The XC7VX485T-1FFG1157I is a high-performance, industrial-grade Field Programmable Gate Array from the AMD Xilinx Virtex-7 XT family. Built on 28nm HKMG process technology, this device delivers an exceptional mix of logic density, DSP throughput, and high-speed serial I/O — making it a proven choice for networking, radar, ASIC prototyping, and data-center acceleration designs. As a widely stocked Xilinx FPGA, the XC7VX485T-1FFG1157I remains a go-to device for engineers who need reliability and raw bandwidth in one package.
Key Features of the XC7VX485T-1FFG1157I
The XC7VX485T-1FFG1157I packs 485,760 logic cells, 2,800 DSP48E1 slices, and 37,080 Kbit of block RAM into a compact 1157-ball FCBGA package. Furthermore, it provides up to 600 user I/O pins and integrates hardened PCIe Gen2 x8 blocks, along with multiple GTX/GTH transceivers for high-speed serial links up to 13.1 Gb/s.
Because the device uses speed grade -1 and industrial temperature grade (-40°C to +100°C TJ), it performs reliably in harsh environments — factory automation, aerospace, test & measurement, and defense systems included.
