Specifications
The XC5VFX70T-1FF1136C belongs to the Virtex-5 FXT family from Xilinx (now part of AMD). It’s a mid-density FPGA that combines programmable logic with embedded processing and high-speed serial connectivity — a solid choice for communication, industrial, and embedded computing designs that still rely on proven 65nm FPGA platforms.
Key Technical Highlights
FPGA Family: Virtex-5 FXT (65nm process)
Package: FF1136 (Flip-Chip BGA, 1136 pins)
Speed Grade: -1
Temperature Grade: Commercial (0°C to +85°C)
Embedded Processor: Dual PowerPC 440 (depending on configuration)
High-Speed Serial: RocketIO GTX transceivers (multi-gigabit capability)
Logic Resources: Balanced LUT, Block RAM, and DSP48E slices
I/O Support: Wide voltage compatibility for flexible board-level design
Compared to pure logic variants (like LX series), the FXT architecture adds system-level integration. You get embedded processing plus high-speed serial connectivity in one device. That means fewer external components, tighter timing control, and simplified PCB routing in dense designs.
The FF1136 package is not small — but that’s intentional. It supports high I/O count and serious signal routing capability. If you’re working with complex backplanes or multi-lane serial links, the pin density is actually an advantage.
Procurement & Lifecycle Considerations
Many projects using this device are in the sustainment phase. If you’re repairing telecom boards, extending industrial equipment life, or supporting military platforms, device authenticity and traceability matter more than marketing claims.
