Introduction
The Spartan
®
-3 family of Field-Programmable Gate Arrays
is specifically designed to meet the needs of high volume,
cost-sensitive consumer electronic applications. The
eight-member family offers densities ranging from 50,000 to
five million system gates, as shown in
Table 1.
The Spartan-3 family builds on the success of the earlier
Spartan-IIE family by increasing the amount of logic
resources, the capacity of internal RAM, the total number of
I/Os, and the overall level of performance as well as by
improving clock management functions. Numerous
enhancements derive from the Virtex
®
-II platform technol-
ogy. These Spartan-3 FPGA enhancements, combined with
advanced process technology, deliver more functionality
and bandwidth per dollar than was previously possible, set-
ting new standards in the programmable logic industry.
Because of their exceptionally low cost, Spartan-3 FPGAs
are ideally suited to a wide range of consumer electronics
applications, including broadband access, home network-
ing, display/projection and digital television equipment.
The Spartan-3 family is a superior alternative to mask pro-
grammed ASICs. FPGAs avoid the high initial cost, the
lengthy development cycles, and the inherent inflexibility of
conventional ASICs. Also, FPGA programmability permits
design upgrades in the field with no hardware replacement
necessary, an impossibility with ASICs.
The Spartan-3 FPGAs are the first platform among several
within the
Spartan-3 Generation FPGAs.

Spartan-3 FPGA Family: Introduction and Ordering Information
R
Architectural Overview
The Spartan-3 family architecture consists of five funda-
mental programmable functional elements:
•
Configurable Logic Blocks (CLBs) contain RAM-based
Look-Up Tables (LUTs) to implement logic and storage
elements that can be used as flip-flops or latches.
CLBs can be programmed to perform a wide variety of
logical functions as well as to store data.
Input/Output Blocks (IOBs) control the flow of data
between the I/O pins and the internal logic of the
device. Each IOB supports bidirectional data flow plus
3-state operation. Twenty-six different signal standards,
including eight high-performance differential standards,
are available as shown in
Table 2.
Double Data-Rate
(DDR) registers are included. The Digitally Controlled
Impedance (DCI) feature provides automatic on-chip
terminations, simplifying board designs.
Block RAM provides data storage in the form of 18-Kbit
dual-port blocks.
Multiplier blocks accept two 18-bit binary numbers as
inputs and calculate the product.
•
Digital Clock Manager (DCM) blocks provide
self-calibrating, fully digital solutions for distributing,
delaying, multiplying, dividing, and phase shifting clock
signals.
•
These elements are organized as shown in
Figure 1.
A ring
of IOBs surrounds a regular array of CLBs. The XC3S50
has a single column of block RAM embedded in the array.
Those devices ranging from the XC3S200 to the XC3S2000
have two columns of block RAM. The XC3S4000 and
XC3S5000 devices have four RAM columns. Each column
is made up of several 18-Kbit RAM blocks; each block is
associated with a dedicated multiplier. The DCMs are posi-
tioned at the ends of the outer block RAM columns.
The Spartan-3 family features a rich network of traces and
switches that interconnect all five functional elements,
transmitting signals among them. Each functional element
has an associated switch matrix that permits multiple con-
nections to the routing.

devices are shown with dashed lines. The XC3S50 has only the block RAM
column on the far left.

Spartan-3 FPGA Family: Introduction and Ordering Information
The recommended memory for storing the configuration
data is the low-cost Xilinx Platform Flash PROM family,
which includes the XCF00S PROMs for serial configuration
and the higher density XCF00P PROMs for parallel or serial
configuration.
Configuration
Spartan-3 FPGAs are programmed by loading configuration
data into robust, reprogrammable, static CMOS configura-
tion latches (CCLs) that collectively control all functional
elements and routing resources. Before powering on the
FPGA, configuration data is stored externally in a PROM or
some other nonvolatile medium either on or off the board.
After applying power, the configuration data is written to the
FPGA using any of five different modes: Master Parallel,
Slave Parallel, Master Serial, Slave Serial, and Boundary
Scan (JTAG). The Master and Slave Parallel modes use an
8-bit wide SelectMAP port.

I/O Capabilities
The SelectIO feature of Spartan-3 devices supports 18 sin-
gle-ended standards and 8 differential standards as listed in
Table 2.
Many standards support the DCI feature, which
uses integrated terminations to eliminate unwanted signal
reflections..
