SPARTAN-3 GENERATION FPGAs
Xilinx Spartan -3A FPGA Platform
The World’s Lowest-Cost I/O Optimized FPGAs
™
The Programmable Logic
Challenge of I/O Intensive
Designs
•
Traditional FPGAs are proportionate
between logic and I/O not being cost-
effective for I/O intensive designs
•
System designers need to quickly adapt
to fast-evolving I/O standards
•
High volume consumer applications
require low-cost and robust security
solutions
Xilinx is driving the multiple domain-optimized platforms for highly efficient and
optimal design solutions, instead of forcing inefficient, one-size-fits-all solutions on
significantly varying application requirements.
Spartan-3A Platform Key Features
Standard Low-Cost Features
The Spartan-3A FPGA platform is a full feature platform of five devices with
system gates ranging from 50K to 1.4M gates, and I/Os ranging from 108 to 502
I/Os, with density migration. The Spartan-3A FPGAs also support up to 576 Kbits of
fast-block RAM with byte-write enable, and up to 176 Kbits of distributed RAM.
The Xilinx FPGA Solution
•
The Spartan
™
-3A FPGAs were designed
for applications where I/O count and
capabilities matter more than logic density
•
The Spartan-3A platform delivers up to
502 I/Os with support for industry-leading
26 popular and emerging I/O standards
•
The industry’s first 90nm FPGA electronic
ID - Device DNA serial number provides
a cost-effective, robust mechanism to help
protect against reverse-engineering,
cloning and overbuilding
Additionally, there are built-in multipliers for efficient DSP implementation and
Digital Clock Managers (DCMs) for system level clock management functions.
Advance Features
The advance features in the Spartan-3A platform include unique Device DNA
serial number, support for 26 I/O standards, enhanced Multi-Boot capability
with watchdog timer, dual power management modes, and Dynamic Input
Delay for precise data-to-clock centering. These advance features significantly
help shorten design cycles and lower system cost.
Industry’s first 90nm FPGA Electronic Serial Numbering
Each FPGA includes a permanent unique Device DNA serial number that can be used to
safeguard both hardware and software IP. It is ideal for tracking production serial numbers,
product registrations and system ID. Customers have complete flexibility in implementing
custom algorithms for the security solutions that can significantly deter reverse-engineering,
cloning and overbuilding.

Widest Support for I/O Standards
The Spartan-3A FPGA is especially suitable for display devices supporting both TMDS and
PPDS standards. With support for 26 popular single-ended and differential signaling stan-
dards including TMDS, PPDS, SSTL3 Class I & II, full hot-swap compliance, and pre-engi-
neered interface IP solutions such as PCI, PCI Express, USB, Firewire, CAN, SPI, I2C, etc, the
Spartan-3A platform provides an industry-leading connectivity solution.

Comprehensive Configuration Capabilities
The Spartan-3A platform features enhanced Multi-Boot capability with watchdog timer for
guaranteed “golden” configuration. This enables intelligent recovery from configuration
errors and improves field upgradeability.
Flexible Power-Management Modes
A new Suspend mode provides a very flexible and effective way to preserve power. In this
mode, the power is comparable to quiescent current, and the configuration data as well as
flip-flop and RAM values are maintained. It also includes a fast wake-up mechanism and sys-
tem level synchronization across time domains.
Dynamic Input Delay
Selecting delay-length for both registered and combinatorial inputs allows for precise timing
relationship adjustment between clock and data. Combinatorial input delay can now also be
dynamically changed through the interconnect. Source synchronous designs will significantly
benefit from this feature.
