The XC4VLX40-11FFG1148I is a Virtex®-4 LX field programmable gate array (FPGA) offered by AMD. It delivers a high count of programmable logic and on-chip memory with extensive I/O in a compact 1148-ball FCBGA package for surface-mount applications.

With 41,472 logic elements, approximately 1.77 Mbits of embedded memory, and 640 I/O pins, this device targets designs that require dense logic integration, significant on-chip storage, and large interfacing capability within an industrial-temperature range.

Key Features

• Core Logic  41,472 logic elements provide substantial fabric capacity for implementing complex digital functions and custom logic.
• Configurable Logic Blocks  4,608 configurable logic blocks (CLBs) for structured logic partitioning and design scalability.
• Embedded Memory  Approximately 1.77 Mbits of on-chip RAM to support buffering, lookup tables, and intermediate data storage without external memory.
• I/O Density  640 user I/O pins enable wide bus interfaces, multiple peripheral connections, and extensive external signaling.
• Package & Mounting  1148-BBGA package (supplier package: 1148-FCPBGA, 35×35 mm) designed for surface-mount assembly in space-constrained boards.
• Power Supply  Operates from a core supply range of 1.14 V to 1.26 V to match system power rail planning.
• Industrial Temperature Grade  Rated for operation from −40°C to 100°C, suitable for industrial-environment deployments.
• Regulatory  RoHS compliant for materials and environmental requirements.

Typical Applications

• High-density digital processing  Use the device’s 41,472 logic elements and embedded RAM to implement complex signal processing, protocol handling, or custom compute blocks on-chip.
• Large I/O interface systems  With 640 I/O pins, integrate multiple parallel buses, sensor arrays, or wide memory interfaces without external expanders.
• Industrial control and automation  Industrial temperature rating and robust packaging make it suitable for control logic, real-time sequencing, and I/O aggregation in industrial equipment.

Unique Advantages

• High integration density: Consolidate logic and memory on-chip with 41,472 logic elements and ~1.77 Mbits of RAM to reduce external component count.
