The XC7VX485T-2FF1761I is a high-performance Field Programmable Gate Array from the AMD Virtex-7 XT family, engineered for bandwidth-intensive and compute-heavy applications. Built on state-of-the-art, high-performance, low-power (HPL), 28 nm, high-k metal gate (HKMG) process technology FPGAkey, this industrial-grade device delivers exceptional logic density, DSP throughput, and serial I/O bandwidth in a rugged 1761-ball flip-chip BGA package. Engineers choose this Xilinx FPGA for 10G–100G networking, radar signal processing, ASIC prototyping, and PCIe-based data-center accelerators.
Key Features and Benefits
The XC7VX485T-2FF1761I offers an unmatched balance of performance-per-watt and system integration. With 1.4 Tb/s of I/O bandwidth, 980K logic cell capacity, and 4.7 TMAC/s DSP FPGAkey at the family level, it provides a fully programmable alternative to ASSPs and ASICs. Its advanced 6-input LUT fabric, hardened PCIe block, and GTX/GTH transceivers make it ideal for designs requiring deterministic latency and massive parallelism.
