XC4VLX40-11FFG668I: High-Speed Industrial FPGA for Mission-Critical Logic
The XC4VLX40-11FFG668I is a high-performance, industrial-grade member of the Xilinx Virtex®-4 LX family. It is specifically binned for the -11 speed grade, providing the fastest logic switching and tighter timing margins required for high-frequency digital signal processing. Engineered on the 90nm ASMBL™ architecture, this FPGA delivers a robust balance of 41k logic cells and versatile I/O capabilities, all within a ruggedized Industrial Temperature (-40°C to +100°C) envelope.
For hardware engineers, the “11I” combination is the gold standard for applications where timing closure is difficult and the operating environment is unpredictable.
Engineering Core Features
Premium Speed Grade (-11): Provides enhanced frequency headroom, allowing for more complex logic levels between clock edges. This is critical for stabilizing 300MHz+ internal data paths.
Industrial Thermal Resilience: Rated for -40°C to +100°C Tj. Unlike commercial parts, this device maintains its timing specifications across extreme temperature fluctuations, making it essential for outdoor infrastructure and heavy industrial control.
Advanced Memory & DSP Integration: Equipped with 1,728 Kb of Block RAM và 64 dedicated XtremeDSP™ slices. The DSP48 blocks allow for efficient, hard-coded arithmetic acceleration without consuming standard logic gates.
High-Density SelectIO™: The FFG668 package breaks out 448 User I/Os, supporting a vast range of signaling standards (LVDS, HSTL, SSTL). The Flip-Chip (FFG) design ensures low-inductance paths, significantly reducing ground bounce and EMI.
Lead-Free RoHS Compliance: The “FFG” designation ensures the device meets all modern environmental regulations for global distribution without sacrificing thermal performance.

Why Specify the LX40-11I?
1. Precision Timing Under Load
In complex RTL designs, routing congestion often eats into your timing budget. The -11 speed grade provides the necessary slack to ensure your design hits 200MHz-350MHz clock targets even at high logic utilization levels.
2. Thermal Stability for Long-Lifecycle Projects
Industrial systems often face “hot spots” within enclosures. Selecting the Công nghiệp (-I) grade provides an extra 15°C of safety margin over commercial parts, preventing thermal-induced logic errors and extending the Mean Time Between Failures (MTBF) of your end product.
3. Optimized Footprint for Multi-Interface Bridging
The FFG668 package strikes an excellent balance between pin-count and PCB routing complexity. It is large enough to handle wide DDR2 or QDR memory interfaces but compact enough for high-density line cards and modular industrial controllers.
