SPARTAN-3 GENERATION FPGAs
Xilinx Spartan -3AN FPGAs
Non-Volatile Secure FPGAs for Highest System Integration
™
The System Design Dilemma
•
System Designers today face a
common challenge – how to benefit
from inherent security, board-space
savings and ease-of-configuration of
non-volatile FPGAs while still taking
advantage of the extensive features
and high performance available only
in leading SRAM-based FPGAs
The Xilinx Spartan-3AN
Platform Solution
•
The Spartan
™
-3AN platform offers
uncompromised SRAM-based FPGA
with leading-edge Flash technology
•
Based on the industry’s most success-
ful, cost-effective, and production-
proven 90nm technology, the platform
integrates highly advanced on-chip
security features along with the
industry’s largest user Flash
Spartan-3AN Platform Key Features
Delivering the Best of Both Worlds
The non-volatile Spartan-3AN platform provides the best of both worlds – low cost
and extensive features of leading-edge SRAM-based FPGAs with board-space savings
and ease-of-configuration of non-volatile FPGAs. With highly advanced on-chip
security features, the Spartan-3AN platform provides a robust, cost-effective solution
to help prevent reverse-engineering, cloning, and overbuilding. Furthermore,
designers can achieve superior system flexibility with up to 11Mb of integrated
user Flash which can be used for both device configuration as well as a valuable
system resource.
The Complete Low-Cost FPGA Platform
The Spartan-3AN platform is a highly integrated device targeted for the cost-
conscious, high-volume market. It 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, and pin compatible with the Spartan-3A platform.
Spartan-3AN FPGAs support up to 576 Kbits of fast block RAM with byte-write
enable, and up to 176 Kbits of distributed RAM. There are built-in multipliers
for efficient DSP implementation and Digital Clock Managers (DCMs) for system
level clock management functions. Based on production-proven 90nm technology,
Spartan-3AN FPGAs provide exceptional performance while still being extremely
cost-effective.
Industry’s first 90nm FPGA with Electronic Serial Numbering
Each FPGA includes a permanent unique Device DNA serial number and Factory Flash ID.
Designers have complete flexibility in implementing highly customized algorithms for both
authentication, as well as non-authentication responses such as limited-functionality,
time-bomb, and self-destruct. This can significantly deter reverse-engineering, cloning,
and overbuilding.

Industry’s Largest On-Chip User Flash
The new Spartan-3AN platform boasts the industry’s largest on-chip user flash with a
capacity of up to 11Mb. It provides simple and secure embedded application storage,
while also enabling advanced real-time control with fine-grained protection, lockdown
and erase features.
Widest Support for I/O Standards
The Spartan-3AN FPGA is especially suitable for display devices supporting both TMDS and
PPDS standards. With support for 26 popular single-ended and differential signaling standards
including LVDS, RSDS, SSTL3 Class I & II, full hot-swap compliance, and pre-engineered
interface IP solutions such as PCI, PCI Express, USB, Firewire, CAN, SPI, and I2C, the
Spartan-3AN platform provides an industry-leading connectivity solution.

Flexible Power-Management Modes
The “Suspend” Mode in Spartan-3AN FPGAs provides a very flexible and effective way to
preserve power. In this mode, the total FPGA power is reduced by more than 40%. The
configuration data as well as flip-flop and RAM values are also maintained. In addition, it
includes a fast wake-up mechanism and system level synchronization across time domains.
