XC4VSX55-10FF1148C

The XC4VSX55-10FF1148C is a Virtex-4 SX Field Programmable Gate Array (FPGA) from AMD, built for high-density, configurable logic applications. It combines a large logic fabric with substantial on-chip memory and a high I/O count to support complex, custom digital designs that require flexible hardware acceleration and extensive interfacing.

With 6,144 CLBs and 55,296 logic elements, approximately 5.9 Mbits of embedded memory, and 640 I/O pins in a 1148-BBGA package, this commercial-grade FPGA targets designs that demand high integration and configurable system-level functionality within a 0 °C to 85 °C operating range.

Key Features

• Core Logic  6,144 configurable logic blocks (CLBs) delivering 55,296 logic elements for implementing complex programmable logic and custom datapaths.
• Embedded Memory  Approximately 5.9 Mbits of on-chip RAM to support large buffers, FIFOs, and distributed memory needs without external RAM.
• High I/O Density  640 user I/O pins to accommodate extensive sensor, peripheral, and bus interfacing in a single device.
• Power Supply  Operates from a core voltage range of 1.14 V to 1.26 V, enabling predictable power design and voltage planning for the FPGA core.
• Package  1148-BBGA (FCBGA) package, supplier package 1148-FCPBGA (35×35), suitable for surface-mount assembly in compact boards.
• Commercial Temperature Grade  Rated for operation from 0 °C to 85 °C for standard commercial applications.
• Regulatory  RoHS compliant for reduced hazardous substances in manufacturing.

Typical Applications

• High-density I/O systems  Use the 640 I/O pins to consolidate multiple parallel interfaces, front-end connectors, or extensive sensor arrays into a single programmable device.
• Embedded memory-centric designs  Leverage approximately 5.9 Mbits of on-chip RAM for buffering, packet handling, or intermediate storage in dataflow and signal-processing pipelines.
• Custom logic and hardware acceleration  Implement application-specific accelerators and proprietary state machines using the 55,296 logic elements to offload compute from software.

Unique Advantages

• High logic capacity: The combination of 6,144 CLBs and 55,296 logic elements supports complex, large-scale designs within a single FPGA, reducing board-level component count.
• Substantial on-chip memory: Approximately 5.9 Mbits of embedded RAM minimizes dependency on external memory for many buffering and streaming tasks, simplifying board design.
• Extensive I/O connectivity: 640 I/O pins enable broad interfacing options for multi-channel systems and dense peripheral integration.
• Compact, surface-mount package: The 1148-BBGA (35×35) FCBGA package delivers high pin density in a form factor optimized for modern PCB assembly.
• Commercial-grade reliability: Rated for 0 °C to 85 °C operation and RoHS compliant, suitable for standard commercial embedded products and systems.
