XC7VX1140T-2FLG1926C Overview
The XC7VX1140T-2FLG1926C is a high-performance Virtex-7 XT FPGA from Xilinx (now AMD), engineered for the most demanding networking, signal processing, and ASIC prototyping workloads. As the largest device in the Virtex-7 XT family, it delivers 1,139,200 logic cells, 96 GTH multi-gigabit transceivers, and 1.4 Tb/s of total I/O bandwidth in a single 1926-pin flip-chip BGA package.
Built on TSMC’s 28 nm HPL high-k metal gate process and using Xilinx’s stacked silicon interconnect (SSI) technology, the XC7VX1140T-2FLG1926C combines four super logic regions (SLRs) on a passive silicon interposer to deliver capacity that no monolithic die could match — while consuming up to 50% less power than 40 nm predecessors. It is a flagship part among Xilinx FPGA devices for 400G networking, 100G OTN, radar, software-defined radio, and high-frequency trading platforms.
