product development cycles while offering a
cost-effective solution for high volume production.
Spartan-II FPGAs achieve high-performance, low-cost
operation through advanced architecture and
semiconductor technology. Spartan-II devices provide
system clock rates up to 200 MHz. In addition to the
conventional benefits of high-volume programmable logic
solutions, Spartan-II 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.
General Overview
The Spartan-II 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-II FPGAs are customized by loading configuration
data into internal static memory cells. Unlimited
reprogramming cycles are possible with this approach.
Stored values in these cells determine logic functions and
interconnections implemented in the FPGA. Configuration
data can be read from an external serial PROM (master
