The XC7VX485T-1FFG1761C is a high-performance Field Programmable Gate Array from AMD’s Virtex-7 XT family, built on TSMC’s 28 nm HKMG (High-K Metal Gate) process. With 485,760 logic cells, 56 GTX multi-gigabit transceivers, and 700 user I/Os packed into a 1761-ball flip-chip BGA, the XC7VX485T-1FFG1761C is engineered for bandwidth-intensive designs in wired communications, radar, ASIC prototyping, and data-center acceleration.
Why Choose the XC7VX485T-1FFG1761C?
Virtex-7 XT devices are optimized for transceiver-heavy workloads, and the XC7VX485T-1FFG1761C delivers that balance of logic density, DSP throughput, and serial I/O that most -485T designs need. The “-1” speed grade and commercial temperature rating (0 °C to 85 °C) make it a cost-effective pick for lab, industrial, and production hardware where you still want the full pin-out of the 1761 package for maximum I/O and transceiver access.
