XC4VSX55-12FFG1148C

The XC4VSX55-12FFG1148C is a Virtex®-4 SX field programmable gate array (FPGA) offered in a 1148-ball FCBGA package. It provides a high count of programmable logic, on-chip memory, and I/O resources for commercial electronic designs requiring substantial logic and memory integration.

Designed for surface-mount assembly and RoHS compliance, this device targets commercial applications that operate within a 1.14 V–1.26 V supply window and an ambient temperature range of 0 °C to 85 °C.

Key Features

• Programmable Logic  55,296 logic elements provide a large fabric for implementing complex digital designs and custom logic functions.
• Embedded Memory  Approximately 5.9 Mbits of on-chip RAM (5,898,240 bits) to store data, buffers, and application state without external memory for many functions.
• I/O Resources  640 user I/O pins support extensive peripheral interfacing and parallel I/O connectivity directly from the FPGA package.
• Power and Supply  Operates from a 1.14 V to 1.26 V supply range to match system power-rail requirements for the device family.
• Package and Mounting  1148-ball FCBGA package (supplier device package: 1148-FCPBGA, 35×35) optimized for surface-mount PCB assembly and dense board layouts.
• Operating Conditions  Commercial grade device rated for 0 °C to 85 °C operation.
• Environmental Compliance  RoHS compliant for lead-free manufacturing and regulatory alignment.

Typical Applications

• Commercial Embedded Systems  Use the large logic capacity and on-chip RAM for complex control, signal processing, or protocol handling in commercial equipment.
• High-Density I/O Interfaces  Leverage 640 I/Os to connect multiple peripherals, sensors, or high-pin-count interfaces directly to the FPGA fabric.
• Memory-Intensive Functions  Employ approximately 5.9 Mbits of embedded RAM for buffering, data queues, and intermediate storage within the FPGA design.

Unique Advantages

• High Logic Capacity: 55,296 logic elements enable implementation of large custom logic blocks and complex state machines without partitioning across multiple devices.
• Significant On-Chip RAM: Approximately 5.9 Mbits of embedded memory reduces dependence on external memory for many applications, simplifying board design.
• Extensive I/O Count: 640 I/Os provide flexibility for multi-channel interfaces and parallel connectivity, reducing the need for external multiplexers or expanders.
• Surface-Mount, High-Density Package: The 1148-ball FCBGA (35×35) package supports compact PCB layouts while delivering high pin count in a single package.
• Commercial Temperature Rating: Rated for 0 °C to 85 °C operation to meet typical commercial application environmental requirements.
• RoHS Compliant: Conforms to lead-free manufacturing practices to support regulatory and customer requirements.
