The XC7VH580T-2FLG1931C is a high-end Virtex-7 HT-series Xilinx FPGA engineered for applications that demand massive I/O bandwidth, ultra-fast serial transceivers, and large logic capacity in one device. Built on TSMC’s 28 nm HKMG HPL process and housed in a 1931-ball FLG flip-chip BGA, the XC7VH580T-2FLG1931C targets 100G/400G optical networking, ASIC prototyping, high-frequency trading, SIGINT/radar, and advanced test & measurement systems.
What Is the XC7VH580T-2FLG1931C?
The XC7VH580T-2FLG1931C is a 3D heterogeneous SSI (Stacked Silicon Interconnect) device. It combines two Virtex-7 FPGA dies with a dedicated GTZ transceiver die on a passive silicon interposer. As a result, it delivers 580,480 logic cells, up to 1.4 Tb/s of I/O bandwidth, and roughly 4.7 TMAC/s of DSP performance, while consuming up to 50% less static power than the previous 40 nm Virtex-6 generation. The “-2” speed grade and “C” commercial temperature rating make this part well suited for high-volume telecom and datacenter line cards.

Key Features and Architecture
The XC7VH580T-2FLG1931C’s GTZ transceivers operate up to 28.05 Gb/s, enabling single-chip CFP2/CFP4 100G optical implementations and dual 100G aggregation. GTH lanes support 10GBASE-KR-compliant backplane links, while two integrated PCIe Gen3 ×8 hard blocks shrink board footprint and accelerate host data movement. Each DSP48E1 slice includes a 25×18 multiplier, pre-adder, and 48-bit accumulator—ideal for FIR filtering, FFTs, matrix math, and digital pre-distortion.
Typical Applications
- 100G / 400G optical transport (OTN, Ethernet)
- Wireless infrastructure and 5G fronthaul/backhaul
- ASIC prototyping and emulation platforms
- High-performance test & measurement instruments
- Software-defined radio, radar, and electronic warfare systems
