XC5VFX70T-1FFG1136C – Xilinx Virtex-5 FXT FPGA
The XC5VFX70T-1FFG1136C is a mid-density FPGA from the Xilinx Virtex-5 FXT family, designed for systems that require embedded processing, high-speed serial interfaces, and stable logic performance in a single device. At LXB Semicon, this part is typically supplied for customers maintaining existing Virtex-5 platforms or deploying communication and embedded systems in controlled environments.
Logic Resources and Embedded Processing
The XC5VFX70T provides approximately 70K logic cells, offering sufficient capacity for protocol processing, multi-interface control logic, and custom hardware functions. As part of the FXT family, it integrates dual PowerPC® 440 processors, allowing designers to implement system control, management tasks, and real-time software functions directly inside the FPGA fabric.
The -1 speed grade emphasizes predictable and well-characterized timing behavior, making it suitable for designs that prioritize reliability and deterministic operation over maximum clock speed.
High-Speed Serial Connectivity
This device includes RocketIO™ GTX transceivers, enabling direct implementation of high-speed serial standards such as PCI Express, Serial RapidIO, Gigabit Ethernet backplanes, and proprietary point-to-point links. Integrating the serial interfaces on-chip helps reduce external components and simplifies high-speed PCB design.
On-Chip Memory and System Integration
With integrated Block RAM, the XC5VFX70T supports on-chip buffering, data queues, and local memory for the embedded processors. This reduces external memory access, improves latency control, and contributes to consistent system behavior in real-time applications.
The Virtex-5 FXT platform benefits from a mature Xilinx development environment and a broad ecosystem of proven IP cores, which is particularly valuable for long-life products and system maintenance projects.
Package and Commercial Temperature Grade
The FFG1136 flip-chip BGA package provides a high pin count, supporting flexible I/O assignment and interface-dense board designs.
The commercial temperature grade (C) is intended for controlled operating environments such as indoor communication equipment, lab systems, and enterprise platforms.
Typical Applications
The XC5VFX70T-1FFG1136C 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 the Virtex-5 family is a mature generation, the XC5VFX70T remains a practical choice due to its balanced logic capacity, integrated CPU architecture, and proven field reliability. For engineers supporting existing FXT-based designs, it offers a stable and low-risk solution with predictable performance.
