spartan-3a xilinx device dna

The company xilinx announced the release of platform spartan-3AN, which, if we believe to producer, is the foremost solution in the region of the energy-independent programmed gate arrays (Field programmable gate array, FPGA). Built during the checked by time 90 nm generation Spartan- 3, new product unites productivity and functionality, characteristic for SRAM, with the reliability, characteristic of energy-independent flash- memory, in one chip. Developer emphasizes that the platform spartan-3AN is optimized for applications, where are imposed high demands on security and to the degree of integration. It is substantial in the number of cycles rerecording of the built-in flash- memory spartan-3AN, to thousand times, exceeds the products of nearest competitors.
The models spartan-3AN include the means, at basis of which lies the technology xilinx device DNA, that impede the technical analysis (so-called reversible Engineering), cloning and unauthorized modification of product. In particular, the chips spartan-3AN have the factory and user identifiers flash- memory. Unique factory identifier with the length 64 bytes can be considered from instrument and used in algorithms identification. User identifier, also with the length 64 bytes, is once programmed and serves for storing result of identification, series numbers, versions or user constants, which under no conditions must not change in the process of operating equipment.

Declared storage time of information in flash- memory of new FPGA is 20 years, the number of cycles rerecording is 100000. Memory capacity, can be regulated under the needs of user, it depends on model, and it reaches 11 mb. Among other special features of new microcircuits the producer notes the presence of two regimes energy-economy, simplicity of configuration and low cost.

The platform spartan-3AN includes five models. Accessible modifications cover with large quantity of configurations: a quantity of gates lies within the limits from 50 thousand to 1,4 mln., the volume of operational memory can reach 576 KB, built-in flash- memories 16 mb., while a quantity of lines of the input-output is 502. The support of 26 popular protocols input-output is realized. All instruments compatible on the arrangement of conclusions with the models of family spartan-3A, and their mass production is planned for the third quarter.
