Spartan-3AN FPGA Family Description

The Spartan-3AN FPGA family blends nonvolatile technology across a wide variety of densities with the best features of a cutting edge, low cost FPGA. All of the Spartan-3A FPGA family's characteristics are combined with state-of-the-art in-system Flash memory for configuration and nonvolatile data storage. The Extended Spartan-3A family, which also consists of the Spartan-3A FPGAs and the Spartan-3A DSP FPGAs with a higher density, contains the Spartan-3AN FPGAs. For applications requiring limited size, such as blade servers, medical equipment, automobile entertainment, telematics, GPS, and other compact consumer goods, the Spartan-3AN FPGA family excels. System reliability is increased while chip count, PCB traces, and overall size are reduced when FPGA and Flash technology are combined. 
The internal configuration interface of the Spartan-3AN FPGA is entirely self-contained, enhancing design security. The family continues to provide external configuration its full support. The Spartan-3AN FPGA is the first nonvolatile FPGA in the world to provide MultiBoot, which supports two or more configuration files on a single device and enables alternate configurations for field upgrades, test modes, or various system configurations.
