XC5VFX70T-2FFG1136C – Xilinx Virtex-5 FXT FPGA
The XC5VFX70T-2FFG1136C is a mid-density FPGA from the Xilinx Virtex-5 FXT family, designed for systems that require embedded processing capability, high-speed serial connectivity, and reliable logic performance within a single device. At LXB Semicon, this part is commonly supplied for communication and embedded platforms operating in controlled environments, as well as for ongoing support of established Virtex-5–based designs.
Logic Resources and Embedded Processing
The XC5VFX70T provides approximately 70K logic cells, making it suitable for protocol handling, multi-interface control logic, and custom hardware functions. As an FXT-family device, it integrates dual PowerPC® 440 processors, allowing designers to run system control, management software, and real-time tasks directly inside the FPGA fabric.
The -2 speed grade offers improved timing performance compared to lower speed grades, supporting higher internal clock frequencies and tighter timing margins for designs with moderate to demanding performance requirements.
High-Speed Serial Connectivity
This device includes RocketIO™ GTX transceivers, enabling direct support for high-speed serial standards such as PCI Express, Serial RapidIO, Gigabit Ethernet backplanes, and proprietary point-to-point links. By integrating these interfaces on-chip, system designers can reduce external components and simplify high-speed PCB layouts.
On-Chip Memory and System Integration
Integrated Block RAM resources support on-chip buffering, data queues, and local memory for the embedded processors. This helps reduce external memory access, improves latency control, and contributes to predictable system behavior in real-time applications.
The Virtex-5 FXT platform is supported by a mature Xilinx toolchain and a broad ecosystem of proven IP cores, which remains valuable for long-life products and maintenance-focused projects.
Package and Commercial Temperature Grade
The FFG1136 flip-chip BGA package provides a high pin count, enabling flexible I/O assignment and support for interface-dense board designs.
The commercial temperature grade (C) is intended for controlled operating environments such as indoor communication equipment, laboratory systems, and enterprise platforms.
Typical Applications
The XC5VFX70T-2FFG1136C is commonly used in:
-
Telecommunications and networking equipment
-
Embedded processing platforms with hardware–software co-design
-
Test and measurement systems
-
High-speed data acquisition and interface cards
-
Legacy system upgrades and long-term production programs
Although Virtex-5 is a mature FPGA family, the XC5VFX70T remains relevant due to its balanced logic capacity, integrated CPU architecture, and proven field reliability. For engineers maintaining existing FXT-based designs, it offers a stable, low-risk solution with predictable performance.
