Description :

The XC3S400-4FGG456C represents a capable member of the Spartan-3 FPGA series, built on 90nm process technology. This FPGA features a comprehensive programmable logic architecture with 8,064 logic cells, 288 Kbits of dedicated block RAM, and 56 Kbits of distributed RAM, providing ample resources for complex state machines, data processing pipelines, and embedded memory applications. Operating at a core voltage of 1.2V with commercial temperature range support (0°C to +85°C), this FPGA offers excellent power efficiency for embedded systems. The -4 speed grade ensures reliable timing closure for designs requiring up to 280 MHz performance. As a true FPGA, it provides complete reconfigurability, allowing designers to implement and modify digital circuits through programming rather than fixed hardware design.
