A class of fpgas with the lowest cost in the industry;The latter is mainly for high-end applications and belongs to the top products in the industry.The differences between the two series are limited only to the size of the chip and the dedicated modules, both using advanced 0.13, 90 and even 65 manufacturing processes, with the same superior quality. 1. Spartan FPGA The Spartan family is suitable for common industrial, commercial and other fields. The mainstream chips include: spartan-2, spartan-2e, spartan-3, spartan-3a, spartan-3e and the latest spartan-6.Spartan-2 can reach up to 200,000 system doors, spartan-2e can reach up to 600,000 system doors, and spartan-3 can reach up to 5 million doors. The spartan-3a and spartan-3e not only have a larger number of system doors, but also enhance a large number of built-in special multiplier and special block RAM resources, enabling the realization of complex digital signal processing and programmable systems on chip.
