The XC7VX1140T-1FLG1926I is a high-performance Xilinx Virtex-7 XT family FPGA built on 28 nm HKMG process technology. It delivers 1,139,200 logic cells, 1.4 Tb/s of I/O bandwidth, and 4.7 TMAC/s DSP performance — all in an industrial-grade FCBGA-1926 package.
Overview of the XC7VX1140T-1FLG1926I
Designed for the most bandwidth-hungry applications, the XC7VX1140T-1FLG1926I belongs to the Virtex-7 XT series. It targets wired and wireless communications, high-speed signal processing, ASIC prototyping, medical imaging, and aerospace systems. Thanks to its industrial temperature grade (–40 °C to +100 °C junction), this device performs reliably in demanding deployment environments.
Moreover, the chip is manufactured using 28 nm high-k metal gate (HKMG) process technology, which cuts power consumption by roughly 50% versus the previous Virtex-6 generation. As a result, designers can scale up logic capacity without breaking the power budget. For the broader product family and pricing, browse our complete Xilinx FPGA catalog.
